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.

Method and device of terrain avoidance for an aircraft

Disclosed is a method and system for avoiding collision between an aircraft A and an intruder aircraft. The method and system involve determining avoidance presets to avoid a collision between the aircraft A and the intruder aircraft, in which the avoidance presets comprise a vertical speed preset. The presets are determined from avoidance information received from an anticollision system, and the determined avoidance presets are transmitted to at least one guidance device that guides the aircraft A based on the avoidance presets.

A method and device are provided for determining a target altitude for an emergency descent of an aircraft that is to be reached by the end of the emergency descent. The device determines an updated target altitude which takes into account variations of barometric pressure and which is able to replace the target altitude that must be reached at the end of the emergency descent. The method includes determining an initial target altitude representative of the initial position of the aircraft and then repeatedly determining a current target altitude along a reference horizontal distance. The current target altitude is compared to the initial target altitude and is used to update the emergency descent if the current target altitude is lower than the initial target altitude.

According to the invention, the device () comprises means () for detecting, during an altitude capture maneuver, the emission of a first type alarm by the anti-collision system () and means () for controlling the vertical speed of said airplane (AC), after the emission of such an alarm, until the triggering of the capture phase.

A method for automatically managing a lateral trajectory upon triggering an emergency descent includes determining a value of lateral offset and generating an offset setpoint by using the value of lateral offset. The generating an offset setpoint includes calculating a sum of the value of lateral offset and any initial value of lateral offset defined between a central axis of a protected sector that the aircraft travels along and an initial lateral trajectory. The offset setpoint is selected to be the smaller of the sum or a lateral offset maximum, which maintains the aircraft within the protected sector at all times. The aircraft is then operated to move the aircraft to the offset setpoint during the emergency descent, which helps avoid further air traffic that may be located at different altitude levels within the same protected sector, especially along the central axis.

According to the invention, the device () comprises means () for adapting the altitude capture maneuver, means () for first detecting the emission of a first type alarm, means () for determining a first alarm threshold and means () for establishing an activation height threshold from said first alarm threshold and airplane vertical speed at the time of the alarm emission, so that, when the height separating said aircraft (AC) from the altitude set level is strictly higher than said height threshold at the time of the alarm emission, said adaptation means () are disabled.

The invention relates to a method and device for limiting the number of alarms generated by an anticollision system on board an airplane according to which the duration of a phase of capture of a setpoint altitude by the airplane is adjusted so that a theoretical time for collision with an intruder aircraft is greater than a predetermined threshold, when the airplane is close to said setpoint altitude and air traffic exists in the environment of said airplane.

The invention describes a method and device for preventing useless alarms generated by an anticollision system on board an airplane and according to which the duration (dcap) of a phase of capture of a setpoint altitude (Zc) by the airplane is between a predetermined minimum execution deadline (dmin) and a predetermined maximum execution deadline (dmax).

A method and device are provided for determining a target altitude for an emergency descent of an aircraft that is to be reached by the end of the emergency descent. The method includes determining an initial target altitude representative of the initial position of the aircraft and then repeatedly determining a current target altitude along a reference horizontal distance. The current target altitude is compared to the initial target altitude and is used to update the emergency descent if the current target altitude is lower than the initial target altitude. Each target altitude is selected as the larger of a predetermined threshold altitude and a security altitude that ensures any obstructions along a remaining horizontal distance are avoided.

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.

A method and device automatically engage an emergency descent function of an aircraft as a function of pressure variation measured in the cabin of the aircraft.
