Dear Chaps,
When bandying around figures such as £37,000 etc it will indeed seem like an outrageous amount of cash and will no doubt frighten a lot of wannabes. (Yes you're right it is a frightening amount!!!)
However, don't forget that going the modular route implies that it will be spent over a period of years. Think about your net income per year (that's after tax) and then multiply that by say 3 years. Now with a reasonable salary (£20k+ pa ???) that actually comes to quite a lot of money.
Obviously you will not live on fresh air so all living costs will have to come out of that but don't forget you can plan Birthday & Christmas presents to provide books/odd flights, you may get Air League Bursaries / Scholarships, your pay will rise, and you may take out a Career development loan.
I did the whole lot from 1 hour wannabe to CPL/IR in 2.5 years, and no I wasn't a whizz in the cockpit and yes I had to retake some of the navs etc.
I planned holidays and expenditure a long way in advance.
It's all possible just needs a little planning and forethought.
Bon chance.
