Folks,
I have lost count of the dead trees used to publish "authoritative academic" studies on airline crew, I don't think any possible permutation has been missed. This one is more "high school project" standard, from what I have read.
Many years British European Airways, BEA (of non-landing handling pilot versus the landing non-handling pilot, not forgetting the non-landing non-handling pilot,fame) actually trialed the Captain sitting on the jump seat, with two F/Os having the window seats, it didn't last long, and was a schermozzle. As well as frightening Captains rigid.
As far as I am concerned, some of the best studies of how to organise a crew and sensible SOPs has come from Boeing funded studies, and it is fascinating to actually sit down with Boeing psychologists and other subject experts, and you can see the results in the changes/developments of Boeing flightdecks over the years and models.
Tootle pip!!
PS: BEA + BOAC = BA.
