I had a Med Board last year. As a result I was permanently grounded (NCA WSOp). The outcome of the board was very much based upon my wishes. I wanted to remain within the RAF, albeit on a permanent ground tour and with lots of restrictions on movement and employment. The President of the Board was of the opinion that discharging me just because I could no longer fly was a ridiculous idea as it would waste 25 years of experience and thousand of flying hours. I am now on an 8 year ground tour. Not everyones cup of tea I know, but at least the money is the same as when I was flying, subject to remaining in ground tours which have the Fg Pay marker on them. Best of luck for the future.
