During engine operation or starting, what is the minimum distance you must keep in front of and behind the aircraft?

• A. 25 ft in front and 200 ft behind
• B. 50 ft in front and 50 ft behind
• C. 10 ft in front and 100 ft behind
• D. 100 ft in front and 100 ft behind

Answer: (D)

Engines operating or starting create a strong jet blast and suction, plus potential debris being blown around. To keep everyone safe, a wide clearance around the aircraft is required, with a minimum of 100 feet both in front and behind. This distance puts you out of the main exhaust and intake zones and reduces the risk of injury from heat, blast, or flying debris as the engine spools up or runs at power. Shorter distances shown in the other options don’t provide enough protection for people standing or working near the aircraft.
