COLLISION AVOIDANCE TRANSPONDER FOR AERIAL HAZARDS AND METHOD FOR REDUCING COLLISIONS WITH AERIAL HAZARDS

摘要

Embodiments of a collision-avoidance transponder and method for reducing collisions with an aerial hazard are generally described herein. The collision-avoidance transponder may be configured for location on an aerial hazard and may be configured to regularly transmit a signal that mimics an air traffic control (ATC) transponder reply signal. The regularly-transmitted signal may include an altitude indication, such as the pressure altitude, of the aerial hazard. A collision-avoidance and warning system on an aircraft may receive the regularly-transmitted signal and provide a warning under certain conditions to allow the pilot to avoid the aerial hazard. The collision-avoidance transponder may include an ATC-type transponder and control circuitry to cause the transponder to regularly transmit the signal that includes a pressure altitude of the aerial hazard.
