1.1 ,This guide is intended for two distinct readers: educators who wish to develop curricula and training courses and individual pilots wishing to raise their knowledge level for particular flight operations. The guide describes the knowledge, skills, and abilities required to safely operate unmanned aircraft for commercial purposes. A Civil Aviation Authority (CAA) may, at their discretion, use this guide to aid the development of existing or future regulations. This guide addresses powered fixed-wing, vertical-take-off and lift and rotorcraft UAS and not other potential unmanned aircraft categories (for example, glider, lighter-than-air, etc.).
