Windshear

Question 1

When are windshear alerts available

Answer 1

During takeoff, approach and landing below 1500 feet radio altitude

Question 2

Which system provides a warning when the aircraft is IN a windshear

Answer 2

GPWS

Question 3

In the NG, which system provides alerts for excessive wind shear ahead of the airplane

Answer 3

Weather Radar

Question 4

In the NG, when does the weather radar begin scanning for predictive windshear

Answer 4

Thrust levers set for takeoff OR inflight below 2300 feet radio altitude

Question 5

In the NG, what are the 3 predictive windshear alerts issued

Answer 5

WINDSHEAR AHEAD - Enabled during takeoff and 1200 feet RA

GO AROUND WINDSHEAR AHEAD - Enabled during approach below 1200 feet RA

MONITOR RADAR DISPLAY - Enabled during takeoff and approach below 1200 feet RA

Question 6

When should the windshear escape manoeuvre be accomplished

Answer 6

WINDSHEAR warning

Unacceptable flight path deviations below 1000 feet AGL

Question 7

What defines ‘unacceptable flight path deviations’ below 1000 feet

Answer 7

15 knots of airspeed

500 FPM vertical speed

5º pitch attitude

1 dot glide slope displacement

Unusual thrust level displacement for a significant period of time

Question 8

Pilot actions for wind shear escape manoeuvre

Answer 8

Disengage autopilot

Push TOGA

Aggressively apply maximum thrust

Disengage autothrottle

Roll wings level and pitch towards 15º

Retract speedbrakes

Follow flight director TO/GA guidance if available
