Guys and Gals:
Here's William's explanation of his dual ignition setup in the 601XL - I
asked him for help on the subject and he asked me to forward the reply for
the group's benefit. I noticed there are a lot of 601XL builders using the
Corvair, so I'm copying the Zenith-list with this post:
Enjoy,
Scott Laughlin
A lot of people get focused on hardware in the ignition system and loose
sight of the
Two main points: It must work as a complete system and you must recognize
that the pilot is the weakest link in the plane. Here is what we fly, and
why we set it up this way:
On the 601XL's
Installation:
One DPDT switch high on the panel, centered in front of the pilot. Side 'A'
has one ignition on it and the primary fuel pump on it. this pump is wired
through the oil pressure cut off switch. Side 'B' has the same thing but the
fuel pump is not run through an oil pressure switch.
Starter is a button on the panel hit with the index finger of the throttle
hand without lifting it off the throttle. Key switch controls only the
master.
Operation:
Engine is started on the 'B' side because the pump will run without the
engine running. Both systems checked on run up. Take off and landing always
done on 'A,' because in the event of an accident, the fuel pump will stop
automatically.
Logic: Mark Langford inspired this design. The starter location is a Bob
Lester tip. Pilot takes off and the power drops for any reason, Just move
the switch to the other position. This eliminated the pilot having to
diagnose anything. With an alert pilot, the time is much faster than 1
second, and it always will beat any set up where the pilot has to look at a
gauge to know what switch to hit. Even if the pilot is at 100 feet, and he
waits 4 seconds, and restarts, he will loose only 50 feet or so. If you are
frequently clearing anything at your airport by less than 50 feet, or it
takes you more that for seconds to flip a switch and hit a button, you need
a whole new game plan....
This system is simple, proven, takes into account the pilot and the 601's
need for fuel pumps.
Do Not: wire the coils to 2 on off switches. Without fail, at some point you
will have them both in the off position.
Do Not: use Pertronics ignition parts in place of the points. They are
voltage sensitive, and quit working when the voltage drops. Points fly on
long after these stop working. If you are worried about switching ignitions
after one side quits suddenly, you want points because the almost always
fade out slowly. When the pertronics part is starved for voltage it quits
suddenly. and you cannot have a points back up because the pertronics part
covers the points cam.
Do Not: Adjust the points in a WW distributor to the same gap. I set them in
the machine to have the exact same timing. This sometimes causes the to have
slightly different, but in spec., point gaps. If you spot this and "fix" it,
you will have a bigger variation on rpm when switching from 'A' to 'B."

This whole diatribe leaves me with two big questions:
1. What is wrong with having both ignitions operating at once as is
commonly done on certified aircraft engines? This allows the pilot
to spend his attention on flying the plane instead of managing the
engine in the (apparently common for William's resurrected Corvair
engines) event of an ignition failure.
2. I find it ironic that a salesman who says the weakest part of his
customer's system is the customer gets such a zealous following.

Members of the Net.
This message has nothing to do with Zenith aircraft but I think =
it's important so I am posting it here for all to read and heed.
There is an on line scam going on and it works like this: You =
receive a message from someone in England who says they are producing a =
product of some kind and selling to clients in the United States. They =
need an agent here to receive the funds from their client and take 10% =

sounds easy. If you agree, you will receive a check for $10,000.00. =
from their accomplice here. You deposit the check to your checking =
account and write a check for $9,000.00 and send it to the scamer. The =
catch is the original check is no good and you will be notified by your =
bank that the check is bogus and you are out the $9.000.00 If you =
receive such an offer, agree to it accept the check from their US =
accomplice, deposit it to your account and wait until the bank notifies =

you will be out nothing.

