WINDSHEAR AHEAD Memory Items

Question 1

Initial consideration

Answer 1

The “W/S AHEAD” message is displayed on each PFD. The color of the message depends on the severity and location of the wind shear.

Question 2

Second consideration

Answer 2

Note: When a predictive wind shear alert (“WINDSHEAR AHEAD” or “GO AROUND WINDSHEAR AHEAD”) is triggered, if the flight crew makes a positive verification that no hazard exists, then the alert may be disregarded as long as:

• There are no other signs of possible wind shear conditions, and
• The reactive wind shear system is operational

Known cases of spurious predictive wind shear alerts have been reported at some airports, during either takeoff or landing, due to the specific obstacle environment.

Always rely on any reactive wind shear alerts, however (“WINDSHEAR”)

Question 3

W/S AHEAD RED (Take Off) Indication

Answer 3

Associated with an aural synthetic voice “WINDSHEAR AHEAD, WINDSHEAR AHEAD”

Question 4

W/S AHEAD RED Before Takeoff

Answer 4

Delay takeoff, or select the most favorable runway

Question 5

W/S AHEAD RED During takeoff run

Answer 5

Reject takeoff

Note: Predictive wind shear alerts are inhibited above 100kt until 50’

Question 6

W/S AHEAD RED When airborne steps

Answer 6

THR LEVERS - TOGA
SRS ORDERS - FOLLOW

Question 7

W/S AHEAD RED When airborne considerations

Answer 7

The slat/flap configuration can be changed provided the wind shear is not entered.

Use full backtick if required

Note:
1) If engaged, the autopilot disengages when Alpha is greater than Alpha Prot
2) If the FD is not available, use an initial pitch attitude up to 17.5 deg. If necessary, to minimize the loss of height, increase this pitch attitude.

Question 8

W/S AHEAD RED When landing indications

Answer 8

Associated with an aural synthetic voice “GO AROUND, WINDSHEAR AHEAD”

Question 9

W/S AHEAD RED When landing steps

Answer 9

GO AROUND - PERFORM

Question 10

W/S AHEAD RED When landing considerations

Answer 10

Use full backtick, if required

Note:
1) If engaged, the autopilot disengages when Alpha is greater than Alpha Prot
2) If the FD is not available, use an initial pitch attitude up to 17.5 deg. If necessary, to minimize the loss of height, increase this pitch attitude.

Question 11

W/S AHEAD AMBER

Answer 11

Apply precautionary measures, as indicated int the supplementary techniques.
