It is envisioned by the FAA that by 2016 UAVs will be flying in the NAS in fairly large numbers. There will be an increased need for TE potential hazards cannot be easily mitigated by aircrew action. Human factors and workload must be evaluated with respect to the envisioned mission, which may require long missions at remote sites. Communications are critical and the evaluation team must be cognizant of potential latencies, lost link, data rates, and volume. Changes to S/W must be approached even more carefully than with manned aircraft as there is really no second chance.