Great...Right up until the switch fails!
All of this comes down to personal preference. On my Stratus I have the
primary ignition on the key switch and the second ignition, pump1 and
pump 2 all on separate on-off switches. The left and right systems are
wired from each independent battery.
For take off I run both fuel pumps and both electronic ignitions all the
time. I have a LOUD audible warning buzzer if I inadvertanty switch off
both pumps
I always have both pumps running for TO and landing. None of this is
wired through an oil pressure relay, not that I think this is a bad idea
necessarily, in fact it does give you a BIG warning your engine is about
to (or just has) seize. I personally couldn't imagine the stress in
waiting for the second pump to partially fill the float bowls,
particularly if you are having to wait for the second pump to prime and
suck form the tank some feet away (hence my pumps are in the wing roots)
....But that's just me
Note I have run both ignitions continuously for 400 hours without ill
effect...I don't know what the Corvair setup is though..

Heck, there are guys out there actively looking for Model A engines to put
on their Pietenpols! But I still would not call that "resurrecting" an
engine. All we're trying to do is build an airplane, for a variety of
reasons; cost, nostalgia, design appeal, etc.
As for WW calling the "customer" a weak link - I guess I would have to
agree. The design is tried and tested. The engines and props are tested. The
theory of flight is tested. The only thing untested is each individual's
ability to build something. My guess is that William makes those kinds of
comments to remind us that we need to check and double-check, even
triple-check, everything we do. We need to recognize the fact that we are
the wink link.
Scott, your contributions are numerous and positive. Thank you!

Ignoring the prejudicial tone of your message I'll toss-out some answers. If
you are actually interested in more answers to your first question just
search the Corvair list archives.
1a. MSD (the maker of the coil mixer used in the design) recommends against
using both sides at the same time. There is another coil mixer (from
Mallory??) which is spec'ed for dual operation.
1b. Unlike a dual-plug engine with wide pistons in the dual-coil,
single-plug design there is no appreciable RPM drop when one side is lost.
So if you are cruising on "both" and any of the redundant parts fail you
will have no indication.
1c. "apparently common...ignition failure" - this has no basis in fact.
Every aircraft is design to handle failure modes.
2. The majority of accident investigations end in a conclusion of "pilot
error".

Thanks for the heads up on this scam but I would differ in the advice given.
Never, ever respond to the scam e-mail. In doing so you confirm certain
information to the scammer that you would be better off not sharing. If you
do anything other than ignoring the e-mail forward it to someone like the FBI
or the Anti-Phishing Working Group. (http://www.antiphishing.org/)

Scott,
Thank you for sharing this information.
I am not going to get into the systems layout debate, or scrutinize the
possibility of a switch failing, but I am going to caution listers against
one major sin: insulting individuals, by name, that they have never met or
spoken to in person.
William Wynne is not a salesman. He has contributed far, far more to my
motivation and progress in building an airplane than I have come close to
compensating him for financially. He has given me hours of one-on-one
advising in his own hangar, welded a few small parts for me for free that
the university machine shop wouldn't touch due to liability, given me engine
parts for free to replace what my core engine was missing, allowed me to use
his tools for my own project when I lacked what was needed, took me flying
in his airplane, and even laughed it off when I damaged his wrist pin
fixture by not paying attention and crushing it too far in his hydraulic
press. My total payment to him: $59 for his conversion manual. He is an
honest, well meaning, experienced mechanic. He is not a salesman.
If you have other proven methods of making airworthy systems, go ahead and
explain your ideas. Question other peoples' ideas if you like. That is the
purpose of the list, and that is how new ideas are shared. We all
appreciate input.
Do not attack the credibility of individuals, especially those that you do
not know. That is rude and it is not the purpose of the list.
I do not want any personal emails on this matter. I am in the middle of
final exams for my aerospace/mechanical engineering degree program and have
spent too much time on this list already.

--> Zenith-List message posted by: Paul Mulwitz <p.mulwitz@worldnet.att.net>
Let me start by expressing my continuing amazement at the logic of
some of the posters to this list.
In this one, a lister directs heavy personal criticism against me in
the name of not using the list to criticize individuals. I guess his
real message is it is ok to criticize anyone but the great William.
I am also amazed at the people who pointed out this list is an
inappropriate place for my comments and questions about engine
reliability while happily accepting the incredibly long post that was
announced as a duplicate of information posted on the Corvair
list. In the future I hope that any William Worshipers who want to
tell others that there is new information on the Corvair list will do
so with a link rather than a long winded copy of the information.
To those who I offended I offer my apology. To those who think this
list is not an appropriate place to question the value of Corvair
engines, I suggest you grow a thicker skin.
My special thanks to Craig for actually answering my question about
the manual ignition change/over switch. He pointed out that the
Corvair (like other auto conversion engines) only has one spark plug
per cylinder. That was new information to me and, I believe, very
important information. It points out that these engines don't really
have dual isolated ignition systems. Indeed, a single spark plug
fouling will put a cylinder out of commission until it is cleaned.

