Thanks for that, i do know i need to inform the medical side of things, and i did have a rough idea of the requirements i just wanted to know for definate.
And i am in the UK, and i have done the JAA exams.
I am going to be ringing up the CAA when i know the date of my operation for definate, and will probably have to go to the local checkup station to be checked over after i have healed.
