Do not park or drive within how many feet to the rear of the aircraft?

• A. 100
• B. 300
• C. 400
• D. 200

Answer: (D)

The main idea here is keeping yourself out of the danger zone created by the aircraft’s exhaust and rotor wash. The rear of an aircraft can produce a strong blast that can throw debris, knock people off balance, or damage nearby equipment, especially when engines are started or at high power. To provide a safe buffer, the minimum recommended distance for parking or driving behind the aircraft is 200 feet. This distance gives enough clearance for the blast to dissipate and for pilots to maneuver without threats from vehicles or personnel behind them. Choosing a shorter distance, like 100 feet, would not reliably protect you from engine start or reverse thrust effects. A larger distance, such as 300 or 400 feet, isn’t necessary for the typical minimum safety standard and would complicate ground operations more than needed. The 200-foot rule is the practical minimum to balance safety with efficient operations.
