ABNORMAL HANDLING
Hawker 800XP Pro Line 21
Section V - FLIGHT HANDLING
Aircrew Co-ordination
Pilot Flying:
Should focus attention on flying, taking appropriate action in response to call-outs in a windshear
encounter.
Pilot Not Flying:
Should focus attention on:
• Airspeed
• Vertical speed
• Altitude
• Pitch attitude
• Glideslope deviation
• Thrust
Any significant deviations from normal indications should be called out using standard flight
compartment call-out procedures.
WINDSHEAR RECOVERY TECHNIQUE
The importance of immediate recognition and action cannot be stressed enough.
The criteria for windshear recognition and recovery decision are:
Takeoff
1. 15 knots sudden variation of airspeed.
2. 500 fpm sudden variation of vertical speed.
3. 5
°
sudden variation of pitch attitude.
Approach
1. 15 knots sudden variation of airspeed.
2. 500 fpm sudden variation of vertical speed.
3. 5
°
sudden variation of pitch attitude.
4. 1 dot glideslope displacement.
5. Unusual thrust lever position for a significant period of time.
Takeoff (On Runway)
Recognition of windshear is difficult during take-off roll since airspeed is changing rapidly.
Prior to V
1
the takeoff should be rejected if a windshear is encountered and the decision is made that
sufficient runway is available to stop the airplane. After V
1
the takeoff must be continued.
