I really can't recall anything in Boeing literature referring to FD's off if not being used.Eric Janson wrote: ↑Thu Feb 09, 2023 4:19 amThe report isn't clear - I'm guessing there were FDs but the FO started the turn with the FDs showing to continue straight ahead.
Not sure if they had the single cue FD or the cross pointer type.
When I flew Boeing the procedures were to turn off the FDs if you were not going to follow them - not sure if this is still the case.
I'm sure they got a GPWS warning - that's probably when the Captain took over.
FDs or not - this should never have happened.
I lost all FD indications right at lift off recently - I just set the appropriate pitch and kept wings level. They came back after 5-6 seconds. A non event.
I do what the effo did here on a regular basis. While PM is looking for direct to waypoint, I'll commence a turn in the direction of the waypoint. The vertical FD will show me off the intended path but the pitch FD will always command for altitude (in VNAV/LVL CHG). That one i will follow in the turn. I wonder why he did not do the same.
A highly restrictive and punitive environment like QR will dissuade even the best to not turn off any guidance for fear of getting canned. So I'm quite certain the FD's were on. But weirder things have happened.
No one has mentioned fatigue yet. Rosters in this part of the world are brutal to say the least. That has to be a factor at 2am LT.
