2 h 10 min 47: The FD 1 and 2 become available again (modes HDG/ VS).
The selected heading is 34°.
The vertical speed is 1,500 ft/min.
The thrust levers are moved back to 33° (2/3 of the IDLE / CLB range). The N1 decrease to 85% in 4 seconds.
@2 h 10 min 47: Selected V/S equals V/S ~ 1500ft/min as CONF correctly stated.
The first 10s the FD bars will be flashing, just before STALL it would have been steady.
During the STALL (negative V/S) the FD order would have been SS UP (in reference to +1500ft/min), Max Guidance is hard limited at 6000ft/min.
However, soft limits are build in and that will make it difficult to determine the exact FD Pitch Bar position.
- FD bar order will never guide into Vmo/Mmo or
below VLS (VLS-5 if VLS = target)
was VLS available? and if so was airspeed already below VLS? and if so will it guide to reach VLS?
FCOM section 1.21.00 states:
Note :
When flying with FD bars only (AP OFF), the FMGS adjusts the pitch bar so that VLS is maintained.
However, no triple click is generated and the V/S target display on the FMA remains unchanged.
