Indeed, can you imagine the yearly SEP/SOPs on 3+ aircraft with all the variations as well....welcome to day 14 of the recurrent course!
And then you have all the galley, cabin and seating differences etc! Its hard enough having to think about 3 aircraft, with 5 differences sometimes! Especially when you get rostered different aircraft every day in the week.
Guess we're lucky to have the 3 limit rule in place?
