A 'Test' is done after a period of training. It is a Performance Standard check.
Training is a period of instruction by a suitably qualified person or persons.
I am not aware of any formal fitness training being carried out, by PTI's, at RAF units as part of the working cycle.
Therefore, the test is invalid because the training is non existent.
That makes it an administrative procedure only. Next time you are due to take the RAFFT, just send an e-mail saying you are fit.
If that is not accepted then we should shut Cranwell forthwith and tell all prospective Officers to learn how to be an officer in their own time. They can then report to their nearest RAF unit and sit an 'Officer Test'. If successful, collect your uniform and off you go. This could spread to flying training, ATC etc etc. We will save millions.
In short, if you want to test people, then train them. That means it becomes part of the working day. If there is no time then it is obviously not that important after all and should be ignored.
