Intrigue
Thanks guys - I actually spoke to my instructor today and he agreed with Pace. It's certainly the cheaper option! But maybe I'll do the full thing when I get my licence or renew the medical or something.
Forget the cheaper option, while you are young and healthy spend the extra few pounds and have the full class one civil medical especially as you are considering a career in aviation.
The military use this principle as well, for example eye sight tests, if you go for your military medical and already wear glasses you are definitely going to fail for fast jet ops, if however you don't need glasses at the initial medical, then require them later in your fast jet training/career it's a different story, the civil medical is very similar, once you have the class one it's easier to keep it with medical issues than trying to get an initial medical with issues to start with.
