Safety is the primary concern when flying sUAS in any airspace. Any tool that will aid in situational awareness should be utilized to enhance safety. As the airways get more congested with manned and unmanned traffic, technology such as ADS-B monitoring should be utilized.
The technology is available. It is just a matter of figuring out how to put it all together.
sUAS will not have ADS-B (Out) so it is vitally important to watch and listen for sUAS traffic on every flight.
Keep in mind that not all manned aircraft will have ADS-B (Out). If you are flying in Class G airspace outside of a Mode C veil, you will need to be diligent to watch and listen for manned and as well as unmanned aircraft.
