Re: where to renew IR?
I renewed my FAA IR with a chap called Tony Gunn through Mid Anglia School of Flying at Cambridge. He is a freelance examiner who I believe does CAA as well as FAA renewals and works from several airports in the South. Good bloke.
I don't have a direct line for him but Mid Anglia will put you in touch, I am sure: 01223 294466
