I don't have the details with me right at the moment, but have a word with the flying schools themselves. However, as far as I know, the JAA regulations have affected the 501 course as compared with 12 months ago. It's now less hours (but still the same cost (?))
Flight Safety still offer a 501.
OATS and Cabair offer a joint CAA/JAA
Everyone, except Cabair, are on the WWW to get phone numbers and details from.
