Im only pointing out the financial outlay concerned. We're away to hit a recession and fuel prices are at an all time high. Avgas is becoming very expensive, as are flying club rates. Not everybody has a spare 7 or 8 thousand quid to spend on a rating.
Im all for the 'experienced' PPL scenario however. I think its an excellent idea and i know of at least 2 people in my local syndicate who are interested. They both have 100's of hours and in my opinion would make excellent instructors. They are however put off by the price and the requirement to get the necessary time off work.
