Problems solved by technology

[0009] However, the reduction in the vertical speed of the aircraft carried out when adapting to altitude change maneuvers results in prolonging the execution time of this adapting maneuver and thus increasing the time the aircraft spends between two altitude levels
[0010] Also, in some cases, such reductions in vertical velocity may also accelerate or result in TA and / or RA alerts

Embodiment Construction

[0041] exist figure 1 In , a device 1 according to the invention onboard an aircraft AC is shown in block diagram. Such a device 1 is used to prevent some TA and / or RA alarms from the on-board collision avoidance system TCAS2 of the aircraft AC while the aircraft AC is performing an altitude change maneuver for intercepting the set level Zc.

[0042]The aircraft AC is also provided with an autopilot system 3 that controls more specifically its vertical velocity Vz. The automatic navigation system 3 may include at least some of the devices 5 to 8 of the apparatus 1 described later.

[0043] In this figure, the anti-collision system 2 and the autopilot system 3 are shown outside the aircraft AC, while they are actually installed on the aircraft.

[0044] As known, the anti-collision system 2 is capable of detecting an intruding aircraft AI in the air environment of the aircraft AC, to calculate a theoretical collision time between the aircraft AC and said intruding aircraft AI...

Abstract

According to the invention, the device (1) comprises means (4) for adapting to altitude change operation, means (5) for firstly detecting the issuance of a first type of alarm, means (6) for determining a first alarm threshold and Means (7) for determining an activation altitude threshold from said first alarm threshold and the vertical speed of the aircraft when the alarm is issued, so that the altitude separating said aircraft (AC) from the altitude set level when the alarm is issued is strictly high At said height threshold, said adaptation means (4) are disabled.

Description

technical field [0001] The present invention relates to a method and a device for preventing an on-board collision avoidance system of an aircraft from sounding an alarm during altitude change maneuvers, and to an aircraft provided with such a device. Background technique [0002] As is known, most aircraft are equipped with a collision avoidance system (often called TCAS, Traffic Collision Avoidance System T raffic C ollission A void S systems), which allow to ensure the safety of air traffic, preventing the risk of in-flight collisions. [0003] Thus, when two planes cross each other, their collision avoidance systems calculate an estimate of the time to collision and issue an alert alerting each plane's crew of a possible future collision: such alerts are often referred to as Type 1 "traffic Notification" or "TA Alert". If applicable, the collision avoidance system further issues avoidance maneuvers in the vertical plane in order to get the crew's attention, in order...
