  • Patent number: 10822109
    Abstract: Aircraft and methods and systems for determining airspeed of an aircraft. The methods and systems allow for calculation of airspeed in near-ground and on-ground aircraft operation. A GPS altitude and a vertical acceleration of the aircraft are obtained for a current time frame. A geometric altitude for the previous time frame is determined, and the difference between the GPS altitude and geometric altitude are combined with the vertical acceleration to calculate a geometric altitude rate of change. The geometric altitude rate of change is used to calculate a pressure altitude rate of change, which is used to calculate a pressure altitude for the aircraft. A static pressure is calculated from the pressure altitude, and the airspeed is calculated using the static pressure.

The symbol is representative of a parameter associated with the dynamic behavior of the aircraft (FPV, . . . ) or liable to influence said behavior (FD, . . . ). The symbol possesses two components, and the first component is to be given precedence on display over the second component. In the method, the display of the symbol depends firstly on the orthogonal projection (FPV-lock) of the real position (FPV) of the symbol onto the axis of the first component, and secondly on the position of said projection relative to the display limit of the screen. Such a display makes it possible to give reliable information to the pilot.

Since a number of trajectory discrepancy factors will intervene during the lifetime of a flight, such as a change in flight intent, controller intervention, or large deviations of the actual flight from the predicted trajectory due to prediction errors, there is need to dynamically monitor these deviations and control a dynamic synchronization cycle. A dynamic trajectory synchronization algorithm attempts to bring each of the systems back into balance whenever a disturbance causes an imbalance.

  • Patent number: 8755954
    Abstract: A system and methods for generating alerts in a terrain awareness and warning system (“TAWS”) in an aircraft, using data acquired from a forward-looking radar The system comprises a forward-looking imaging device, an airport database, a navigation system, a forward-looking terrain alert (“FLTA”) processor, and a crew alerting system. The FLTA processor determines a measured clearance altitude of a highest cell within an area and compares it with a required minimum clearance altitude; if the measured altitude is equal or less than the required altitude, the crew is alerted. Alternatively, a terrain database may be used. with the FLTA processor for determining if the aircraft descends below the minimum operating altitude or is predicted to do so and then generating an alert. A method is disclosed for generating TAWS alerts using elevation angle measured by the forward-looking radar and terrain data retrieved from a terrain database.

  • Patent number: 8723695
    Abstract: A method for automatically detecting an erroneous height value supplied by a radio altimeter mounted on an aircraft. The method includes measuring, during the aircraft's approach phase with a view to landing, the duration between the times when a first predetermined altitude threshold and a second predetermined altitude threshold are reached. This duration is measured by taking into account current height values supplied by the radio altimeter. The method then includes comparing the measured duration to a predetermined duration reference time, which is lower than a flight duration that would allow the aircraft to descend from the first predetermined altitude threshold to the second predetermined altitude threshold at a maximum vertical speed. An erroneous height value is detected if the measured duration is lower than the predetermined duration reference time.

  • Patent number: 8723686
    Abstract: A method of managing an aircraft in flight may include electronically monitoring for a presence of a threat object along a flight path of the aircraft and at a destination airport of the aircraft, and electronically generating an alert when the presence of the threat object is detected. The alert may include information enabling air traffic control (ATC), flight dispatch, and a pilot of the aircraft to make a collaborative flight path correction decision that may prevent the aircraft from being affected by the threat object.

  • Patent number: 8681021
    Abstract: Present novel and non-trivial system, apparatus, and method for generating a lateral meteorological profile are disclosed. The system is comprised of a source for providing hazard data and a lateral profile generator (“LPG”), where the source could be comprised of an aircraft weather system and/or a datalink system through which hazard weather data is received. The apparatus is comprised of the LPG configured to perform the method comprised of receiving hazard data, determining profile location data, and generating profile image data. The hazard data represents location information of each hazard located outside the aircraft, the profile location data is representative of a plurality of locations of maximum vertical sector height within a vertical sector, and the profile image data is representative of a lateral meteorological profile comprised of a plurality of points, each point corresponding to one location of the maximum vertical sector height.

  • Patent number: 8660716
    Abstract: Methods, systems, and computer-readable media are described herein for providing comparative vertical situation displays of multiple flight routes. According to embodiments presented herein, information regarding a currently active flight route of an aircraft and one or more proposed alternate flight routes is combined with airborne constraint data to display a comparative vertical situation display for each of the active route and/or the proposed routes. Each of the comparative vertical situation displays shows the vertical component of the corresponding flight route along with the vertical components of one or more airborne constraints along the corresponding flight route. The comparative vertical situation displays are concurrently shown on a display unit, allowing the flight crew of the aircraft or route planning personnel to compare the impact of the airborne constraints along the vertical component of each of the flight routes.

  • Patent number: 8552888
    Abstract: A device calculates a first air speed representing an estimated air speed during flight using measurements of static pressure and total pressure onboard the aircraft. The device includes a storage device for storing in memory, in case of detection of a ground taxiing of the aircraft, the most recently determined value of static pressure corrected from induced aerodynamic effects. As a result, a second air speed representing the estimated air speed during the ground taxiing may be calculated by implementing a correction and using the most recently determined value of static pressure when the ground taxiing of the aircraft is detected. A method for automatically estimating an air speed of an aircraft is also provided.
