ABSTRACT:
An aircraft upon approaching a runway for a landing receives a "measurable signal" from a transmitter located at the far end of the active runway. The strength of this "measurable signal" is indirectly proportional to the distance between the aircraft and the transmitter. After this signal strength is converted to digital data, a computer uses this distance in conjunction with preprogrammed performance characteristics of the aircraft to make a "safe" or "unsafe" decision. This decision is communicated to the pilot by means of a special meter on the instrument panel. The "safeness system" may be coupled to the aircraft's automatic braking system to provide a correct amount of deceleration. If properly enabled, this "safeness system" will initiate a go-around for another try at the landing should the current landing attempt be unsafe. A similar procedure would also abort a takeoff should the aircraft not reach rotation speed in time to clear an obstacle at the end of the runway.
