SEQ 001
Unreliable airspeed indication may be caused by a radome destruction or frozen pitots.
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 %.IMMEDIATE ACTIONS I
— AP/FD OFF
— A/THR OFF
— FLAPS MAINTAIN CURRENT CONFIG
— SPEEDBRAKES CHECK RETRACTED
NOTE : If failure is detected while in CONF FULL and go-around is initiated, select CONF 3.
— L/G UP WHEN AIRBORNE
IMMEDIATE PITCH ATTITUDE AND THRUST GUIDANCE
* With slats extended :
— THRUST LEVER MCT
— PITCH ATTITUDE 12.5°
* In clean configuration :
— THRUST LEVER CLB
— PITCH ATTITUDE below FL 100 10°
— PITCH ATTITUDE above FL 100 5°
Respect the Stall warning, if in alternate law.
Ground speed variations can provide valuable short-term information at low altitude.
The FPV is unreliable, if the altitude information is affected. In other cases, it is a valuable aid in establishing a safe flight path.
WHEN FLIGHT PATH IS STABILIZED I
— PROBE WINDOW HEAT ON
— ATTITUDE/THRUST ADJUST
Adjust attitude and thrust, according to the table below.
