Paperwork while flying at cruise
Are you allowed to complete company related paperwork in-flight during cruise?
For example, my company has a needlessly long logbook form that is required to be completed for each leg. It takes about 3-5 minutes to fill out depending on maintenance requirements, although it's not any sort of intense calculus that requires 100% mental attention, just block times, block fuel, etc.
So in a transport category jet, stable cruise flight, would you be allowed to complete this paperwork or would you be required to transfer all pilot flying and pilot monitoring duty to the other pilot in order to do so?
Let's assume maximum formality, with an agent of your government's regulatory agency on the jumpseat observing. I realize that on a normal flight no one would care.
