Way I heard it was.......
Before taking the tests you had 3 months of complusory PT 3 times a week.
Fail the tests 3 times after attending the PT and remedial - admin discharge.
Tests are not age / gender specific so the admin discharge rule can be applied without anyone cplaim sex discrimination
Currently about 80% are failing the tests in the trials being held at a Witlshire base. Hence the argument for the 3 months of compulsory PT.
To get round the lack of the muscle mechanics a number of people will be trained in each Squadron / Section to carry out circuits for their own section along the lines of the Army's unit PTIs.
Guess there is plenty of flex in the working day to allow for the 3 PT sessions a week and no one is working to full capacity already........
