The position is for Flight Ops Manager, which includes Chief Pilot, Head of Training and Checking, Aircraft/ Flight crew scheduling and I would assume oversight of maintenance scheduling, preparation of flight ops budgets etc etc etc.
It's their ad, they can ask for what they like, at least they haven't demanded that you self fund a B200 endorsement if you haven't already got one !
