The structure you suggest is in fact exactly what I had designed with CASA, and that is how our Exposition was written.
There was one AOC,.
There was one Exposition (Operations Manual .
There was one set of CASA approved Key Personnel..For redundancy there were two CASA approved Group CEOs, two CASA approved Group Head of Operations, and two CASA Approved Group Safety Managers.
The traditional CFI at each base stepped into the role of Senior Base Pilot.
One tailor made IT Learning Management System and Oversight system was developed covering every aspect of the business i.e. predictive maintaenace, safety bulletins, syllabi, profieciency checks, qualifications etc etc.
It was one "super school" with daily contact and weekly group meetings.
Cheers. Glen
