I suspect that in purely commercial terms Gertrude is correct, in that the club can decide on what terms they wish to conduct their business , just as I do in my own business.
However, I am completely behind Bose's philosophy on this one. GA is already grossly overburdened by unnecessary regulation which is strangling the life out of the industry,and shortly it appears to be made even worse by compulsory six yearly tests, with no perecived safety benefit from all of this regulation whatsoever.
The recent CAA review of safety statistics following the introduction of the new JAA requirements for biennial instructor flights, 90 day rules etc clearly showed no benefit whatsoever from the increased regulation, just more cost and disincentive for those who have already been through the exam and test mill.
I am lucky enough to have an instructor /examiner who is happy to let me bore holes in the sky in my own aircraft once every two years with no requirement for anything else, and long may that continue to be the case until my own choice and not bureaucracy states otherwise.
