I have kicked this idea around a few times. If I wrote the ATPL syllabus it would focus on different things.
G-SXTY has alluded to one already, 3x table.
Rostering. How to maximise your flying for minimal effort.
Allowances. Ties in with rostering.
Contract negotiation. Use of Photoshop is a distinct advantage.
How to jump seniority queues. See skills with photoshop.
QRH and Checklist identification.
How to sound cool on the radio modules.
Offshore or onshore. Ties in with Contracts and allowances.
Human Factors. AKA don't screw the crew, also known as pilot error.
Every thing else is just padding.
