Device and method for monitoring the obstructions in the close environment of an aircraft
First Claim
1. A method to monitor an obstruction for an aircraft having a monitoring device, the method comprising the steps of:
- measuring location and identification parameters to locate and to identify the obstruction;
calculating identification parameters to calculate a location and a dimension of the obstruction, a direction and a speed of the obstruction, a distance between the aircraft and the obstruction, and a variation in the distance between the aircraft and the obstruction; and
generating audible and visual alerts to describe the location, a displacement and a criticality of the obstruction with respect to the aircraft, by calculation of an aircraft risk zone and an obstruction risk zone,wherein the aircraft risk zone comprises a volume disposed at a location corresponding to an anticipated location of a predetermined part of the aircraft, and the obstruction risk zone is located at a position of the obstruction and comprises the dimensions of the obstruction increased by a volume whose dimensions are dependent on a speed of approach of the obstruction and an anticipation time, and the audible and visual alerts are triggered when the obstruction risk zone penetrates the aircraft risk zone.

Abstract
The invention relates to a device for monitoring obstructions for an aircraft including data storage, an anticollision device and viewing devices, wherein the monitoring device comprises a detector to detect in real-time obstructions, of terrain type and of human constructions type, in a close environment of the aircraft in a flight situation, a sensor to identify the obstructions at risk calculating identification parameters, a circuit to calculate criticality of the obstructions, a display to display both the obstructions with the identification and criticality parameters of the obstructions, and a generator of alerts to describe the situation according to a combination of the identification and criticality parameters. One or more embodiments of the invention is a monitoring system adapted for zones close to the aircraft and in the flight zones not visible to the crew. One or more embodiments of the invention applies particularly to helicopters executing low-altitude flights. It relates more particularly to military carriers such as rescue carriers.
