  • Patent number: 11556138
    Abstract: A piloting assistance system for an aircraft includes a measuring module for measuring a vertical manoeuvre of the aircraft, a computational module for computing a first load factor from the measured vertical manoeuvre and from a setpoint vertical manoeuvre, a measuring module for measuring an inclination angle, a pitch rate and a pitch acceleration, a protection module including a computational submodule configured to compute a second load factor and a comparison submodule in order to compare the first and the second load factor in order to determine an applicable load factor equal to the minimum between the first and the second load factor, a computational module configured to compute elevator control from the applicable load factor and a sending module configured to send the elevator control to the automatic pilot.

  • Patent number: 10802039
    Abstract: An estimation system includes a module for measuring a current angle of attack and current flight parameters of the aircraft, a module for estimating a current lift coefficient of the aircraft from the current flight parameters and from a mass of the aircraft, a module for estimating an angle of attack for a zero lift from the current angle of attack, from the current lift coefficient and from a slope of an affine part of at least one theoretical curve describing a lift coefficient of the aircraft as a function of an angle of attack, a module for estimating the current position of the flaps of the aircraft from the angle of attack for a zero lift and a module for sending the current position of the flaps to a user device.

  • Publication number: 20190197906
    Abstract: A piloting aid system for ensuring the availability an automatic pilot corresponding to an automatic piloting system and/or a flight director and/or a thrust regulation device to be controlled as a function of a speed information item determined from a source of information, and configured to operate according to a first current guidance mode and an approach capability that are part of a first set of guidance modes and approach capabilities. The system includes a surveillance module to be able to detect the loss of sources of information, a module for determining a second set of guidance modes and of approach capabilities as a function of the source or sources of information whose loss was detected by the surveillance module, a module for use, by the automatic pilot and/or the thrust regulation device, of a second current guidance mode and an approach capability that are part of the second set.
