At maximum thrust, the exhaust damage area is how many feet?

• A. 26 Feet
• B. 300 Feet
• C. 150 Feet
• D. 500 Feet

Answer: (B)

Exhaust damage area is the distance behind an operating engine where the jet blast and heat can cause damage to surfaces or pose a risk to people and equipment. When an engine is at maximum thrust, the blast is strongest and travels farther, so the safe zone must be large enough to prevent heat damage, paint blistering, structural effects, or injury to ground crews and nearby gear. For the CRJ-550, the established safety guideline sets that hazard boundary at 300 feet behind the engine. That’s why 300 feet is the appropriate distance to keep clear of the exhaust during max-thrust operations. The other distances are not aligned with the required protection level: they’re too short to account for the full jet-blast reach or reflect different, less stringent safety criteria.
