Within what distance must helmets be worn with visors down or NVGs down?

• A. 50 feet
• B. 100 feet
• C. 200 feet
• D. 500 feet

Answer: (B)

The rule tests protective eye/face protection in the rotorcraft operating area. When you’re within 100 feet of the helicopter or in the zones where rotor wash and debris are a hazard, helmets with the visor down or NVGs down must be worn to shield your eyes and face from wind, debris, and glare. That 100-foot boundary is the defined safety limit for this requirement. The other distances aren’t the specified threshold, so they don’t meet the rule as written.