If they are legitimate you will probably know the sender, the return address
and the sending address are likely to be the same, etc. They also will not be
asking you to do things that are obviously illegal. Refer to me previous post

Subject: | Landing/Taxi Lights & wee bits |
--> Zenith-List message posted by: "Wentz, Don" <don.wentz@intel.com>
As the manufacturer of the LL kits for Van's Aircraft, I thought I would
throw in a few comments and reasons that I have found.
1 - Placing the leading-edge lights further outboard
- Eliminates glare from the light hitting the prop disc,
surprisingly visible on a dark night
- Helps illuminate the edges of the run/taxi ways
- Does not 'violate' the "D-Section" of the wing leading edge at
an inboard location, where stresses are higher and 'could' be a
structural issue
2 - I usually recommend a single light be mounted in the left or pilot's
wing on side by side RVs, especially the taildraggers, as visibility
over the nose on the ground can be limited on the right side. Not
likely an issue on the Zenith as the cowl is lower/narrower, most are
tricycle gear, so in the right wing makes some sense, except for the
possible benefit of the pilot being able to see the closest edge of a
dark taxiway on his left.
3 - We keep the opening in the top of the wing as small as possible -
you don't need or want light spreading up as it can be a
distraction/visibility issue in mist/haze/rain, especially if you try to
scan the horizon.
4 - Moving inboard 1 bay is not likely to cause an issue.
5 - Switching a 2 light setup with 2 switches is a good idea, more
flexibility.
6 - I ground everything to the airframe in my RV-6, 12 years and 925hrs
with no issues.
7 - Consider buying a $15 flasher from Galls Inc, flashing lights are
more visible.
Hope this helps.

Re: Landing light placement. I think the light location was chosen to
allow for the long range tank installation. I have the two tanks per
wing which prevents moving them inward. So, I'm betting that if you have
the single inboard tanks, moving them inward is the most practical thing
to do. It would move the weight a wee bit closer to CG, eliminate a we
bit of wire, and probably make the lights a wee bit more effective, and
perhaps some wee bits I'm overlooking. Are there any wee bits to favor
the more outboard location?

Subject: | Flying Report: 601XL/Corvair |
--> Zenith-List message posted by: "Phil Maxson" <pmaxpmax@hotmail.com>
This weekend, Gus Warren, flew my 601XL/Corvair from Edgewater, FL to my
home airport in Hackettstown, NJ. As many of you know, I completed my
engine in William's Hangar, and then took my plane back to them to finish
the cowling, paint and electrical system. Well, this weekend was the
culmination of my dream to build and fly my own airplane. Gus and I flew
around for a few days and he showed me how things work. And DOES IT EVER
WORK! Even with my limited experience in the plane I was making the
shortest take offs at my home field of all the planes out there. My plane
was able to make it to pattern altitude faster than I could have expected.
I don't have a vertical speed indicator so I can't give details, but it
climbs beautifully. This was worth waiting 6 years for!
Best of all, when anyone sees it for the first time, they ask what kind of
plane it is and they are impressed, but when the find out it is Corvair
powered, they are really interested.
I can't thank William Wynne and his gang at flycorvair.com enough. They
finished my plane, made it look beautiful, and then DELIVERED IT to me and
helped me become familiar with it. You don't find nice people like them
every day.
There is a video of my plane on the flycorvair.com web site:

2700 is NOT a high rpm. Think of all the cars that run 5000 to 8000 rpm
with only one plug. The speed of the flame front is very fast, especially at
2700 rpm. Plug redundancy may help flame front speed but tell that to a
Ferrari that is turning 12 grand on one plug per cylinder. I don't think it
is a factor to even consider with our relatively slow speed aviation
engines.

