I cannot see how the NPPL is reverse snobbery. Please elaborate.
The RNAV and IF parts of the JAA PPL are somewhat problematic. It could be argued that its just enough knowledge to be dangerous.
When I did a PPL in 1991 I was not taught ADF or VOR at all.
Whilst more training is always welcome. Its a matter of what you can safely do without. The CAA and many many qualified Flying Instructors believe the NPPL syllabus contains all the necessary content commensurate with flight safety.
You will just have to trust that view I am afraid.
