Engine Flight Cycle definition

Engine Flight Cycle means one take-off and landing of the Aircraft.
Sample 1Sample 2Sample 3
Engine Flight Cycle means, with respect to any Engine, one takeoff and landing of the airframe (including the Airframe) on which such Engine is then installed, provided that for purposes of determining cycles of utilization of a Part, the relevant “Engine” for purposes of the preceding clause shall be the engine on which such Part has been used during the period of such use.
Sample 1
Engine Flight Cycle or “EFC” is a flight which has a takeoff and landing, or a touch-and-go landing and take-off used to train pilots.

Examples of Engine Flight Cycle in a sentence

  • When this is impossible, due to over-stress of regions other than the critical location or stress reversal in the Engine Flight Cycle for example, the fatigue capability in operation should be established by an additional analysis.

  • The Engine Flight Cycle should include the various flight segments such as start, idle, takeoff, climb, cruise, approach, landing, reverse and shutdown.

  • For Rotorcraft turbine Engines, the representative usage of the 30-minute Power rating should be considered in the Engine Flight Cycle when establishing the Approved Life of each Engine critical part.

  • The range of ambient temperature and takeoff altitude conditions encountered during the engines’ service life as well as the impact of cold and hot engine starts should also be considered.The appropriatenessof the Engine Flight Cycle shouldbe validatedand maintained over the lifetime of the design.

  • Analytical and empirical engineering processes are applied to determine the engine internal environment (temperatures, pressures, flows, etc.) from which the component steady state and transient temperatures are determined for the Engine Flight Cycle.

  • The extent of the validation is dependant upon the approach taken in the development of the Engine Flight Cycle.
