What is the standard width of a rotary-wing taxiway?

• A. 50 ft wide
• B. 60 ft wide
• C. 30 ft wide
• D. 40 ft wide

Answer: (A)

The main idea is to provide enough room for safe rotorcraft maneuvering on the taxiway. A width of 50 feet gives sufficient clearance for most helicopters’ rotor discs and tail rotor, plus room for comfortable steering and alignment during taxiing. This width also helps absorb the effects of rotor wash on the pavement and keeps the helicopter safely within the paved path while passing markings, signs, or nearby ground equipment. Keeping a consistent 50-foot standard across facilities makes it easier for pilots to transition between airports without adjusting expectations for space. While some very large or specialized rotorcraft might benefit from more width, 50 feet is the standard that balances safety and practicality in most operations.
