Question

When will the aircrew not attempt the tasks listed below?

1) When performance planning indicates OGE power is not available
2) When the hover power check indicates OGE power is not available
3) When both performance planning and the hover power check indicate OGE power is not available
4) When neither performance planning nor the hover power check indicate OGE power is available

Answer 1

3) The aircrew will not attempt tasks requiring OGE hover if both performance planning and the hover power check indicate that OGE power is not available.

Step-by-step explanation:

The correct answer is option 3) When both performance planning and the hover power check indicate OGE power is not available. In aviation, OGE stands for ‘Out of Ground Effect’ which relates to the increased power required for a helicopter to hover without the benefit of the ground effect.

Ground effect is a condition where the aircraft experiences increased lift and decreased aerodynamic drag when flying close to the ground, which typically reduces the power needed to maintain a hover.

In both performance planning and hover power checks, pilots determine if sufficient power is available to perform certain maneuvers, such as hovering OGE. If either process indicates that OGE power is not available, it is unsafe to attempt these tasks.

However, the most critical situation is when both planning and checks agree that OGE power is insufficient, which definitively guides the aircrew not to attempt the tasks requiring OGE hover.
