1. A method comprising: at a transceiver located on an aircraft, generating reflectivity data based on an associated emission; at a processor, determining targets if a portion of the generated reflectivity data is greater than a predefined threshold; determining if the determined targets are within a dynamically defined three-dimensional envelope, wherein the envelope is based on wingtip light module speed and trajectory; and on a display device, presenting an indication of the nearest target at the associated range to the nearest target.
