IRCM tow from hangar: If aircraft is equipped with Infrared Countermeasures (IRCM), the IRCM system shall be returned to service after task completion.

• A. True
• B. False
• C. Not specified
• D. N/A

Answer: (A)

The key idea here is that protective systems on an aircraft are kept ready for flight and threat protection after any ground handling or maintenance. Infrared Countermeasures (IRCM) are part of that protection, so once the tow from the hangar is finished, the IRCM system should be returned to service to ensure the aircraft is prepared for its next mission and protected if a threat arises. This maintains aircraft readiness and avoids leaving a protective system disabled when the aircraft is soon to fly.

Leaving the system out of service would undermine readiness and protection, and stating that it’s not specified or not applicable doesn’t align with standard maintenance practice of restoring systems to their flight-ready state after handling.
