Abstract
An intuitive display including a visual representation of a maximum admissible angle of attack on a pitch scale giving the crew of an aircraft a visual recognition of an imminent stall, or of a stall, together with real assistance with piloting during the stall until the aircraft has come out of the stall completely.
Claims12
A method to assist piloting of an aircraft, according to which a trajectory pointer representing a current flight trajectory vector and a pitch pointer indicating a current pitch angle value are shown on a pitch scale of a display screen, including the following steps:
- determining a pitch angle limiting value representative of a maximum admissible angle of attack, depending on a set of flight parameters and aircraft configurations, and
- displaying on the pitch scale of the display screen a maximum angle of attack pointer indicating the pitch angle limiting value, where the maximum angle of attack pointer and trajectory pointer form upper and lower limits, respectively, of a dynamic safety envelope representative of a normal flight of the aircraft.
A system to assist piloting of an aircraft, including a display screen showing a pitch scale, where a trajectory pointer represents a current flight trajectory vector and a pitch pointer indicating a current pitch angle value, comprising:
- calculation means to determine a pitch angle limiting value representative of a maximum admissible angle of attack, depending on a set of flight parameters and aircraft configurations, and
- calculation means to display on the said pitch scale of the display screen a maximum angle of attack pointer indicating the said pitch angle limiting value, where the said maximum angle of attack pointer and trajectory pointer form upper and lower limits, respectively, of a dynamic safety envelope representative of a normal flight of the aircraft.
