DEVICES AND METHODS FOR FILTERING TERRAIN AN OBSTACLE ANTI-COLLISION ALERTS FOR AIRCRAFT
First Claim
1. Method for filtering anti-collision alerts for aircraft, the said aircraft comprising an alarm manager centralizing the alerts transmitted by terrain anti-collision equipment of the aircraft to the crew, the said alerts each possessing a coding of the danger level, the said danger levels forming part of a first predetermined set, the method comprising:
- a first step comprising the evaluation of the situation of the aircraft, the result of the evaluation giving an inhibition criterion authorizing or not the filtering of the alerts according to the crossing of predefined threshold values;
a second step of filtering alerts carried out by an alert filter capable of filtering sets of alerts according to the coding of their danger level, when the inhibition criterion permits the filtering; and
a third step of transmitting the unfiltered alerts to the alarm manager of the aircraft carried out by the alert filter.

Abstract
The present invention relates to a device and methods for filtering anti-collision alerts for aircraft having a locating system charting the position of the aircraft and estimating the precision of its position. A navigation system of the aircraft calculates at least the actual speed of the aircraft, the speed instruction and a first deviation between the instruction and the actual speed, and the deviation being compared with a first reference overshoot threshold. An anti-collision system generates alerts. An alarms manager of the aircraft centralizes the alerts transmitted by the terrain anti-collision equipment of the aircraft to the crew. The alerts each posses a coding of the danger level, and the danger levels form part of a first predetermined set. The alert filter according to the invention filters sets of alerts according to the coding of their danger level.
