Abstract
A method for providing obstacle alerts to an in-flight aircraft has been developed. First, parameters of an in-flight aircraft are transmitted to a ground based processor station. The station calculates an aircraft safety envelope based on these parameters. The station accesses the characteristics of obstacles stored in a terrain database and calculates an obstacle safety envelope. Finally, the station determines if the aircraft safety envelope conflicts with the obstacle safety envelope and generates an alert for the aircraft if a conflict exists.
