AOPA has a far more realistic option for the future PPL instructor.....
Once the CAA gets off its backside and gets round to circulating the NPPL ANO amendment (it is now 34 months since the NPPL Policy and Steering Group agreed the proposal.....), the way ahead for the AOPA option will be clear.
This will effectively reintroduce the option for the rebirth of the PPL/FI qualification of yesteryear. 'Hours builders' could still exist - except that they would be able to 'build' before embarking on their CPL training provided that they had sufficient experience/aptitude to become FIs.
I agree that to 'upgrade' from FI(R) to FI should require a course and formal test as did the old UK AFI to FI requalification in pre-JAA times.
