For Mark in Idaho. I often hear that remark, "...video gamers can do this...". I answer with a qualified "Yes, IF". That is, IF the video gamer also posseses the collection of experience and knowledge, which might be called "airmanship", or "air sense", requiring intimate familiarity with the realm other requisite skills: navigation, airspace procedures and regulations, air traffic control coordination, communication protocols, weather interpretation and forecasting, systems operations, aircraft performance, emergency procedures, decision-making and judgement skills, crew resource management, ...the BIG picture on situational awareness. Our human senses contribute in many ways to completing this picture, and the designers of systems we're tasked to operate should account for the shortfalls that are unique to remotely-piloted aircraft. Flying is much more than eye-hand coordination.
