For the High Hover Practice Single Engine maneuver, what is the required surface condition?

• A. Rough, soft surface
• B. Gravel and dirt surface
• C. Smooth, hard surface
• D. Wet, icy surface

Answer: (C)

A smooth, hard surface is required. This provides a stable, uniform platform for the high hover with one engine running, minimizing debris in the rotor wash and avoiding surface irregularities that could affect control or cause damage. Rough or soft surfaces can throw rocks or dirt into the rotor system and airframe (increasing FOD risk and making handling less predictable), while wet or icy surfaces introduce slip and reduced control. Gravel or dirt surfaces pose similar debris risks and unpredictable interaction with the rotor wash. So a smooth, hard surface gives the safest, most predictable training conditions.
