You need to be able to earn in the region of 60-100k to be come a pilot without have to get shafted by the banks and not having to put your parents house on the line if it doesn't work out.
Now these jobs suggested get you into jobs which are pretty well payed from the word go. Engineering you tend to start off in the 25k range then it takes 5-10 years to get up to something which allows you to buy a house and save at the same time.
Now once you are training you will have to give up full time employement.
Both those jobs allow you to weekend work any days off for quite tidy sums while training and allow you to go back while looking for a job after training.
And Aero eng does not give you a huge advantage very little of what you will learn is relavent to pilot training. It is a very heavy maths degree and quite specialised. And if you really don't have a hunger to learn the subject its going to be very heavy going for you.
