1. A method comprising: at a transceiver located on an aircraft, generating reflectivity data based on an associated emission of signals; at a processor, determining a speed and a trajectory of a wingtip light module of an aircraft; determining dimensions of a three-dimensional envelope based on the speed and the trajectory of the wingtip light module, and based on predefined vertical boundary information; and determining targets if a portion of the generated reflectivity data within the dynamically defined three-dimensional envelope is greater than a predefined threshold; and on a display device, presenting an indication of a nearest target at the associated distance range relative to the aircraft by at least: generating, by the processor, a first range overhead display comprising an aircraft icon in response to determining the nearest target is farther than a threshold distance from the aircraft; and generating, by the processor, a second range overhead display comprising an aircraft icon in response to determining the nearest target is closer than the threshold distance from the aircraft.
