Windshear

Question 1

Reactive WS works from when to when ?

Predictive WS works from when to when ?

Answer 1

R - liftoff to 1300ft/ LNDG 1300ft to 50ft at least Config 1
P - A/C below 2300 ft. On take-off Roll the aural warning is inhibited at speeds greater than 100kt. Until 3’sec or 50 ft after T/O

Question 2

What are the Aural warnings associated with WS warnings ?

Answer 2

Speed, Speed, Speed = low energy warning before alpha floor activation
WINDSHEAR AHEAD = predictive warning before T/O
MONITOR RADAR DISPLAY = ON APPROACH predictive warning
‘'’WINDSHEAR, WINDSHEAR, WINDSHEAR””
Reactive for T/O and Approach

Question 3

W/S ahead "RED"  ( Reactive )
before t/o - delay
1.  T/o run - reject
2.  Airborne - TOGA
3.  Landing - Go Around

Answer 3

W/S ahead "AMBER"  ( Predictive ) 
Apply precautionary measures.
1.  Select flaps three 
2.  MG speed
3.  FD on.

Question 4

Before T/O :
1. Delay
2. Assess
3. Select TOGA
BEFORE V1, T/O should be rejected

Answer 4

After V1, 
1.   TOGA
2.   Rotate normally
3.   Follow SRS
DURING CLIMB - maintain TOGA, USE AUTOPILOT 
Beware of A/P disengagement from (a prot)= angle.
Follow SRS, if no FD, Intial pitch 17.5 ^.
DO NOT CHANGE CONFIGURATION !!!
Approach/Landing=
1.   Delay
2.   Assess
3.   Flaps 3
