 Posted: Sun Mar 29, 2009 9:16 pm Post subject: 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?

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.

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.

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.

You could very well be right. I flew the L-1011 but retired 12 years ago and can’t remember where I laid my pen down two minutes ago any more. Jim

I flew a stethoscope and scalpel.... along with being a flight surgeon in some airplanes and helicopters but could never log "stick time:  Back in the good ol' days of medicine, it allowed me the ability to have a turbo-commander - at 70 gals per hour/ but no longer! Lucky to have a glastar that burns 7 gals per hour/
Larry Pullen and Tom LeBootllier are good buddies of mine from Delta who have flown my commanders when we have gone fishing. They've long lost their medicals due to heart problems. but we stay in touch.

Subject: 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?

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.

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.

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.

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.
