METHOD AND DEVICE FOR ESTIMATING THE HEALTH CONDITION OF A DRIVE SYSTEM OF AN AIRCRAFT PROVIDED WITH AT LEAST ONE ENGINE AND A CLOGGABLE FILTER FILTERING THE AIR UPSTREAM

摘要

A checking method for checking a power plant of an aircraft, the power plant, comprising at least one engine and an air inlet, for feeding said at least one engine with air, the power plant including a cloggable filter filtering the air upstream from the engine. An aircraft power check is performed by: determining, in flight or on the ground, the current power actually being developed by the engine without making any allowance for any power losses resulting from the engine being installed in the aircraft or from a level of clogging of the filter, the aircraft power check being considered as being successful when the current power is greater than or equal to a guaranteed minimum power.
