title_body: Is there a list of milestones to check off before claiming one can "fly"
upvoted_answer: In the UK, the British Model Flying Association offer an Achievement Scheme which recognises a few levels of competence:
  
  
  The Basic Proficiency Certificates provide a measure of competence for pilots operating fixed and rotary wing aircraft fitted with
  stabilisation technologies.
  An FPV extension is also available to holders of any Basic Proficiency or ‘A’ certificate.
  The ‘A’ Certificate, which may be equated to a basic standard of safety and flying competence.
  The ‘B’ Certificate, which is designed to recognise a more advanced pilot’s increased ability and knowledge, and demonstrates a high level
  of safety.
  The ‘C’ Certificate, Aerobatics.
  The ‘C’ Certificate, Scale
  The ‘C’ Certificate, Gas Turbine
  
  
  As well as covering theory (air law/safety) questions, the flying skill required increases as the candidate progresses through the levels - from assisted flight, through holding level figure 8's and other manoeuvers, to being able to fly in aerobatic displays.
