Hi BOAC,

'alpha floor' which is as I understand it is an AB 'copyright' term
Not so. We had this protection on Lockheed TriStars in the 70s - PFM. With one hand on the TLs, we could feel when this protection came in - and manually dampen out any over enthusiastic TL movement. Can't you do this on 737s?

I don't have the manuals any more - but I think the threshold was 1.3 VS in normal flight and 1.25 VS on GA. Maybe 411A could remind me?
