Geoffers,
Also recall the requirements for the landing/takeoff and reject area...flat, smooth, etc. I doubt there are many "scene" flight locations that meet that requirement. Throw in night time and I would assume lighting becomes a requirement as well. So much for EMS flying in that part of the world it sounds like.
Does the CAA operate like the FAA....the definition of congested area can be construed to mean a single pedestrian or single motorcar if it is under the flight path of the aircraft? The Case Law is the final determining authority and not merely the regulation as printed.
