There may well be more demand for the removal of the non-aerobatic restriction, following the CAA's latest clarification concerning aerobatics 'demonstrated' during 'trial flights' in Trainingcom 1/2005....:
AEROBATICS ON TRAINING FLIGHTS
We would like to remind you that the inclusion of any aerobatic manoeuvres during training flights constitutes aerobatic instruction, whether these manoeuvres are part of the training syllabus and the intended lesson or not. An Instructor is excercising the privileges of his/her FI rating throughout a dual flight (including a trial lesson) and to carry out or demonstrate any aerobatic manoeuvre, therefore, requires that the Instructor's FI rating is not restricted for the purposes of giving aerobatic instruction.
So - any of these 'aerobatic experience' trial flying lessons obviously require that the pilot must hold a FI rating which includes the privilege of instruction in aerobatics. Hitherto there seems to have been a misperception that 'demonstrating' aerobatics to a trial lesson 'student' was somehow considered to be something other than aerobatic instruction.
