The CAA have a specific position in Air Operators Certificates known as "Operations Manager" which comes with distinct responsibilities. A friend thought outside the traditional line of operations manager with fixed wing operations and became a trainee operations manager for a large hot air balloon company. Not only did they eventually get to full time ops manager, but they were, in effect managing up to 14 aircraft going out both morning and evening with the relevant pilots and crew, but they were also answerable to the CAA on inspections, audits and their own paperwork. A recent advert for a trainee ops manager for a balloon company was advertising a salary up to £28k - considering they were offering to train you it seemed reasonable.
Some ops managers work two roles, UK in the summer and then head off to Africa or Australia to be ops managers in the winter for the balloon season over there....
