I'm 31 and have decided to start an integrated course in about 12 months time (next Oct). I have lots of options open, but due to my age, the age when I will 'graduate' I feel the integrated option is more suitable for me. I already have a PPL, night and IMC, but feel the integrated course will be the added bonus for me. I've been out of Uni for a long time, and want the atmosphere of the integrated course to get me through.
I will tag on an instructors course at the end, and fully expect to be a instructor for more than 12 months, but should then have reached something in the region of 800 hrs in order to get my first flying job (which will be when I'm about 34/35). That's 20 years for the career.
