Subject: | Who is "Matt Dralle" & What Are "The Lists"? [Please Read] |
Dear Listers,
Who is Matt Dralle and what exactly are these Lists? Well, I've been working in
the information technology industry for over 20 years primarily in computer
networking design and implementation. I have also done extensive work in web
development and CGI design during this period.
I started the Matronics Email Lists back in 1990 with about 30 fellow RV builders
from around the world. Since that time, I have added 63 other kinds of aircraft
related Lists to the line up and numerous other List related services such
as the Forums, Wiki, Archives and Search Engine just to name a few.
For flexibility and reliability, I have chosen to run all of my own servers here
locally. Other List-related systems include a 1 Gigabit, fully switched network
infrastructure, a commercial-grade Netscreen firewall, a Barracuda spam filter,
a local T1 Internet router, and a commercial-grade business T1 Internet
connection with full static addressing.
The computer servers found here include a brand new, quad-processor Xeon Linux
server for List web services, a dual-processor Xeon Linux system dedicated to
the email processing List functions, and another P4 Linux system serving as a
remote storage disk farm for the archives, databases, and for an on-line hard
drive-based backup system with 3.2 Terra Bytes of storage, soon to be upgraded
to over 6 Terra Bytes! This entire system is protected by three large, commercial-grade
uninterrupted power supply (UPS) systems that assure the Lists are
available even during a local power outage! Speaking of power, imagine how much
electricity it takes to run all of these systems. One month this Summer,
I had a staggering $1368 bill for electricity alone!
I recently upgraded all of the computer racking infrastructure including new power
feeds and dedicated air conditioning for the room that serves as the Computer
Center for the Matronics Email Lists. This year I added another rack to house
the new MONSTER quad-processor web system that didn't quite fit into the
first rack! Here's a composite photo of the List Computer Center before the addition
of the second rack:

As you can see, I take running these Lists very seriously and I am dedicated to
providing an always-on, 24x7x365 experience for each and every Lister.
But building and running this system isn't cheap. As I've stated before, I don't
support any of these systems with commercial advertising on the Lists. It
is supported 100% through List member Contributions! That means you... and you...
and YOU!
To that end, I hold a List Fund Raiser each November and ask that members make
a small Contribution to support the continued operation and upgrade of this ever-expanding
system. Its solely YOUR Contributions that keeps it running!
Please make a Contribution today to support these Lists!

Bill,
Thanks again for your timely advice. Your approach is a good one. I
have a
portable 406 EPIRB for my boat, which I could certainly take with me
when I
fly.
I think I will go for the cheapest method of compliance and deal with
the
real safety issue separately.

Joe,
Re. 406 ELT, yes, but AOPA forced through changes to local regulations
to
allow portables, the failure rate of fixed ELT, in real world accidents,
is
greater than 95%, and the supposed "greater reliability, fewer false
activations of 406 " has NOT been achieved in practice. Indeed, the 406
system is VERY susceptible to false alarms from, would you believe,
common
microwave ovens.
Have a look for a website for GME Electrophone.
http://www.gme.net.au/epirb/index.php
You are stuck with silly regulations mandating equipment that only works
on
the rarest of occasions, so spend as little as possible, and have the
best
pocket 406 ELT/EPIRB/PLB on your person, in a pocket, lanyard attached,
whatever, so that where you goes, it goes. Not in your flight bag, not
in a
seat pocket, in your pocket.
The failure rates are from AOPA Australia records, they were validated
from
a post implementation review of our national legislation several years
ago,
(bureaucrats wanted to "comply with ICAO") and your Civil Air Patrol
also
has figures to show how high the failure rate is, in a real accident.
There is no magic, in most accident sequences, the aerial or aerial
cable is
wrecked, and 100% of ELT's don't work under water.
The failure rates are just as bad in airline accidents.
Remember that the US rules were a political kneejerk reaction to the
loss of
a high profile politician in Alaska, like most politically inspired
reactions, it has produced barely measurable results for a
multi-(probably
by now) billion $$$ cost. Across a small fleet in Australia, we saved
about
$22M AUD in NOT fitting fixed ELT, but requiring a portable for every
trip
over 50nm. In survivable accidents, there has been a nil failure rate of
activated portables.
If the same amount of money had been spent on pilot training ????
Cheers,
Bill Hamilton

Bill,
Thanks for the information. I am especially interested to hear that a
Mode-S transponder will be available soon. The only 2-1/4 inch Mode S
transponder that I know of is the Becker unit, and it would be good to
see
some competition in this space.
Anybody Down Under working on a 406MHz ELT for experimental/general
aviation?

Folks,
Slight correction, for COMs, read ICOM.
Cheers,
Bill Hamilton
Joe,
As the former Technical Director of AOPA Australia, I have considerable
knowledge of their reliability, and it is good.
MicroAir is also about to release a Mode S version of their transponder.
I should also declare that Phil Ainsworth, President of MicroAir, is a
very
old friend of mine, but I don't think that taints my view.
My experience of dealing with member's problems suggest that in
reliability,
they are second only to the small panel mount COMs, and somewhat better
than
several well known names, due to the relatively modern engineering and
electronic design
Cheers,
Bill Hamilton

Does anyone have any experience with MicroAir radios? I am thinking
about
using them in an open cockpit modified Skybolt. I plan on using PTT
switches for the intercom function, as I am not sure VOX would work in
an
open cockpit environment.
Does anybody have any experience with the new Xcom 760 radio that is
about
the same size as the MicroAir? These radios seem to be very similar in
design. The Xcom appears to be more powerful and to have a number of
additional features. Its intercom system is voice-activated, however,
which may not work in my open cockpit environment.
MicroAir makes a companion transponder as well. Does anyone have any
experience with this unit?
