Good, I'm not the only one to give the rudder a little boot on final
sometimes. Doesn't slip like a Cub, but gets the job done and I don't have
to mess with power. We need a steeper approach than standard at home base.
Speaking of rudders, we noticed something last annual that was really tough
to see. On the bulkhead ahead of the pilot's feet (forgot the number) are
two rudder pulleys on either side of the airframe. They are a bitch to get
at. After pulling the side nose inspection panel off, we noticed a 1/4 inch
long crack at the top of the rudder pulley bracket. It takes some work, but
we also saw the same crack on the 'back' side of the bracket.
Since we saw it on the one bracket, we took a real hard look at the other
side and found the same two cracks on the opposite side pulley brackets. The
airframe's got about 8000 hours on it, and it is used for survey work where
rudder is used often to correct yaw while on flightlines. Aircraft has been
indoors for at least 20 years, maybe longer. These brackets are a bear to
get at. It's one of the few places on the Commander where I thought it could
have been made of a heavier gauge.
Talk about rudders and slipping got me to remembering this. I'd be
interested in hearing if anyone else has seen the same.

Around 1979 Commander decided to reduce the price of the 690B by removing
some of the standard equipment such as the co-pilot's HSI. They then lowered
the price about $100K.
The B-II was the completely equipped, higher priced, version. Systems and
mechanically they are the same.
Rockwell did the same thin when they introduced the 681B. It was just a
striped down 681 to lower the cost.

I was an instructor at TWA (then owned by American) when American Flight
587. To keep this short, it was determined that after encountering turbulence
from a 747 in front of it, the flying pilot over controlled the A300 aircraft
in the yaw axis.
This over controlling of the rudder by rapid direction reversal is called a
Rudder Doublet. Contrary to popular belief, transport aircraft are only
required to demonstrate full travel of the rudder (at or below maneuvering speed)
from neutral to full deflection then back to neutral. Demonstration of full
deflection from stop to stop is not required!
Boeing put out a great paper on the subject and proudly pointed out that
their aircraft have never had structural problems with their tails because of
the extra design margins in the Boeing Aircraft vs. their French competitors
aircraft.
Proper use of the rudder became a priority in training after that.

Tom,
With the IO-720, I'd use 14" and 2000 rpm. This is what I've found gave
equal performance (or lack of) to having one feathered on the long body MR RPMs.
If 14" MAP won't keep yours on the governor, you may have to up the MAP a bit.
This are approximate settings, of course. Each airplane seems to have a
different set-up.

Rudder deflection on the B747 is relative to speed. At higher speed you
can't get full deflection.

--> Commander-List message posted by: "Randy Dettmer, AIA" <rcdettmer@charter.net>
New Years Greetings..!!
Just wanted to share some great Commander flying this holiday week. Loaded
up the 680F day after Christmas with 3 pairs of skies, 2 snow boards, about
8 big bags of clothing and gear, Christmas presents, and 5 persons (my wife,
son & girlfriend, daughter...and me) for our non-stop flight from SBP (San
Luis Obispo, CA) to SLC (Salt Lake City) for a week of fun at my sister's
house in Park City, UT. Total flight time - less than 3 hours. Not bad
considering we had to go south through Palmdale & Las Vegas because bad
weather over the Sierras didn't let us go direct at less than the MEA of
14,300 feet (not pressurized). After a week of spectacular skiing and
family fun, we piled it all back into the Commander this morning (New Year's
Day) for the flight home. The terrible weather in California once again
prevented a direct route home, so it was SLC to VGT (North Las Vegas for a
fuel & burger stop), then on to SBP, where we entered the nasty weather
around Palmdale (30-40 knot headwinds). The commander performed flawlessly
with a smooth ride at 11,000 feet (while the airliners all complained about
turbulence in the flight levels), with an ILS approach to SBP in heavy rain.
After parking, I backed my Ford Explorer up to the plane with the hatch back
open and overlapping the engine nacelle & flaps. We unloaded all the gear
into the car without even getting wet...can't do that in a low wing
airplane.
Anyway, I once again find myself so appreciative of the great qualities of
our cherished Twin Commander, after transporting our family in comfort and
safetly through the winter skies...thought I'd share it with you folks, who
can appreciate it too.
Best wishes to all of you for a Great New Year in Commanderland..!!!

You are right, That is true of most Transport aircraft. I was an MD-80
instructor and it also had a rudder limiter. However at lower speeds the rudder
limiter allows full travel. On the A300 the problem is that it has very light
rudder pressures for full defection (33 lbs) due to the fly by wire flight
control system. It is very easy to over control.
In the case of flight 587 the flying pilot created so much yaw from side to
side that the rudder, vertical fin and both engines separated from the
aircraft. It was below maneuvering speed by a good margin.
Good rudder handling habits are important in any airplane!

To all in Commanderland,
Have a great New Year. We had a fine day running at about 47 deg C. A little
warm.
Had a wonderful visit from Moe and Linn. It was great to see them.
Flew my Super Cub for the first time on Wednesday. After a complete rebuild
and changing from US reg to Oz reg. Havent flown one of these things for about
15 years. Funny how quickly it all comes back to you. You discover things
like what a rudders is used for and what torque does in a grossly overpowered
aircraft. Its all come back and a blast to fly although I am beginning to become
a little afraid of birdstrikes from the rear. Comming over the fence at 40
kts, feels like you could walk faster. But you also land and take off in a very
very short space.
Now thats finished I will be back on the 680E. Hopefully that can be done by
mid year.
Best wishes from OZ
Richard & Jacqui

DNA: do not archive
--> Commander-List message posted by: dralle@matronics.com
Dear Lister,
Please read over the Commander-List Usage Guidelines below. The complete
Commander-List FAQ including these Usage Guidelines can be found at the
following URL:
http://www.matronics.com/FAQs/Commander-List.FAQ.html
Thank you,
Matt Dralle
Matronics Email List Administrator
******************************************************************************
Commander-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the Commander-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the Commander-List in the manner described below may result
in the removal of the subscribers from the List.
Commander-List Policy Statement
The purpose of the Commander-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.
