Kermit's right, it hasn't been mentioned that it's actually three years; two years in CTC doing the main course, and then an extra year for the type rating. 3 years at £9k a year is £27k.
As Kermit says the extra £15k could come from maintenance loans, which until now I had forgotten were income dependant.
This leaves between £27-42k to find, not including the type rating. A lot more manageable than a flat £69k.
