A voice-activated system for interactive heads-up display (HUD) and control of traffic targets is disclosed. In embodiments, the HUD receives and decodes traffic information from onboard surveillance systems to identify proximate aircraft within a threshold range and the positions of each aircraft. The HUD arranges proximate aircraft into an ordered sequence based on distance from ownship or other priority criteria. When the HUD is active, interactive symbols are displayed at the positions of the proximate aircraft. A heads-up controller includes a microphone and switch operable by the pilot to signal incoming spoken instructions. The pilot can use voice commands to activate or deactivate the traffic overlay system or set parameters. Voice commands allow the pilot to highlight, select, and designate traffic targets for visual separation or other traffic applications based on the locations of traffic targets or by verbally identifying specific traffic targets.
