1. A method of managing a loss of power from a power plant of an aircraft, the power plant having three engines, each engine being capable of developing a maximum power (Pmax1, Pmax2, Pmax3) referred to as a “reference power” when none of the engines has failed,
wherein the method comprises successive calculation iterations, the aircraft requesting a power referred to as “useful power (Put)” on each iteration, the method performing the following steps on each iteration:
a monitoring step (STP1) for detecting a loss of power, during which each engine is monitored to detect whether an engine has suffered a loss of power, an engine that has not suffered a loss of power being referred to as an engine in nominal operation“, and an engine that has suffered a loss of power being referred to as an engine” in degraded operation”;a verification step (STP2) for detecting overpower, the power plant being “overpowered” when the power developed jointly by the engines in nominal operation is sufficient to reach the useful power (Put); anda signaling step (STP3) for:
generating a first alert when an engine has suffered a loss of power and when the power plant is overpowered, in order to signal a degraded situation in which the power plant is capable of delivering the useful power (Put) on the basis of its reference powers; andgenerating a second alert when an engine has suffered a loss of power and when the power plant is not overpowered, so as to signal a degraded situation in which the power plant is not capable of delivering the useful power (Put) on the basis of its reference powers, the second alert being different from the first alert. |
