That's true but it is getting very hard now to avoid modern avionics when doing the FAA PPL, because most schools have modernised, and the examiner will request a demonstration of competence on all installed equipment (to the extent compatible with the license privileges i.e. no need to demonstrate GPS approaches when doing the PPL
).
Whereas in the UK, any installed GPS is turned off during the skills test, and probably during all the training (at most schools, anyway, even though a GPS can be used in most of the PPL syllabus).
Anyway, the length of this thread shows how much negative impact a silly little one-liner in what purports to be an official organ of the CAA can have.
