Which statement regarding the idle, MIL, and max distances is true?

• A. They are all the same for intake and exhaust
• B. MIL distance pairs are 9 ft from intake and 115-155 ft from exhaust
• C. Idle, MIL, and Max distances: Idle 9 ft from intake/115-155 ft exhaust; MIL 25 ft/325-725 ft; Max 25 ft/850-925 ft
• D. There are no defined minimum safe distances

Answer: (C)

These distances are set to protect personnel from jet blast and heat during different engine power states, with closer clearances near the intake and progressively larger ones from the exhaust as power increases. Idle distances are 9 ft from the intake and 115–155 ft from the exhaust; MIL distances move to 25 ft from the intake and 325–725 ft from the exhaust; max power requires 25 ft from the intake and 850–925 ft from the exhaust. This pattern reflects how hazards grow with engine output, especially from the exhaust, so the statement that matches these exact figures is the true one. The other options ignore the variation between intake and exhaust or omit power-state differences, which makes them inaccurate.
