Thrust reversers are categorized under which ATA chapter?

Thrust reversers are categorized under ATA chapter 78, which specifically deals with "Engine Exhaust and Thrust Reversal." This chapter encompasses various aspects of engine design related to the management of engine exhaust, including the mechanisms used to divert thrust for the purpose of deceleration during landing. Thrust reversers play a critical role in enhancing safety during landing by allowing an aircraft to decrease its speed more effectively on the runway.

Understanding the purpose of ATA chapters is essential, as they are organized by systems and components within the aviation industry, helping technicians locate and manage technical manuals and maintenance procedures efficiently. While other ATA chapters cover different systems such as engines, airframe, or other components, ATA 78 is distinctly focused on the specifics of thrust reversal systems and the associated technical requirements.
