Subject: | S-Tec A/P Disconnect Warning? |
Robert,
My 500A was the one that S-Tec used for the STC after I hounded them for
three years. I had them install the 65 with all the whistles and bells and I
also was used to big iron where there was a warning when it disconnected.
That has been my only disappointment in that autopilot. I looked at my map
that was on a clip board and accidently laid it on the disconnect switch. We
were at night IFR and it started to drift off before I caught what had
happened. I have thought about putting a small cup under the switch so that
would not happen again but have not done it yet because I have not been able
to fly much in the last two years. A friend of mine drew out the plans for
putting trim and disconnect switches on the right side but have not done
that either. It has been a really good autopilot.

Commanders-
Anyone here have much experience with the S-Tec System 65 autopilot?
At issue is whether or not there should be an aural warning when pressing
the A/P disconnect switch.
I'm spoiled by all the transport time where the A/P disconnect is announced
at about 5,000db... just to make sure you notice it.
I find it strange that when I hit the disco button on this autopilot- it
quietly releases the airplane without so much as a peep. What if it
disconnects in flight on it's own for some reason? EA301?

Assuming you are referring to the red disconnect switch on the yoke (horns)

delayed in any fashion. Once on my turboprop commander, by myself, night
time, tired after a weekend of AF Reserve duty at Carswell, very busy (ATC
-
go fast to the OM at Hobby!)) I got very busy over the OM, and was flying
the autopilot coupled ILS approach - the elevator command went fairly
rapidly nose up as I lowered gear, and pulled back turboprop power to fligh
t
idle to slow down - it slowed down faster than I realized, and the AP
command was to stay on the glideslope, which meant go up, pitch up.
fortunately, I was aware and on top of it and was able to smoothly kill the
autopilot with the red quick dissconect on the yoke as I nosed it over a
little and added power. Any delay in doing that with a switch override -
could cause someone to have to fight the autopilot (which one COULD do - bu

disconnect.
I didn't stall - but it scared me ( I was IMC during this - broke out
shortly later) - will be good to see what the big iron guys have to say
about this.
As a flight surgeon, it made me review what "my" limits should be in flying
IMC when tired, at night and single pilot. Something everyone should think
about.

Subject: | S-Tec A/P Disconnect Warning? |
I was not going to change the switch, just put an upside down cap under it
so I can get to it but it would be protected from being accidently punched.
The L-1011 accident in FL many years ago is why the airlines went to the
warning. I have been surprised that the light plane auto pilots don't have
that. What did you fly in the AF Reserve? To tell you how old I am I flew
the B-47 and will have had my license 50 years the 24 of this month. I flew
for Delta for almost 33 years. My medical is in jeopardy though. They have
had it for four months and finally sent me a letter that it was going to the
neurologist. At least they have not said no yet. I had 9 different Drs.
check me from stem to stern and found nothing so I think it was what I
thought all along. I had been under a lot of stress with my wife's death and
we had painted the house inside and put down new carpet. The smells is what
I think was my problem because I have not had it since.

Jim;
I think the L-1011 accident was because the autopilot on the L-1011 had
'control wheel steering', the crew pushed forward on the yoke trying to
check or change a gear light, and put enough pressure on the yoke to
start a very slow, 50 FPM as I recall decent. Since it was a manual
input the airplane thought that was what was desired and the 250 ft.
altitude warning was bypassed. They went back and rewired that command.
As I understand it, the auto pilot was never disengaged. That and some
non normal terminology from ATC, such as "Eastern, everything OK"
instead of asking why they had left their assigned altitude. As normal,
it was a series of mistakes that let to a tragic accident.