--> Zenith-List message posted by: Brandon Tucker <btucke73@yahoo.com>
Paul,
You are correct that if one spark plug fouls,
neither ignition would fire the plug, and the plug
must be cleaned. To my knowledge, it has never
happened, but it is a possibility. This is where the
extra 2 cylinders would be a good thing.
The piston area of the lycos is so large that
running both spark plugs will produce a much more
complete fuel burn, as proven by the RPM drop on mag
checks. The same results would likely not be realized
in the corvair with such a small diameter piston, even
with two spark plugs, so running both ignitions does
not help there. Only in the case of seamless failure
is it beneficial to run both. If there were not an
efficiency benefit of running both ignitions in
aviation engines, would we still always run both? The
answer is yes, because it is convention and how
everyone was taught, but would it be convention? I
learned in a turbo prop and am fairly new to piston
engine aircraft with only 300 hours in pistons, so I
feel unbiased here.
There are arguments that if you run both
ignitions all the time, you would have no indication
of a single ignition failure. Sure, you do a mag
check on the ground, but what happens if it fails at
takeoff? You continue on the other ignition unaware
that one failed, just for the second to fail after
climb out. If you run one at a time, you simply
switch to the other ignition on failure, and if on
climb out, can turn downwind, and land immediately.
This, in my opinion, is valid argument.
Having separate switches for the ignition systems
is a good concept as well, but it can be argued that
one could accidently shut them both off. Not likely,
but possible.
With a single switch controlling both ignitions
(like my system), switch failure can cause a forced
landing. It happened in an RV recently.
What is the best way to go? Who the hell knows.
If we keep it civil, we will all make more informed
decisions. Since the accident in the RV, I have
become aware that my automotive key switch could be a
weak link in my system, through civil textual
conversation on the corvair list. I have a 3 position
switch that allows me to run ignition 1, 2 or none. I
am considering a separate emergency ignition switch
run independently from the rest of my electrical
system feeding both ignitions, just in case the key
switch or ignition switch breaks. I have a header
tank, so all I need in an emergency is an ignition.

Congratulations Phil, I think your plane inspired me also.
The trip to SnF this year was just to help me decide if I was going to Corvair
or not. Seeing and hearing your plane put me over the edge.
I think I have a core in the works.

As others have pointed out, aircooled aircraft engines typically have
huge bores compared to any high revving car engines, some of which *are*
dual plugged. 911 Porsche for example, from IIRC, 1984 on.

2700 is NOT a high rpm. Think of all the cars that run 5000 to 8000 rpm
with only one plug. The speed of the flame front is very fast,
especially at 2700 rpm. Plug redundancy may help flame front speed but
tell that to a Ferrari that is turning 12 grand on one plug per
cylinder. I don't think it is a factor to even consider with our
relatively slow speed aviation engines.

--> Zenith-List message posted by: Matt Dralle <dralle@matronics.com>
Dear Listers,
Please read over the Zenith-List Frequently Asked Questions (FAQ) below. The
complete Zenith-List FAQ including the Usage Guidelines can be found at the
following URL:
http://www.matronics.com/FAQs/Zenith-List.FAQ.html
Thank you,
Matt Dralle

