What does RAT stand for in the context of fleet service?

In the context of fleet service, RAT stands for "Ramp Air Turbine." This term is used within the aviation industry to refer to a device that is deployed in certain scenarios to provide emergency power. The Ramp Air Turbine is typically utilized in situations where primary power systems fail or are insufficient, allowing essential systems to remain operational, especially during critical phases such as ground operations.

Understanding this terminology is important for personnel in fleet service roles, as they need to be familiar with the different systems and components that support aircraft operations on the ramp and during emergencies. The other options relate to various concepts that, while relevant to aviation, do not accurately represent the term RAT within the specific context of fleet service.
