I'd agree with KB and Scroggs for the most part. I'm practically ab initio on rotary and would like to go the whole hog to ATPL etc.
I made sure the finance was in place (well, most of it) before I started, and that was a struggle in itself. Now I know I can bail out at any time between £1000 and £50,000 should I need to and the only thing that will get damaged is the bank balance.
Irrespective of what anyone wants to do in life, my advice would be DO NOT RACK UP A MOUNTAIN OF DEBT. Large debts destroy peoples lives and people get into large debt very often because they will not accept what is staring them in the face - you can't do it or you can't have it.
I know that sounds very negative, but it's also reality. By all means borrow, but not until such time as it becomes an albatross that will weigh you down for the rest of your life. Scroggs is absolutely right.
It's like failing a Class 1 medical - doesn't matter how hard you want it, you have to accept the reality and work around it or with it somehow. The same is true of financing albeit slightly blurred at the edges.
