The biggest hidden cost:
You can gain a JAA PPL with
a minimum of 45 hours. It is not guaranteed that you will achieve it in that time so be prepared to pay for more if necessary. We normally suggest 50-55 hours as a norm. The 45 hour minimum depends on good continuity (at least an hour a week - not an issue if you're doing it full time in one go), good weather (not a big issue in the USA, except in hurricane season
) and personal ability.
