Aircraft collision avoidance system

An aircraft collision avoidance system configured for mobile use with a plurality of aircraft during ground transportation, comprising:

• at least one separation monitoring device releasably positionable on at least a portion of an upper surface of at least one of a wing and a horizontal stabilizer of an aircraft, the separation monitoring device comprising:
• a housing for containing at least one wireless transceiver and an energy source;
• wherein the at least one wireless transceiver transmits ultrasonic signals and receives ultrasonic signals which are reflected back to the wireless transceiver off of an object in order to define a separation distance between the wireless transceiver and the object and wherein the wireless transceiver outputs a separation distance signal representative of the separation distance;
• and
• wherein the energy source is contained within the housing and provides energy to the at least one separation monitoring device;
• and
• a master unit for receiving and analyzing the separation distance signals output by the wireless transceiver, the master unit outputting a warning signal to a warning device when the wireless transceiver is within a predetermined distance from an object.
