Abstract
An assisted piloting method for an aircraft having at least two engines (2, 3) includes monitoring a set of parameters (Ng, T4, Tq) of the engines. A first limit indicator (10) displays information relating to a value of a limiting parameter of the engines. The limiting parameter is the parameter (Ng, T4, Tq) of the engines that is the closest to its limit. An assisted piloting mode is activated during which each parameter (Ng, T4, Tq) is maintained below a predetermined threshold whenever the first limit indicator is not in a position to display the information.
Claims17
A method of assisting piloting of an aircraft having at least two engines, each engine having a plurality of parameters (Ng, T4, Tq) and each parameter having a limit, the method comprising:
- displaying, from a first limit indicator for a pilot to view, information relating to a limiting parameter of said engines, the limiting parameter being the parameter amongst the parameters (Ng, T4, Tq) of the engines that is the closest to its limit;
- and
- activating an assisted piloting mode in which the engines are automatically controlled without pilot intervention to keep each parameter (Ng, T4, Tq) of the engines below a respective predetermined threshold whenever said first limit indicator is no longer in a position to display said information.
An assisted piloting device for a rotorcraft having at least two engines, each engine having a plurality of parameters (Ng, T4, Tq) and each parameter having a limit, said device comprising:
- a first limit indicator configured to display information relating to a limiting parameter of said engines, the limiting parameter being the parameter amongst the parameters (Ng, T4, Tq) of the engines that is the closest to its limit;
- and
- a control member suitable for maintaining the parameters (Ng, T4, Tq) of said engines below predetermined thresholds when an assisted piloting mode is activated upon said first limit indicator being no longer in a position to display said information.
A system for assisting piloting of an aircraft having an engine, the engine having a plurality of parameters and each parameter having a limit, the system comprising:
- a first limit indicator configured to display information relating to a limiting parameter of the engine, the limiting parameter being the parameter amongst the parameters of the engine that is the closest to its limit;
- and
- a controller configured to activate an assisted piloting mode in which the engine is automatically controlled to maintain the parameters of the engine below respective predetermined thresholds, which are respectively below the limits of the parameters, whenever the first limit indicator is unable to display the information relating to the limiting parameter of the engine.
