Well I for one am pleased that the NPPL is finally on the horizon - I too have eyesight which fails me for the JAR-PPL however I fly gliders quite happily and manage to see particularly well whilst doing so. This suggests to me that any "shock horror reduced fitness" arguments are slightly disingenuous. Why can I see perfectly well gliding but not in a 152? Yes eyesight is obviously important but I could hazard a guess that my corrected eyesight may be better than some flying who do not feel they need corrective lenses.
As an aside can I use any hours I have already (Powered and gliding) towards the NPPL?
