DROPs also need knowledge and skills diff erent from
those of pilots. For example, they need to understand how wireless control links work, what can cause a link to be lost, and what responses by the DROP are appro- priate when the link is lost. They also need to acquire and demonstrate profi ciency in certain maneuvers and perceptual activities unique to microdrone fl ight where the operator is outside the aircraft. Flying from outside the cockpit is quite diff erent from fl ying from inside. For example, they must be profi cient in detecting a microdrone’s orientation is it fl ies further away and becomes less visible. They need to be able to use two-dimensional screen images of fl ight pro- fi les or a video captured by the ground, often called fi rst person view (FPV) by model aircraft hobbyists. They need to be good judges of height and distance, with or without the aid of telemetry from the micro- drone. Simply requiring that DROPs be licensed pilots is not the solution. What it takes to be a good airplane or helicopter pilot is quite diff erent from what it takes to be a safe microdrone DROP.
