The invention is a sense-and-avoid display system that obtains position and/or velocity data for an unmanned aerial vehicle (UAV) and other aerial vehicles (AVs) from one or more radar and/or GPS data sources by wireless and/or wired data transfer pathways. The UAV and AV data are used to compute and display: present and projected future positions of UAV and other AVs; time and distance of closest approach between UAV and an AV; and recommended change in UAV's flight path and/or flight speed for conflict avoidance. This information is provided to the UAV pilot in 2D and 3D graphic displays.In standard mode of operation, UAV position and/or velocity data are obtained from UAV ground control station (GCS), while data for other AVs are obtained from a non-GCS data source (e.g., radar). In an alternative mode, UAV and other AV data are obtained from the same non-GCS data source. This alternative is an option when UAV is equipped with an identification device (e.g., transponder) and UAV is distinguished from other AVs using data obtained from an AV identification system (e.g., IFF).
