All members have a commitment to attain at least an “A Certificate” in the primary discipline area, i.e. Fixed Wing / Helicopter / Multirotor
However this does not restrict you from obtaining “A certificates” in as many areas as you wish.
An overview of the achievements scheme can be found here http://achievements.bmfa.org
To understand what is required of you in each skill area to pass the certificate you should review the documentation available on the BMFA website at this address
Skylarks members should login to the website to find contact details of all the groups examiners and any specific dates that have been arranged for taking certificates in the members area.
