Thanks OG,
Just an observation....
....if done as a demo or ops check in a level D FFS, using idle thrust just to expedite a level entry from say a weight dependent ~200 KCAS at FL350 into AOA protection, hands-off it will drift on down at alpha prot no thrust increase, if the SS is cycled full aft aggressively to achieve a short term transient alpha max there is still no thrust increase....
Like clockwork at around Fl280 (0.53 IMN) thrust comes up and alpha floor is then annunciated.
But it is only a sim, and real air can do some strange things.
I agree it is unlikely it was an SFCC alpha lock indication, I believe that is annunciated by the slat/flap indicator display anyway (don't recall for sure).
It's just the word probably that is intriguing and the fact that the Captain would have had to take positive action to exit alpha floor and one would think observe the alpha floor annunciation extinguish. Of course he was 60 years old and I noticed myself that at that point my powers of observation were waning somewhat also.
