TECHNICAL RECOMMENDATIONS:
‐ Respect Stall Warning
To monitor speed, refer ‐ to IRS Ground Speed variations.
If remaining altitude indication is unreliable:
‐ Do not use FPV and/or V/S, which are affected
‐ ATC altitude is affected. Notify the ATC
‐ Refer to Radio Altimeter.
CAUTION If the failure is due to radome destruction, the drag will increase and
therefore N1
must be increased by 5 %. Fuel flow will increase by about 27 %.
AFFECTED ADR IDENTIFICATION:
Crosscheck all speed indications and Refer to FPE-SPD Speeds
If at least one ADR is reliable:
Faulty
ADR(s).............................................................................................................................
OFF
REMAINING AIR
DATA.................................................................................................... CONFIRM
Alternate sources may be used to evaluate the air data:
‐ IRS Ground Speed, taking into account altitude and wind effect.
If affected ADR(s) cannot be identified or all ADRs are affected:
ONE
ADR..........................................................................................................................
KEEP ON
Keep one ADR ON to maintain the STALL WARNING protection.
TWO
ADRs...............................................................................................................................
OFF
This prevents the flight control laws from using two coherent but unreliable ADR
data.

TRACT
Retract from 3 or 2 to 1, once CLB thrust is set.
Retract from 1 to 0, when the aircraft pitch is lower than the pitch for S speed (Refer
to
ABN-34-C UNRELIABLE SPEED INDICATION/ADR CHECK PROC - Level-Off
(Pitch &
Thrust Table) )
Once in clean configuration, Refer to ABN-34-C UNRELIABLE SPEED
INDICATION/ADR
CHECK PROC - Climb/Cruise/Descent (Pitch & Thrust Tables) for flight
continuation.
Other cases:
Refer to ABN-34-C UNRELIABLE SPEED INDICATION/ADR CHECK PROC -
