Avoid clearances that require Category ______ to taxi in proximity or hover-taxiing helicopters.

• A. H or I aircraft or helicopters
• B. A or B aircraft
• C. J or K aircraft
• D. C or D helicopters

Answer: (A)

The main idea here is safe separation during ground operations involving rotorcraft. Hover-taxiing helicopters are maneuvering very close to the ground with rotor systems turning, which creates unpredictable rotor wash and potential for collision or interference with nearby aircraft. To prevent such hazards, avoid issuing clearances that would require Category H or I aircraft to taxi in proximity to hover-taxiing helicopters. Those categories denote rotorcraft operations in close, low-altitude movement, where keeping clear of others reduces risk. Other categories described in the choices refer to fixed-wing or different rotorcraft contexts and aren’t the ones associated with hover-taxi scenarios, so they aren’t applicable to this situation.
