Thrust reversers are categorized under which ATA chapter?

Thrust reversers, which are devices used to redirect the engine's thrust to slow down an aircraft upon landing or during certain phases of flight, are categorized under ATA chapter 78. This chapter specifically addresses "Engine Indicating and Crew Alerting Systems," which includes systems essential for operational safety and efficiency related to thrust management. Understanding this categorization is crucial for maintenance and operational procedures, as it helps professionals locate pertinent information efficiently in the context of aircraft maintenance and repair manuals.

The other ATA chapters mentioned do not cover thrust reversers and relate to different aspects of aircraft systems. For instance, chapter 72 covers "Engine Fuel and Control," while chapter 74 addresses "Nacelles, Pylon, and Engine Mounts." Chapter 76 deals with "Engine Indicating and Crew Alerting Systems," but does not encompass the specifics of thrust reversers, which is why the correct categorization rests in chapter 78.
