You, me may or may not like it but it is the way it is. It is not always the case that aerial work requires a CPL. There are many exemptions from that as you know. Such as Microlite Instructing, Glider Instructing, Glider Tugging and Parachute Dropping to give just a few examples. In fact a PPL Flight Instructor is still undertaking Aerial Work although unpaid. In France Flight Instruction is not included within the commercial sphere at all and the aircraft are not required to have a 'Public Transport' CofA.
Please realise that i'm not advocating any particular arguement but to vary the debate things are changing fast. Microlites are already very sophisticated machines and the VLA types are in already in operation. The NPPL take-up is growing with the SSEA class rating being the only NPPL rating that still requires the instructor to have a CPL to be paid. A few more years of statistics and that will change too. EASA themselves are proposing a 'Recreational' Licence, another name for our NPPL. The irony of all this is that Microlite Instructors are in the main paid better than Group A Instructors.
However, please don't turn this into yet another what have the romans ever done us thread
