Purpose
- To clear obstacles.
- Pinnacles.
- To clear turbulence.
- Night landing.
Objectives
- To clear the object.
- To maintain ETL until hover.
Performance standards
- Clear the object between 50 to 100'.
- Maintain a descent of less than 300' per minute.
CAUTION: Avoid SWP.
Approach Pattern

Approach notes
- 15° for practice. In actual conditions, the angle depends on obstacle height. Keep the minimum angle to clear.
- If wind: land into the wind or at crosswind, but avoid a tail wind.
- No steeper approach than needed to clear obstacles.
- Arrive at hovering altitude, attitude, and zero ground speed simultaneously.
Common errors
- Improper collective in maintaining the angle of descent.
- Failing to make pedal corrections to compensate for collective pitch changes.
- Slowing excessively to remain on the proper angle of descent.
- Failing to determine when ETL is being lost.
- Failing to arrive at hovering altitude, attitude, and zero ground speed simultaneously.
- Too much cyclic close to the surface.
- Failure to align skids with direction of travel.
