Aircraft avoidance method and drone provided with a system for implementing said method

摘要

A method enabling an aerial drone not having a TCAS system to avoid an intruder aircraft, the method including the steps of acquiring the position of the intruder aircraft in order to determine the distance between the aerial drone and the intruder aircraft, measuring the angular speed of the intruder aircraft in a horizontal plane, and determining whether the intruder aircraft is fitted with a TCAS system, and, if so, receiving a resolution advisory transmitted by the TCAS of the intruder aircraft and following a previously-determined avoidance path. The invention also provides a drone fitted with a system implementing the method.

1. A method enabling an aerial drone not having a TCAS system to avoid an intruder aircraft, the method is performed by a flight control system coupled with a data analysis system performing the following steps:
acquiring the position of the intruder aircraft in order to determine the distance between the aerial drone and the intruder aircraft; measuring the angular speed of the intruder aircraft in a horizontal plane; determining whether the intruder aircraft is fitted with a TCAS system, and, if so, receiving a resolution advisory transmitted by the TCAS of the intruder aircraft; determining the avoidance path after receiving the resolution advisory, wherein the step of determining an avoidance path includes a prior operation of analyzing the resolution advisory transmitted by the TCAS of the intruder aircraft in such a manner that if the advisory includes an order for the intruder aircraft to climb, the avoidance path comprises descent, and otherwise comprises a turn in a horizontal plane; and the aerial drone performing an avoidance maneuver according to the determined avoidance path to avoid collision with the intruder aircraft.
