The '25 mile' limit was removed because we agreed that it was unenforceable and would lead to concentration of aircraft in certain areas of the country leading to noise complaints and collision risk. Hence we split the final skill test into 2 - a general handling section and a navigation flight test. So, as currently proposed, the NPPL course is not that different from the pre-JAR/FCL PPL course. The only real extra in the JAR/FCL PPL is training in the use of radio navigation aids.
Examiners will not be accepting lower standards from NPPL applicants than they would from JAR/FCL applicants; if they're good enough, they'll pass. If not, they won't. It's up to the FIs and the training providers to make sure that their applicants are adequately prepared if they decide to put them in for their tests having flown just the minimum number of hours.........
