General
Once you have a licence, if you only want to fly UK (G) registered aircraft in UK airspace then you can apply for a Pilot Medical Declaration (PMD) using the medical online system CELLMA
A medical declaration is an affirmation of your medical ‘fitness to fly’ and may be used to exercise the privileges of a qualifying pilot’s licence with certain conditions and limitations
Pilots must not make a pilot medical declaration if they do not reasonably believe that they meet the medical requirements for a Group 1 (Car) Licence issued by the Driver and Vehicle Licensing Agency (DVLA)
Further information on driving with a medical condition is available on the DVLA website
