System Description
4.20.34
MN-FLT-OH-201
In the above modes with the autopilot engaged, the autopilot disengages and the
F/D command bars (both pitch and roll) are removed one second after stick shaker
activation. When airspeed increases to the top of the minimum maneuver speed
(amber) bar, the F/D command bars (both pitch and roll) return and the autopilot
can be re-engaged. If the previous F/D pitch commands were ALT HOLD, VNAV
ALT (as installed) or VNAV PTH (in a level segment), the F/D pitch commands
return in MCP SPD mode. Both the Indicated Airspeed (IAS) display and the
speed bug will reference the existing airspeed when the F/D command bars return
into view. If the previous F/D pitch commands were V/S (flaps 15 or greater),
VNAV PTH (flaps 15 or greater), G/S or G/P (as installed), the F/D pitch
commands return in the previous V/S, VNAV PTH, G/S or G/P (as installed)
mode, respectively. For all cases the roll command returns in the previous mode.
Note:
It is possible that stick shaker does not occur simultaneously on both the
Captain and First Officer side due to AOA vane angle tolerances. In the
event that stick shaker does not occur simultaneously, F/D command bars
are removed one second after stick shaker activates on that side.
