I got an NPPL a couple of years ago.
It was perfect for what I required.
Couldn't afford to do a PPL.
I'm an experienced glider pilot and instructor and my qualifications and hours counted towards reducing the number of hours required to obtaining the NPPL.
I had to fly ten hours to do it!
I happen to be a pilot with apptitude, awareness and ability and it was a breeze and all well within budget.
I now have a share in a smashing RF4 and couldn't be happier.
Cheap flying and aerobatics as well.
For some situations it's the perfect solution.
