Duty and rest under multiple regulators
An EASA crew operating into the UAE, repositioning under FAR 91, and then ferrying back via Saudi airspace can sit under three duty-time regimes in forty-eight hours. The dispatch sheet shows the most conservative limit at every leg, with the regulator that drives it named explicitly, so the captain does not have to do the comparison in their head at 02:00 local.
We track planned, projected and actual block times against the limit so the OCC sees the buffer shrink before it disappears. When the buffer drops below a defined threshold the trip is flagged amber and a positioning crew is offered before the captain has to ask.
