Would'nt the introduction of this NPPL have been a good time to have introduced a standard medical for all recreational pilots. This could have been the same for all Class2,glider,microlight, balloon pilots etc? A basic declaration of fitness signed by your local GP who after all knows you far better than an AME or CAA doctor.Keep these for commercial flying but not for pottering around the local area in a Cessna.
Is there going to be some sort of guidance form to be issued that could be given to the GP. I'm sure there's likely to be some pilots who probably shouldn't be flying with condictions that could be spotted by their GP but are not notified to their AME's that they probably only ever see once every two to five years.
