I have my doubts as to weather any bank would lend money for pilot training at the moment but you can only try I guess.
A sound business plan is required and know your stuff. Dress smart and be confident, keep your back straight and compliment the manager on his grey suit....sorry getting a bit carried away but you get the idea.
Wor is right that you will no doubt require a guarantor on any loan of say, 25k or more so get badgering those relatives!
Hope this helps.
