Subject: | Wiring Harness, GO480-G1B6, 560E |
--> Commander-List message posted by: "Bill Kirkwood" <bkirkwoo@elp.rr.com>
I am in the process of installing a "new" engine on my 560E and would like to order
a new ignition harness. Does anyone know the Champion part number that would
be appropriate?
Also, in the inter-cylinder baffling there is a hole with a rubber grommet in it
that appears to be where the ignition wires should be routed to the bottom cylinders.
These holes weren't used in the previous installation. Should they
be used? If not, should they be plugged so air doesn't go through them?
Thanks.

I have kept my powder dry but now have decided to stick my foot in _ _ IT. I
use both techniques-that is I generally use half flaps til short final then run
the flaps down as a means to bleed off some speed. If I am flying an approach
in the soup I will be in the landing configuration over the final approach
fix. I do the latter because (A) I would like to be as stable as I can as I
approach the earth in the WX and (B) for timing purposes on timed approaches.
I have learned most of my flying techniques from "old and senior airline farts".
Now I am one. One of best lines is " Indecision is the key to flexibility".

Subject: | flaps and flexibility |

So do answers given to this point change significantly when there is a
strong crosswind?
Last week a very unusual circumstance occurred at SNA: I took off on a
short flight to check out a couple of maintenance items. The ATIS was
calling the wind 200/7 and runways 19 were in use. The windsock confirmed;
perfectly normal day down here. I did a short flight and returned for a
practice ILS approach to 19R. Weather was CAVU and the air was relatively
smooth. As I got lined up on the approach I got my first indication that
things had changed: I had not been airborne for more than 20 minutes, yet
now on approach I had a WCA of at about 25 degrees to the right to remain on
the ILS. I was really surprised - what is going on here?. "John Wayne
tower, windcheck, please." "Winds 250 at 18 gusting 25". Interesting...
So I had the opportunity to land back at SNA [nice wide runway] with a
crosswind component of about 15Kts and gusting higher. This is an area where
I have precious little experience in my bird. As it turned out, this was
one of my better landings ["nothing focuses the mind so much as an imminent
hanging"], but I'm frankly unsure of any Commander-specific recommendations
for this kind of situation. On this day I used half flaps while carrying a
little extra airspeed for the gusts, and consumed significantly more runway
than I usually do.
What is the consensus on flaps and crosswinds? I have been taught [not
Commander-specific] that strong crosswinds should be met with minimal to
partial flaps. Agree/disagree for Commanders?
Separately, is there a maximum demonstrated crosswind component for Aero
Commanders?
Alan

Hi Alan,
Here at PAO we have frequent 90-degree crosswinds. At DVO, where I fly to
see my in-laws, the predominant winds are directly across the runway. I've
never modified my flap usage in those circumstances, and I can easily slip
the airplane down, landing upwind wheel first, and using no more runway than
usual.
I seem to recall that twins aren't required to demonstrate a maximum
crosswind component, and have never seen any for a Commander. I can say that
I've landed mine in a 30-kt. crosswind (yes...THIRTY!) without any hint of
loss of directional control. I also seem to recall that the max demonstrated
crosswind component for most singles is often the highest crosswind
experienced by the test pilots during certification....
If you want good crosswind practice, I suggest going to DVO (north of SF)
the next time you're up here!
Cheers,
/J

John:
Thanks for the feedback on x-winds.
...interesting that you mention DVO. There is a good likelihood that I will
do a fair number of SNA-DVO trips this year. Looking at AirNav, I don't see
any fuel or car rental available. Any experience with either there?

I am no airline jock or someone with the privileges that military training
offer. What I had I had to pay for at the local flying school back in the
60's. That was supplemented by many 'Oh sh.t, better not attempt that again'
over the years doing a lot of bush flying. After that disclaimer, back to
the topic.
On cross-winds I key in a slightly higher speed (for gusts as Alan said) and
full flaps. Even Cessna 150's will have all the flaps hanging out upon
landing. In rough air, as soon as I have firm contact with the runway, I
will raise all the flaps. In smooth air, I use the drag to reduce brake use.
Now, I know, many of you will say, one day you're gonna pull the wheels up
and have a very short step down to the runway, but I do a very short-final
check on wheels-down by actually touching (fondling?) the gear handle down
and locked (the Commander's unique lock) and so mentally confirming that the
other handle is the flaps. Raising the flaps drops all tendency to keep on
flying (in case of a gust) and rapidly gives me firm automobile qualities.
There is an exception, however, and that is when wind gusts rock the
airspeed indicator more than 10 knots. For fear of exceeding the flap
extension speed and reducing bending moment on the wing, I will decrease
flaps. Every situation requires its own judgment.
Now I am open to criticism. I can take it.
Nico

