4.9. APPROACH
4.9.1. Descent
- throttle as required
- engine instruments check
WARNING:
Avoid prolonged operation with IDLE during the flight as the engine
may become overcooled and lose the power.
If higher descent is needed, there is possbility to extend flaps under 140 km/h,
and extend the undercarriage. Side slip is not efficient, steep descend is
reached with flaps III.