Assuming you are referring to the red disconnect switch on the yoke (horns)
-- I'd be cautious about putting anything that makes a quick disconnect
delayed in any fashion. Once on my turboprop commander, by myself, night
time, tired after a weekend of AF Reserve duty at Carswell, very busy (ATC -
go fast to the OM at Hobby!)) I got very busy over the OM, and was flying
the autopilot coupled ILS approach - the elevator command went fairly
rapidly nose up as I lowered gear, and pulled back turboprop power to flight
idle to slow down - it slowed down faster than I realized, and the AP
command was to stay on the glideslope, which meant go up, pitch up.
fortunately, I was aware and on top of it and was able to smoothly kill the
autopilot with the red quick dissconect on the yoke as I nosed it over a
little and added power. Any delay in doing that with a switch override -
could cause someone to have to fight the autopilot (which one COULD do - but
t would be unusally hard push).... so I'd be careful changing out the quick
disconnect.
I didn't stall - but it scared me ( I was IMC during this - broke out
shortly later) - will be good to see what the big iron guys have to say
about this.
As a flight surgeon, it made me review what "my" limits should be in flying
IMC when tired, at night and single pilot. Something everyone should think
about.

Subject: Commander-List: S-Tec A/P Disconnect Warning?
Commanders-
Anyone here have much experience with the S-Tec System 65 autopilot?
At issue is whether or not there should be an aural warning when pressing
the A/P disconnect switch.
I'm spoiled by all the transport time where the A/P disconnect is announced
at about 5,000db... just to make sure you notice it.
I find it strange that when I hit the disco button on this autopilot- it
quietly releases the airplane without so much as a peep. What if it
disconnects in flight on it's own for some reason? EA301?

Subject: | S-Tec A/P Disconnect Warning? |
I took my physical for the AF at Carswell and went through the altitude
chamber there too. This was in 1959. I almost forgot I got a B-36 ride there
too. I live in Denton and got on the 100th BW list and found out the
navigator we had on the crew at Pease AFB lives in Arlington and I joined
the QB's and ran in to t he Ops Officer of one of the squadrons lives in
Dallas. I had not seen either of them since 1963.

Subject: | S-Tec A/P Disconnect Warning? |
Jim-
Thanks- I suspected this would be the case. In the pin diagrams there is
mention of wires for an aural warning, but nobody at S-Tec could tell us
why- or how to implement them in the installation. I suspect it was part of
the design that was never implemented.
So far I'm really enjoying the 65 autopilot. It's an older design that is
missing some of the VNAV/LPV capabilities of the newer digital autopilots-
but most of the transports I've flown didn't have those capabilities either-
so I'll probably not miss them. And then there's the old decision making
theory that while flying myself around single pilot- I probably shouldn't
put myself into a position to need those capabilities. ;-)

Robert,
My 500A was the one that S-Tec used for the STC after I hounded them for
three years. I had them install the 65 with all the whistles and bells and I
also was used to big iron where there was a warning when it disconnected.
That has been my only disappointment in that autopilot. I looked at my map
that was on a clip board and accidently laid it on the disconnect switch. We
were at night IFR and it started to drift off before I caught what had
happened. I have thought about putting a small cup under the switch so that
would not happen again but have not done it yet because I have not been able
to fly much in the last two years. A friend of mine drew out the plans for
putting trim and disconnect switches on the right side but have not done
that either. It has been a really good autopilot.

Subject: Commander-List: S-Tec A/P Disconnect Warning?
Commanders-
Anyone here have much experience with the S-Tec System 65 autopilot?
At issue is whether or not there should be an aural warning when pressing
the A/P disconnect switch.
I'm spoiled by all the transport time where the A/P disconnect is announced
at about 5,000db... just to make sure you notice it.
I find it strange that when I hit the disco button on this autopilot- it
quietly releases the airplane without so much as a peep. What if it
disconnects in flight on it's own for some reason? EA301?

When Robert first posed this question, I thought oh yeah, the Lears I flew
(part 25 cert) had aural warnings.
Then I remembered that the brand new Cessna 421C I flew in 1978 had aural
warnings as well. So its not a Part 23 vs 25 thing I guess.

It has been so long since I flew IFR that I would not dare try it unless it
was a high ceiling. I have filled that square. If I don't get my medical
back I may have to sell the plane anyway.
