I know of 3 FI's who all passed their Sim checks
I think that taking someone from zero hours and teaching them to fly is quite an achievement.
Perhaps it tells an airline that you might be interested in a future training role, could possibly handle a training role or perhaps you just wish to self-improve as an aviator...
Anyhow, 31, in a hold pool and doing the FI rating whilst I'm waiting.
