A multi-function avionics system that includes, but is not limited to, a combined traffic collision avoidance system (TCAS) and directional measuring equipment (DME) system that utilizes a multi-function directional antenna for both functions. The multi-function system utilizes the same directional antenna for TCAS and DME functions, which typically utilize the same communication frequency band. The multi-function antenna may include four antenna elements that discriminate the direction of the DME ground station squitter. The DME system establishes a bearing to the ground station from the squitter and uses this information to determine which directional beam to use for the DME interrogation. Directional DME interrogation reduces the power requirements relative to that required for omni-directional DME interrogation. The integration of DME and TCAS enables the removal of antennas and feeder cables from the aircraft, saving weight, drag and cost.
