I cannot let finance in which I would easily repay stand in the way of my career.
Go back to the bank with a plan of action for how you would repay the loan if you were unable to work as a pilot for 6 months or a year or longer. Do lots of research and give them a definitive guide as to how you will make them money, with your repayments. Remember that is the only thing a bank is interested in, making money.
Do this first before you go any further would be my advice.
