Abstract:
An altitude profile representative of the terrain overflown by an aircraft is established. Thereafter, an altitude limit curve which comprises an intersection with the altitude profile upon the engagement of a terrain avoidance maneuver is determined. As soon as there is no longer any intersection of the limit curve with the altitude profile, the terrain avoidance maneuver is interrupted.
Abstract:
A method and device for aiding the piloting of an airplane includes: (1) determining current values of flight parameters of the airplane, (2) determining, with the aid of the current values, an approach distance that corresponds to a distance in a horizontal plane between the current position of the airplane and a position of contact with the ground, and (3) presenting the approach distance on a screen.
Abstract:
A method and device for determining the air turbulence likely to be encountered by a first aircraft may use a turbulence indication from a second aircraft so as to make and use a prediction of the impact of the turbulence on the first aircraft if it is located in a particular position.
Abstract:
The system (1) comprises means (3A to 3D) for detecting incapacity of the pilots to control the aircraft, and means (5) for automatically guiding and piloting the aircraft until it lands at an airport, on detection of such an incapacity.
Abstract:
A method for verifying the coherence of the takeoff parameters of an aircraft from an airport with an available runway length at the moment of takeoff comprises a step (E20) of identifying a takeoff runway and a step (E30) of validating the takeoff parameters with a view to authorizing takeoff of the aircraft if the takeoff distance is shorter than the remaining runway length associated with the identified takeoff runway.Use to make takeoff of an aircraft from an airport safe.
Abstract:
The inventive flight control assisting device comprises first means (4) for determining the actual aircraft flight conditions, second means (5) for determining, with the aid of said actual flight conditions and a predetermined pattern, a minimum approaching distance corresponding to a minimum distance between projections on the horizontal plane of the aircraft actual position and a touch-down point when said aircraft moves downwards and decelerates according to an optimised approach in such a way that stabilised approaching conditions are attained, and display means (7) for displaying at least said minimum approaching distance on a navigation screen (9) in the form of a first circular arc focused on a position relative to the aircraft which displays the touch-down position.
Abstract:
The invention concerns a terrain avoidance method and system for an aircraft. The system comprises a collision alarm device (3) and an auto-pilot device (5) including means (7) for determining a climbing order with optimal slope for the aircraft, means (12) for checking whether a first altitude gain at the relief, by applying the optimal slope climbing order, is sufficient for clearing said relief, means (11) for finding if there exists at least one heading variation value, for which the corresponding altitude gain is sufficient to clear the relief, and means (17, 22) for applying to the aircraft, if the first altitude gain is sufficient, an optimal slope climbing order with an order to maintain the current heading and, if the first altitude gain is insufficient, a particular climbing order sufficient to clear the relief, with a heading order which corresponds to the selected heading variation value.
Abstract:
System for aiding the piloting of an aircraft during the approach to a runway with a view to a landing. The system (1) comprises information sources (3) able to provide information relating to the aircraft and to its environment, a computation unit (4) which determines, with the aid of information provided by the information sources (3), an energy reference profile which preferably comprises a trajectory reference profile and a speed reference profile and which is intended to allow the aircraft to regain a stabilized approach trajectory, if it follows this reference profile, means of monitoring (7) for verifying that the aircraft is indeed following said reference profile, and means of indication (6) which supply the pilot with piloting indications at least to make it possible to pilot the aircraft in such a way that it always follows said reference profile.
Abstract:
According to the invention, a terrain avoidance maneuver is engaged when the alerts of a given pair of alerts are emitted simultaneously, the triggering of one of the alerts depending on the information provided by a first measurement chain and the triggering of the other alert of the pair relying on information provided by a second measurement chain, distinct from and independent of the first chain.
Abstract:
An aircraft guidance and piloting system automatically guides and pilots an aircraft in the event a pilot is unable to guide or pilot the aircraft. Upon determining the pilot's inability to control the aircraft, a processor transmits an automatic engagement command to a control unit. The control unit guides and pilots the aircraft to an alternative airport for landing.
