Question 3

Settling with power is defines as:

Answer 3

Condition of powered flight in which the helicopter settles in its own downwash

Question 4

What three conditions must exist simultaneously for settling with power to occur?
1.
2.
3.

Answer 4

1. A vertical or near vertical descent of at least 300 FPM
2. Slow forward airspeed (less than ETL)
3. 20 to 100% of the available engine power

Question 5

Name at least three of six conditions that are conductive to settling with power:
1.
2.
3.
4.
5.
6.

Answer 5

1. Steep approach at a high rate of descent
2. Downwind approach
3. Formation flight approach (when settling with power could be caused by turbulence of preceding aircraft)
4. Hovering anode the maximum hover ceiling.
5. Not maintaining constant attitude control during an OGE hover.
6. During masking/unmasking
