| LOSS OF VISUAL REFERENCE DURING LANDING |
|
Definition
*1. Collective — Increase to climb.
Not only must descent be stopped to prevent impact with the surface, but
also a positive rapid climb is necessary to regain visual flight conditions.
Any delay may allow drift to develop, which could cause impact with
ground/obstacles.
Consideration should be given to external cargo jettison.
*2. Cyclic — Hover attitude (on instruments).
*3. Selected heading — Maintain. |
