For deck heat mitigation, what should a V-22 with an operable Coanda exhaust deflector system do?

• A. Shut down immediately
• B. Retard over-deck engine toward idle within 10 minutes
• C. Accelerate to full power
• D. Re-engage all systems

Answer: (B)

The correct approach for deck heat mitigation when dealing with a V-22 that has an operable Coanda exhaust deflector system is to retard the over-deck engine toward idle within 10 minutes. This procedure is crucial because the Coanda exhaust deflector system helps redirect engine exhaust away from the deck, reducing heat buildup and minimizing the risk of damage to the deck or personnel. By bringing the engine power back to idle, the aircraft effectively lowers the temperature of the exhaust being expelled onto the deck. This action not only protects the deck surface but also enhances safety for crew members and any personnel on the flight deck. It’s an important step in maintaining operational safety and preventing heat-related hazards, which could lead to potential injuries or equipment damage. In contrast, shutting down immediately could lead to a sudden loss of power and capability, which may not be practical or safe in all situations. Accelerating to full power would exacerbate the heat issue instead of mitigating it, and re-engaging all systems does not address the immediate need to manage deck heat effectively. Therefore, retarding the engine is the most appropriate and safe course of action.
