What is the term for the operational checks conducted on engines during powerplant inspections?

The term for the operational checks conducted on engines during powerplant inspections is known as functional checks. These checks are crucial as they ensure that the engine operates correctly and safely under normal operating conditions. Functional checks typically involve tests on various systems and components, including fuel delivery, ignition, and engine performance parameters, allowing technicians to verify that everything is functioning as intended.

While visual inspections focus on the physical condition of the engine components and performance evaluations assess the overall performance metrics of the engine, functional checks are specifically aimed at confirming the operational capabilities of the engine systems. Operational assessments generally cover broader operational aspects rather than the specific functionality of engine components. Hence, functional checks represent the precise checks conducted to determine if the engine meets operational specifications and safety standards during inspections.
