CHINA AIRLINES
AOM A330-300
OEB ABNORMAL V ALPHA PROT
2.50/8
REV 25
In addition, in OP CLB or CLB with blocked AOA probes, the pitch order of the flight guidance may be affected by the value of the blocked AOA probes. Therefore, the aircraft may not be able to accelerate in order to reach the target speed.
This OEB also covers the abnormal system behavior in the case of a bent AOA.
PROCEDURE :
CAUTION : Monitor the Alpha Prot strip when it is visible.
!
when the Mach increases, If the Alpha Prot strip (black and amber) continuously increases and exceeds Green Dot (GD) speed in a stabilized wings-level flight path (without an increase in load factor) :
ONE ADR ........................................................................ KEEP ON TWO ADRs ............................................................................ OFF
The AP, FDs and A/THR are lost for the remainder of the flight. Switch two ADRs to OFF for the remainder of the flight, in order to revert to alternate law and to prevent undue Alpha Prot activation.
In case of dispatch with one ADR inoperative, switch only one ADR to OFF.
CAUTION : Risk of erroneous display of the VSW (stall warning speed) strip (black and red) and risk of undue stall warning.
SPEED.......................................................DO NOT INCREASE FPV USE.................................................................. CONSIDER CAPT (F/O) EFIS DMC.............................................. AS RQRD
! When at or above Safety altitude:
ALTITUDE ............................................DO NOT INCREASE Limit speed and altitude in order to limit the Mach number and to avoid undue stall warning.
AT ANY TIME, with a speed above VLS, if the aircraft goes to a CONTINUOUS NOSE DOWN PITCH RATE that cannot be stopped with backward sidestick inputs, IMMEDIATELY APPLY :
MEMORY ITEM
!
ONE ADR........................................................................ KEEP ON
TWO ADRs .............................................................................. OFF
