Thats a very valid point you make RTN.
The Instructors at EGNX work the Students hard to get down on the numbers and when I learnt their, we went up the road to Hucknall to bash the circuit to get the real world picture. PAPI approaches at EGNX were and still are not allowed at basic PPL level and rightly so.
No PAPIs at Barton nor Netherthorpe etc etc ad nauseum.........
