Where exactly would all the extra money come from to cover their wages then?
An example of cost to student (Cessna 152) per hour
Aircraft hire £130
Instructor £25
So.. if the instructors fee is increased to £37.50 he/she has a massive 50% increase. The student however, has an increase in cost of only 8% - hardly noticeable. Quite possibly the club could even absorb some or all of this increase.
I feel students would also be happy to pay for briefings so long as the material was not what they would have already read in their PPL guides and was relevant to the lesson (obviously).
