Hi Simon. If your involvement in full size aviation was flight related you will already be very well prepared for the course and exam. The main difference between manned and unmanned (apart from size and payload
) is that you can operate much closer to the public in areas not segregated like full sized. The course is very public safety oriented rather than flight techniques, focussing mainly on the regulations around operating in UK airspace (minimum separation requirements from public etc) and a basic introduction to flight related topics such as weather, navigation charts,Human Performance limitations, all stuff you're probably already familiar with.
The more 'difficult' part is the Ops manual, which is to describe how you will operate. It is a tedious, difficult, frustrating, time absorbing medium to work on yet is a brilliant way to get an operator to really consider all the safety aspects of the business they are about to embark on and the responsibilities that go with the privilege of obtaining PFAW in UK airspace. It is also your chance to show the CAA regulators that you have the knowledge of the regulations and the method to work according to them. I took the course back in Oct 2013 and am here 8 months later (current work permitting) almost completed, but not quite there yet. Others have taken the course and completed in much less time so it's really down to how much time you can devote to it.
Enjoy the course.
Jim.