[ Note: This FAQ was designed to be displayed with a fixed width font such as
Courier. Proportional fonts will cause display formatting errors. ]
This FAQ can also be viewed in HTML online at the following address:
http://www.matronics.com/FAQ/Zenith-List.htm
************************************************************
******* LIST POLICIES AND FREQUENTLY ASKED QUESTIONS *******
************************************************************
PLEASE READ. This document contains Zenith-List policies and information
for new and old subscribers. Understanding the Zenith-List policies will
minimize problems for the Administrator, and will help keep the Zenith-List
running smoothly for all of us.
****************************************
*** How to Subscribe and Unsubscribe ***
****************************************
Simply go to the Web Page shown below and enter your email address and
select the List(s) that you wish to subscribe or unsubscribed from. You
may also use the handy "Find" function to determine the exact syntax of
your email address as it is subscribed to the List. Please see the
complete instructions at the top of the Web Page for more information.
The Subscribe/Unsubscribe web page is:
http://www.matronics.com/subscribe
Note that you will receive TWO conformation emails regarding your subsciption
process. The first verifies that your subscription/unsubsciption request
was received, and the second confirms that the process has been completed.
You should receive the first email within a few minutes of your request.
The second conformation will arrive in less than 24 hours. You cannot post
until you receive the second conformation email message.
*****************************
*** How to Post a Message ***
*****************************
Send an email message to:
zenith-list@matronics.com
Your message will be redistributed to everyone currently subscribed
to the List.
*****************************************************
*** SPAM Fighter - You Must be Subscribed to Post ***
*****************************************************
When a new post is received by the system, the From: line of the message
is checked and compared against the current subscription list. If the
email address is found, the message is passed on to the List Processor.
If the email address isn't found in the current list of subscribers, it
is dumped. This serves to very effectively thwart 99% of the SPAM that
gets posted to the Lists.
Remember, however, that the syntax of your email address is very important
with regard to the configuration of your email application such as Outlook
or Eudora. For example, the following two email addresses may be
functionally equivalent, but only one would pass the Matronics Email SPAM
test depending on which was syntax was subscribed to the given List:
smith@machine.domain.com
smith@domain.com
Either email address syntax is alright, just be sure that you configure
your email application to match *exactly* the address you've subscibed to
the List.
*****************************************************************
*** Enclosures Stripped Out - Can't Get a Virus From the List ***
*****************************************************************
Any enclosures that are posted to the List will automatically be
stripped off, and ONLY the plain/text portion of the message will be
forwarded to the List.
Please configure your Email application to send Plain Text Only, and
disable any "Quoted Printable" or "HTML" encoding whenever possible.
Because enclosures are stripped out of incoming posts to the List,
the likelihood of getting a virus from the List is extremely small.
If you do receive a message that appears to be from the List, and it
does include a virus, it is very likely that it was sent *directly*
to you from someone on the List who has a virus. This is a specific
kind of virus, and you should try to inform the sender, if possible.
The best protection against viruses is a good virus protection program
such as Norton Antivirus. State of the art in virus protection today's
world gives maximum protection with little or no negative impact on
the computer system. You can't afford to be without a good virus
protection program these days.
Note that some limited enclosure posting is now enabled on a number
of Lists. Allowed types include .jpg, .gif, .txt, .pdf, .xls, and
a few other similar types.
*******************
*** Digest Mode ***
*******************
Each day, starting at 12 midnight PST US, a new 'digest' will be started.
This digest will contain the same information that is currently appended
to the archive file. It has all of the headers except for the "From:"
and "Subject:" lines removed, and includes a message separator consisting
of a line of underscores.
Each day at 23:55 PST US, the day's messages as described above will be
combined and sent as a single message to everyone on the digest email list.
To subscribe to the digest list, use the same subscription web form
described above, and just select the Digest version of the List.
http://www.matronics.com/subscribe
Note that you *can* be subscribed to both the realtime and digest versions
of the List at the same time. This is perfectly acceptable.
Now some caveats:
* Messages sent to "zenith-list-digest" will be forwarded to the standard
email list. In other words, you cannot post messages only to the
digest List.
* If you are subscribed to both the regular List and the digest List, you
will receive the realtime postings as well as the digest at the end of
the day.
* If you reply to the digest email, your message will be forwarded to the
normal list associated with the digest. Important Note: Please change
the subject line to reflect the topic of your response! Also, please
*do not include all or most of the digest in your reply*.
****************************
*** List Digest Browser ***
****************************
An archive of all the List Digests can be found online in either plain text
or HTML format. These archives contain the exact Digest that was posted to
the Digest email list on the given day. The Digest Archives can be found
at the following location:
http://www.matronics.com/digest
*****************************************
*** The "DO NOT ARCHIVE" Message Flag ***
*****************************************
At times, your message may concern something that is revelent only to a very
small number of persons or to a limited area, and you may not wish to archive
it. In such a case, simply put the following phrase anywhere in the
message:
do not archive
Your message will not be appended to the archive, but will be sent to List
email distribution as normal.
**********************************************
***** READ THIS - Automatic Unsubscribes *****
**********************************************
Note that if your email address begins to cause problems such as bounced
email, mailbox is filled, or any other errors, your address will be promptly
removed from the List. If you discover that you are no longer receiving
messages from the Zenith-List, go to the following Web page, and look
for your email address and a possible reason for your removal.
The Matronics Email List uses utility called the "Email Weasel" that
automatically looks though the day's bounced email for addresses that
caused problems due to common things like "user is unknown", "mailbox
full", etc. If the Email Weasel removes your email address from the
Lists you will find record of it at the following URL:
http://www.matronics.com/unsubscribed
If the problem listed on the web site above has been resolved, please feel
free to resubscribe to the Lists of your choice.

