At Idle Thrust, the Exhaust Damage Area is how many feet?

• A. 50 Feet
• B. 100 Feet
• C. 150 Feet
• D. 200 Feet

Answer: (B)

Exhaust Damage Area is the safe zone around an engine exhaust where heat and hot gases could cause damage to people or nearby equipment. At idle thrust, the exhaust output is lower, but there’s still enough heat to warrant a defined clearance. That’s why the standard distance is 100 feet—it provides a practical safety buffer during idle engine operations without being overly restrictive. A shorter distance would risk heat damage or flame exposure to nearby surfaces and gear, while larger distances are typically reserved for higher engine thrust settings or special operations. So keeping a 100-foot separation during idle aligns with safety guidelines for ground operations.
