Anti-collision alert filtering device for e.g. helicopter, has alarm manger centralizing alerts transmitted by anti-collision equipments to crew, where each alert comprises danger level code, and alert filter filtering alerts based on code

摘要

The device has a localizing system for marking a position of an aircraft at each instant and estimating the precision of the position. An aircraft navigating system calculates real speed of the aircraft, speed set point and difference between the set point and real speed. An anti-collision system generates alerts e.g. sound alerts. An alarm manger centralizes the alerts transmitted by anti-collision equipments to crew, where each alert comprises a danger level code. An alert filter (1) filters the alerts based on the danger level code. An independent claim is also included for a method for filtering anti-collision alerts for an aircraft.
