Which statement about helmet requirements is true?

• A. Helmets shall be worn with visors down or NVGs down within 100 feet of an operating aircraft
• B. Helmets shall be worn, with chin straps fastened
• C. Helmets shall be worn when pre-flighting above four feet for TH-73 aircraft
• D. All of the above

Answer: (D)

Helmet safety around rotorcraft operations requires protection in all relevant situations. Within 100 feet of an operating aircraft, helmets must be worn with visors down or NVGs down to shield the eyes from rotor wash, debris, and glare. The chin strap must be fastened to keep the helmet securely in place during movement or any unexpected motion. When pre-flighting a TH-73, helmets are also required if you’re above four feet, guarding against overhead hazards and tools. Because every one of these conditions calls for wearing a helmet, the correct statement is that all of the above are true.
