CAT 1
The part about instructing is pretty interesting, I know 2 instructors who went looking for jobs, both had 2000+ hours of instructing. When they went to interviews at Ryan, GermanWings, Air Berlin the reqruiters didn't even bother to look at their SEP total time, the only thing that was interesting to them was their ME/IR and Turbine time... it wouldn't have mattered if they had 4000+ hours of SEP because it's all VFR and all slow speed SEP.
So back to stage 1, an instructor rating takes about 6-8 months to finish and costs about 14'000 Euro's today (including the cost of rent and food during those months of training), pay another 4 and you get a TR and start flying Turbine aircraft instead of having to sit right seat with pilots who doesn't even know what a glide slope is...
