05 - TRAINEES’ ACTIONS
The best defence against a windshear encounter is to avoid it in the first place. Use your knowledge and experience combined with weather reports to assess the possibility of windshear and plan accordingly. If it is possible, delay take-off or landing, or plan a course of action to avoid the worst of the weather. The use of the groundspeed mini function will give added protection in strong winds.
The protection envelope is from lift-off to 1300 ft on take-off, and 1300 ft down to 50 ft for landing. In both cases, at least CONF 1 must be selected. If windshear is suspected for landing VAPP should be increased to VLS +15 kts.
Aural and visual warnings are generated when the airplane’s predicted energy level falls below a predicted minimum energy threshold. This is expressed as an angle of attack.
Know the indications and the correct response.
Do not change configuration and follow SRS orders closely. When following SRS orders be positive but smooth with your actions on the sidestick. Monitor V/S and pitch as together they are good indicators of the airplane’s energy. If FDs are not available, target pitch attitude should be 17°5.
Full back stick is always available. This might trigger alpha floor.
