Aircraft Collision Avoidance Alarm
First Claim
Patent Images
1. An aircraft communications method comprising the steps of:
- collecting aircraft position information from a radar;
digitally encoding the aircraft position information in a first computer;
transmitting the digitally encoded information over a transmitter using a voice communications channel to aircraft;
receiving the digitally encoded information at an aircraft by a receiver;
decoding the digital information from the voice communications channel to determine if an alarm situation is present in a second computer; and
providing an alarm from the second computer if an alarm situation is present.

Abstract
The present invention provides an aircraft collision alarm system and method. The method includes the steps of collecting aircraft position information for aircraft in a given area and digitally encoding this aircraft position information. This aircraft position information is then transmitted on an audio sub-carrier over the voice communications channel of a VOR to the aircraft. The aircraft receives and processes the digitally encoded information and alerts the pilot if a collision alarm situation is present.
