Wiggy,
You may, perhaps, be being facetious with your suggestion, but, as a Captain, I think it would increase my chance of sleeping from "no bloody way" to "yeah I might nod off" were it to be adopted.
My current ops involves moderately long 2 sector night ops with the "official duty" involving me "sleeping"
for a bit in Row 1-3.
Well,let me tell you, I don't, I do go back,so as not to ruffle feathers, and probably I never will manage to zzzz, so it is as well that I don't make too many of them in a month.
In God (& Pratt & Whitney, what about CFM?) we trust, the rest?
NFW ! !
