Is it generally good practice to disengage A/T when disengaging the AP?I have had quite a few problems staying on the glideslope while maintaining safe airspeed with A/T turned on until I hit the DH and ultimately crashed, because A/T could not react quick enough to keep me from stalling.

I don't fly Airbus aircraft but with all the Boeings I fly like the PMDG and Level D 767, I leave A/T on until on short, short final. This is what was recommended to me by a Major Airline 767 Check pilot.

Yea, I think it all depends on airline policy. Southwest, so I have read, doesn't even allow the operation of A/T and even VNAV at all.

Airbus say (in fact without checking I think recommend) that you can use autothrust through the entire approach until retarding for landing.

I think you leave speed 'managed' on finals right down to when levers are retarded (edit - as Howard said)- I do it this way with the PSS panels/fdes and have no problems.regards,Markhttp://i14.photobucket.com/albums/a319/markrey/lsd2.jpgXPHomeSP2/FS9.1/3.2HT/1GIG/X700pro256

Well, my problem was that i left my A/T on yesterday, as usual, but during my approach last night, which i have decided to fly by hand with only the A/T turned on, I had major problems with the thurst.The weather was pretty good, but gusty winds made the A/T very unpredictable. During my final, I was repeatedly greeted by the "too low, flaps" warning and had major trouble staying on the glideslope, although i was in managed speed mode.
