Now I'm going to screw up this thread by adding number 4 (sorry Zap). This is maybe mostly a night freight thing, I suppose, but you pax guys do redeyes. How about letting the other guy nap in cruise. I was all for that. I was never much of a sleeper and would always offer to the non-flying pilot to take the radios and let them catch a nap. If I was really tired, and NFP, I'd ask if I could shut my eyes for 30 min. I can only mention this now that I'm retired....haha. This was was very commonplace at Brown as long as no management pilots were in the jumpseat.
