Which statement is true regarding helmet requirements?

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

Answer: (D)

All of the above statements are true, reflecting different ways a helmet is required to protect you in TH-73 operations. Wearing the helmet with the chin strap fastened is essential because it keeps the helmet securely on your head during movement, rotor wash, or sudden shifts in position. If the strap isn’t fastened, the helmet can come off or shift, leaving your head less protected. Having the visor down or NVGs deployed within 100 feet of the aircraft is about eye protection. Debris, wind, dust, and glare increase as you approach the helicopter, so keeping the visor or night-vision gear down helps prevent eye injuries and maintains visibility. Requiring a helmet when pre-flighting above four feet addresses head protection during elevated checks. When you’re working at height, there’s a greater risk of knocking your head on overhead components or losing balance; the helmet provides a safeguard in those moments. Together these rules cover head and eye protection across different phases of operation, which is why all the statements are true.
