The NPPL will also weaken the JAR licence.
I doubt too many people will cry if the JAR PPL eventually vanishes and we go back to national licences governed by associations like the PFA and recognised Europe wide. This will allow the flying for fun people to concentrate on amateur aviation and the budding ATPL’s to go down the professional route with JAR or whatever replaces it, + all the associated costs that will involve.
Question is how long will it take to happen?
