Once you have done that, have a think about how you are going to improve your Maths (an 'E' at GCSE is woefully short of what a pilot needs) and English. You don't say how old you are, but I get the impression you have just left school. If that is the case, most employers will base part of their selection procedure on your academic history. If you are younger than 20 and have fewer than 5 GCSEs at Grade C or above, you will rule yourself out of many jobs. If you are contemplating a 'mentored' scheme such as CTC, you may well require 2 A-level passes. One or two schemes in UK are now suggesting that a degree is the minimum academic standard to enter, and that requirement may become normal in future.
You have a lot of work to do.
