FAA Private Pilot Helicopter (PRH)Navigation and AirspaceMedium
A helicopter pilot is operating over an open, sparsely populated area away from any structures, vehicles, or persons. According to 14 CFR Part 91, what minimum distance must the helicopter maintain from any person, vessel, vehicle, or structure?
- A1,000 feet horizontally and 500 feet vertically
- BThere is no minimum distance if operated without hazard to persons or property
- C2,000 feet horizontally at all times
- D500 feet in any direction
Show answer & explanationAnswer & explanation
Correct answer: B. There is no minimum distance if operated without hazard to persons or property
Under 14 CFR 91.119(d), helicopters may be operated at less than the minimums prescribed for airplanes if operated without hazard to persons or property on the surface, and in accordance with any routes or altitudes specified by the FAA.
Why the other options are wrong
- A. This describes congested-area minimums for airplanes, not the helicopter rule.
- C. There is no blanket 2,000-foot rule for helicopters under 91.119.
- D. 500 feet applies to fixed-wing aircraft over sparsely populated areas, not the helicopter exception.
Minimum Safe Altitudes (91.119) - Helicopter Exception
Helicopters are exempt from the standard minimum safe altitude rules if operated without hazard to persons or property on the surface.
- Airplanes: 1,000 ft above congested areas; 500 ft over other areas
- Helicopters may operate below those minimums if done safely
- FAA may prescribe specific routes or altitudes for helicopter operations
Memory trick: Helicopters get a 'free pass' from altitude limits as long as it's safe below.
