UAS Crewmember/Operator Requirements


The most important factor when selecting, certifying and training UAS operators is safety.  Having no onboard human on the aircraft adds a high degree of complexity to UAS. It is therefore very important to not only select the right crew members but also people who are detail-oriented and safety conscious. Many UAS accidents are caused by crew errors. Although many are as a result of Human interface systems in the Ground Control Stations, a few as also a result of improper flight operations procedures taken by UAS operators especially during takeoff and landing.
When it comes to the size and endurance of UAS, one has to look at the differences from military and civilian systems. Due to FAA restrictions, most civil UAS are either at or below the required 55 pounds. The bigger and longer endurance systems are used by the military. UAS technology development and the FAA’s efforts to integrate UAS into the National Airspace System is sure to blow open the limitations on payload and endurance for civil use. A good example is the Ikhana UAS that is being used to test Detect and Avoid technologies. When it comes to qualifications, most military UAS operators will rank higher since they have flown countless hours of UAS flights in training with flights in higher payload and endurance UAS systems.
Flight Training is an ongoing process. Although a pilot might be skilled on a particular UAS or system, there is still a need to continually train and refresh one’s knowledge especially as new technologies are being developed and imbedded into systems.

UAS Mishaps and Accidents


Many UAS accidents occur due to the Pilot error or inexperience with the UAS they are operating. Such accidents like the drone that injured an Australian triathlete, the UAS that flew into bystanders in Virginia crowd, and the UAS that flew into people attending a Bull run in Spain were as a result of lack of Pilot experience with the UAS or loss of situational awareness of the UAS they were flying.
Other drone pilots also seem to not understand the hazards of the UAS propellers. Another major issue affecting UAS operators is the issue of situational awareness and obstacle avoidance. Many crashes currently involving UAS seems to result from crashes with objects or into people. FAA PART 107 has enabled many operators to obtain the training and skill required for UAS operation but most often struggle to see and avoid obstacles and aircraft when operating drones at extended range, limiting their current operation to closed, line-of-sight environments.
As a result of the frequent crashes and accidents during UAS operation especially BLOS flights, it is necessary to equip UAS with GPS tracking and situational awareness onboard systems in order to reduce pilot/operator error, operational risk, and bring with it a trust that allows for scalability and use of truly autonomous vehicles (Iris, 2016)
