The definition of an engine mount refers to the structure that supports the engine and is specifically designed to absorb engine vibrations. Engine mounts play a crucial role in maintaining the integrity and functionality of the aircraft while minimizing the transfer of vibrations to the airframe. This design helps protect both the engine and the airframe from potential damage and ensures a smoother operation.

They are typically made from materials that provide both strength and flexibility, allowing them to effectively dampen vibrations generated by the engine during operation. This damping is essential to reduce stress on the airframe and to maintain passenger comfort by minimizing noise and vibration levels inside the cabin.

In contrast, the other options describe different components or concepts not related to the function of an engine mount. For example, a system that controls fuel injection is essential for engine operation but does not pertain to structural support. Operating procedures for engines are guidelines or protocols for managing engine performance and safety but do not involve structural components. Finally, a device that measures engine power output works to assess engine performance but is not related to the physical support of the engine.
