      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)
      -- 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 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

      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

      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.

      I find it strange that when I hit the disco button on this autopilot- it

      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.

        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

        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

      You could very well be right. I flew the L-1011 but retired 12 years ago and

      I flew a stethoscope and scalpel.... along with being a flight surgeon in

      in the good ol' days of medicine, it allowed me the ability to have a

      glastar that burns 7 gals per hour/
      
      Larry Pullen and Tom LeBootllier are good buddies of mine from Delta who

      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.

      Larry Pullen and Tom LeBootllier are good buddies of mine from Delta who

      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.

      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.

      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?

| 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.

      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.
