Answers are as follows:
1) HSBC, however you are free to raise the funds as you wish. I did not find the interest rate from HSBC very competive
2)I believe it is possible to raise further funds to cover the cost of living.
3)I am on the Jet2 TRSS, and that takes 55 days from start to getting the type endorsed on your licence, which is when you start getting paid.
4)Accomodation and full board is included while your are at CTC
5) The advanced handling course is to prepare pilots with no or little jet experience, for a jet type rating. It includes 1 day ground school and 5 days in the sim learning jet handling techniques. I personnally think it is an easy way for CTC to make money??
Hope this is of some help.
