I really didn't want to get drawn into the money side, but.....
( now please consider before I begin - there are always two side - I am not elitist
)
I have banged on about IMC and R Nav in this thread, and the extra costs involved. englishal makes a similar point, in my humble. £600 in flying terms, over the license lifetime, is sod all compared with the price of hiring - Unless ....
If the extra ( compared to the existing ppl ) training is too expensive for an idividual, I would guess that there is a possibility that the individual would not be able to afford renting an A/C on a regular basis.
Does this itself not add to the problem?
I know I am generalising and presuming but the logic follows I feel.