Alan,
There's an Enterprise about 15 min. away from DVO, and they will deliver a
car to you there. I recommend calling well in advance and being very
optimistic on your arrival time as it has taken them up to an hour past when
they say it'll be there for them to actually show up with the car. Their
contact info is:
ENTERPRISE
7401 REDWOOD BLVD
NOVATO, CA 94945-2423
Tel.: (415) 898-3500
There's Also Novato Cab at 415-485-1234. On weekends there are only 2 cabs
on duty and it can take them ~45 minutes to get to you.
There is Chevron Fuel on the field and they have a truck....I don't have the
phone number and can't remember the unicom freq. for them but it's posted at
the terminal and they've proven very accessible even at odd times.
Incidentally I twice did the same test that you did, only with one key
difference: they weren't voluntary...I actually had 2 complete hydraulic
failures, one in my airplane and one in someone else's semi-restored 500B.
The runway available in each instance was 7,000 ft and 5,000 ft
respectively. Both times I held the nose off and used aerodynamic drag to
slow the airplane down (and avoid nosegear collapse; both times I had no
green light for the nosegear). Both times I had to add power to keep the
nose off and make it to the end of the runway. The incident in my airplane
resulted in a very gentle nosegear collapse on the taxiway at about 5 kts.
(user error....I tried to get too clever while airborne after recognizing
the failure), and in the borrowed airplane it was a non-event. I never
thought about distances, but on hindsight I think both airplanes would have
stopped shy of 3,000 feet. I attribute this to holding the nose off to avoid
the nosegear collapse; it REALLY slows the airplane down on the ground and I
think it would be a viable tactic should you have the same problem.
The only good news coming from this experience is the recognition that there
are very few conventional failures that could be considered emergencies in
Commanders, and the fact that my nosegear collapse cost me only a bellcrank
and one gear door...whew!
Also, I discovered that while rolling out on the mains, with a little power
added, you can maintain elevator authority at very slow speed (~25kts?); I
kicked in some rudder, and turned 90 degrees onto the taxiway quite easily
with the nose pretty high in the air. I probably could have taxied under
power all the way to Morris' hangar before letting the nosegear collapse,
but that would have just made it easier for Morris to slap me for making
such a rookie mistake ;-). You know, the airborne one where I touched the
gear lever one too many times after the loss of hyd. pressure.

--> Commander-List message posted by: BillLeff1@aol.com
The Commander Aero Winglet, for the 500S was a copy of the factory tip for
the 695 series. It was first put on AvFuel's Shrike. It does help low speed
roll control bit does nothing for the high end.
It was certified as "no change in performance" to save having to prove the
numbers. Flutter test were done but no high speed computer modeling was done to
my knowledge. The engineers at Wright Patterson did look at them but again,
to my knowledge, they only gave an opinion. They did think that they were
about as good as you could get without a major re design.
They do look good and in my judgment really help low speed activities like
take off, low speed roll control, maybe even single engine climb. But there is
nothing to prove it.
Oh Yeah, I did the flight test for Dick.
There are some great reports on wing life expectancy floating around, I use
to have a copy but I cant find it. It showed the fatigue life calculations for
the different models based on hours and flight profile cycles. It was really
neat. Low altitude aerial survey significantly reduced the life of the
wing. I also saw the test facility at Norman, OK where they did the cycle life
test on the 1000. As I remember they bent the wings 33 inches at the tip and
pressurized the cabin to 21 psi before the cabin door blew off! It was cool!
When I saw it, they had reached 21K hours and were still testing.

Jets use full flap approaches to keep the engines spooled up to reduce
engine response time in the event of a go around or wind shear. Prop aircraft,
ie
Commanders, do not have that problem. So, full flaps when the landing is
assured is still proper in the Commander.
Jets also reduced the flap settings to meet Stage II and III noise
requirements and did carry that setting to landing. I know one case, the DC-9-30
series reduced the landing flaps from 50 deg. to 40 for vibration.
