DEFINITION:

Environmental hazards, which mostly occur during the critical take-off and landing phases, can lead to potentially dangerous situations. Analytical and experimental techniques (simulation and flight tests) are used to identify the effects of these hazards. For analysis and prevention of accidents and incidents, it is investigated if the aircraft remains controllable (stability) and/or has sufficient performance for a go-around or evasive manoeuvre. For each hazard, the stability, control and performance sub domain activities are undertaken as described in 501 until 504, using sufficiently accurate models of the hazards their interference with the aircraft’s dynamics.

SUBDOMAINS:

1. Take-off and landing in severe crosswind.
2. Windshear and microbursts (usually in combination with turbulence).
3. Turbulence/ gusts.
4. Terrain and airport conditions (terrain profile effects on radar altimeter, wind interference from buildings).
5. Wake vortex effects from other aircraft.
6. Icing conditions / heavy precipitation.