*** Matronics Email List Wiki ***
*********************************
In an attempt to make it easy to store and find structured and often accessed
information, Matronics has installed a Wiki at:
http://wiki.matronics.com
The Wiki allows individuals to create web pages to contain useful information
for other users of the mailing lists and web site. Unlike an ordinary web page
where the content needs to be submitted to Matronics for inclusion, the Wiki
permits the users to construct their own pages and have them visible immediately.
While constructing pages for the Wiki is not difficult, some may not be
comfortable building pages. In that case, simply prepare the text and any
images and email it to:
wiki-support@matronics.com
One of the volunteers on that list will take your submission and construct
a Wiki page for you.
Often someone produces a particularly useful posting in email one one of the
Lists that would be of general interest. In that case Matronics may take that
post and convert it into a Wiki page.

*** List Support Contributions ***
**********************************
The Matronics Lists are run *completely* through the support of it members.
You won't find any PopUpAds, flashing Banner ads, or any other form of
annoying commercialism on either the Email Messages or the List web pages
associated with the Matronics Email Lists. Every year during November
I run a low-key, low-pressure "Fund Raiser" where, throughout the month,
I ask List members to make a Contribution in any amount with which they
are comfortable.
I will often offer free gifts with certain contribution levels during the
Fund Raiser to increase the participation. The gifts are usually donated
by companies that are themselves List members.
Your Contributions go directly to supporting the operation of the Lists
including the high-speed, business-class Internet connection, server
system hardware and software upgrades, and to partially offset the many
many hours I spend running, maintaining, upgrading, and developing the
variety of services found here.
Generally Contributions range from $20 to $100 and are completely voluntary
and non-compulsory. I ask only that if person enjoys the Lists and obtains
value from them, that they make a Contribution of equal magnitude.
Contributions are accepted throughout the year, and if you've just
subscribed, feel free to make a Contribution when you've settled in.
The website for making SSL Secure Contributions is listed below. There are
a variety of payment methods including Visa and MasterCard, PayPal, and
sending a personal check.
If you enjoy and value the List, won't you make a Contribution today to
support its continued operation?

Zenith-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the Zenith-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the Zenith-List in the manner described below may result
in the removal of the subscribers from the List.
Zenith-List Policy Statement
The purpose of the Zenith-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
- Occassional posts by vendors or individuals who are regularyly
subscribed to a given List are considered acceptable. Posts by
List members promoting their respective products or items for sale
should be of a friendly, informal nature, and should not resemble
a typical SPAM message. The List isn't about commercialism, but
is about sharing information and knowledge. This applies to
everyone, including those who provide products to the entire
community. Informal presentation and moderation should be the
operatives with respect to advertising on the Lists.

Zenith-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the Zenith-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the Zenith-List in the manner described below may result
in the removal of the subscribers from the List.
Zenith-List Policy Statement
The purpose of the Zenith-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
- Occassional posts by vendors or individuals who are regularyly
subscribed to a given List are considered acceptable. Posts by
List members promoting their respective products or items for sale
should be of a friendly, informal nature, and should not resemble
a typical SPAM message. The List isn't about commercialism, but
is about sharing information and knowledge. This applies to
everyone, including those who provide products to the entire
community. Informal presentation and moderation should be the
operatives with respect to advertising on the Lists.
