Career as an Instructor
My thought
Pick a school with at least the option of work afterwards. Apart from the obvious reason you'll really benefit from the support and development of the structured environment. I'd been fly for twelve years when I started and couldn't believe the learning curve. Also try to get unrestricted doing weekend club work will take an age.
I reckon full time work would best be found at a commercial school. We only really want our guys full time... But here's kicker... Think of how're you're gonna fund for first 2 years at least. You can't live on people instructors money. My guys make about £10k pa. We ask a lot and offer little in return (harsh but honest).
You'll have to move up the chain. More experience, more tickets, etc. As a PPL CFI I can just about make ends meet. There is light at the end of the tunnel. CPL/ME/IR instructors do ok but it's a long time coming. I have no idea how guys how flying club instructors get by.
Steve Williams who does the FIC stuff at aeros in Gloucester is a good chap, go have a chat.
Sorry if this isn't as succinct as it could be. Long day in the air. I'll say one thing.. If you can put up with all the sh#t and don't mind not having a nice car or holidays it's the best job in the world. ;o)
