Chris, there is a great deal of information on this board about HSBC, Oxford Air Training, CTC and a host of other things that you need to know. Take a day or two (yes, I mean a day or two!) free of other activities to thoroughly research Wannabes. Then go away and think about what you have learned.
Some of the things you will need to consider (and will need to convince the bank that you've considered) are:
Why do I want to do this? What is it about flying a commercial aircraft that inspires me? Am I right in my preconceptions, or are my rose-tinted glasses a little too actively affecting my vision!
Where do I train? What are the advantages of one school over another? What is the end result that I require from that training? What qualifications does the industry expect of me as a newly-trained pilot?
How much does the training cost? How do I raise the money? What is the safest way to pay for my training that doesn't risk losing my money should the training provider fold? Who else bears a risk in my borrowing? What responsibilities do I have to them? How am I going to pay the money back if I don't get a flying job or, worse, fail the training?
What are the realistic prospects of employment? With whom? What are the current payscales for newly-hired, newly-qualified pilots? How long does it take to get to the kind of money I fondly hope they will pay me one day? Are my ideas of airline pay realistic?
What preparations have I made for entering the flying profession? What would a sponsor or future employer like to see in me? Where do I currently fall short of those characteristics or achievements? How do I rectify that? What are my fall-back options if I (or the industry) decide that flying's not the right choice after all?
What are my other ambitions? What are the chances of being able to achieve them while undergoing flying training, or while a pilot in (say) a low-cost airline? Where do I see myself in ten years' time?
Go through this lot and answer them honestly as you find (or already know) the answers. There will be more questions you will think of as you do your research, and you'll probably find that others have come up with them before you and discussed them here. When you've finished all this, come back to us with any questions that haven't been answered, and your thoughts about your future.
Good luck!
Scroggs
