QRH Flashcards
What indication would suggest wind shear if no wind shear aural alert is heard?
- 15 knots indicated airspeed
• 500 fpm vertical speed
• 5° pitch attitude
• 1 dot displacement from the glideslope
• unusual thrust lever position for a significant period of time.
Which manoeuvre could possibly require flying at intermittent stick shaker without initiating the stall recovery procedure and what is the limitation? When is this relevant?
Wind shear escape manoeuvre. The pitch attitude that results in intermittent stick shaker or initial buffet is the upper pitch attitude limit. To maintain terrain separation! Do not exceed Pitch Limit Indication
Which manoeuvre’s could possibly require flying at intermittent stick shaker without initiating the stall recovery procedure and what is the limitation? When is this relevant?
EGPWS & Wind shear escape manoeuvre. The pitch attitude that results in intermittent stick shaker or initial buffet is the upper pitch attitude limit. To maintain terrain separation! Do not exceed Pitch Limit Indication
What is the wind shear escape manoeuvre during the take off roll close to or after V1?
How is this different to predictive wind shear?
At VR, rotate at a normal rate toward a 15 degree pitch attitude. Once airborne, perform the Windshear Escape Manoeuvre.
Predictive wind shear will warrant an RTO manoeuvre below V1.

What are the key differences between Windshear escape manoeuvre and EGPWS manoeuvre?
Wind shear manoeuvre requires an initial pitch to 15° attitude , followed by following the flight directors and then increased to PLI’s if terrain becomes a threat.
EGPWS requires an initial pitch to 20° attitude, and increased to PLI’s if terrain remains a threat.
What action is required if a EGPWS CAUTION is heard?
Correct the flight path, airplane configuration, or airspeed.
What are the Windshear escape manoeuvre steps?
- Disengage the autopilot
- Push either TO/GA switch
- Aggressively apply maximum thrust
- Disengage autothrottle
- Simultaneously roll wings level and rotate toward an initial pitch attitude of 15°
- Retract speedbrakes
- Follow flight director TO/GA guidance (if available)
What are the EGPWS warning response steps?
- Disengage the autopilot
- Push either TO/GA switch
- Aggressively apply maximum thrust
- Disengage autothrottle
- Simultaneously roll wings level and rotate toward an initial pitch attitude of 20°
- Retract speedbrakes
- If terrain stays a threat, continue rotation up to the pitch limit indicator (if available) or stick shaker or initial buffet.
What is one commonality with the EGPWS and Windshear manoeuvre?
Both manoeuvre prohibit changing flap or gear configuration until windshear or terrain is no longer a safety concern.
Should the following: “DESCEND” (fly down) TCAS instruction below 1000’ be followed?
No
What is the TCAS RA manoeuvre? When must this manoeuvre NOT be actioned?
- Disengage the autopilot
- Disengage auto throttle.
- Smoothly adjust pitch and thrust to satisfy the RA command.
- Follow the planned lateral flight path unless visual contact with the conflicting traffic requires other action.
When a descent is instructed below 1000ft AGL
Should you disconnect the autopilot if you receive a TCAS RA?
Only if manoeuvring is required?
What actions are required if in landing configuration whilst receiving a climb TCAS RA?
Disengage the autopilot and disengage the autothrottle. Advance thrust levers forward to ensure maximum thrust is attained and call for FLAPS 15. Smoothly adjust pitch to satisfy the RA command. Follow the planned lateral flight path unless visual contact with the conflicting traffic requires other action.
Verify maximum thrust set. Position flap lever to 15 detent.
