With over 2000 instructional hours would I be a likey candidate
The reason they originally set up their own FI Course was so that they could train their own instructors rather than have to retrain civilian instructors. They tend to prefer people with a military background as that's the environment you would be working in, and need to understand it. There is a marked divide between the Ex military instructors and the civilian instructors in the crew room, not necessarily a comfortable working environment. A good job if you fit in, but not a good place to be different.
