Landed this morning LAX cmng from Europe, it was rough over the Rocky's/Sierras. We dropped 300ft due large wind shift and AP didn't hold. AP kicking off in turb on this a/c is a first for me(74-4). Loved having the separate pitch/roll AP mode on the 74-2, you just clanged the pitch and roll via those thumb wheels, AP trimming was 1/2 rate I believe, it worked wonderful, even going trough CB's. Just forgot what that system was called.
Respect for the jet jockeys in those regional hoppers.
