As one who is at the stage of sending out CVs when appropriate, I cannot agree more with BelArgUSA.
If you have ever worked in the
real world you may have a totally different view on how CVs should be prepared, but as far as I can tell the Aviation industry is very unsophisticated in this regard. All the Chief Pilot cares about is your flying experience. Your 18 Cub Scout Badges don't count. Sadly. So, keep it short!
Low hour pilots might not even be able to fill a whole page with relevant information so in my opinion you can add a little personal information to give a flavour of your personality. After all, you've so little else on your CV to mark you out from the other 19,301 applicants that you might as well mention your Airfix hobby. You never know, the Chief Pilot might also be an enthusiast...
