Orion, um....I think I can speak to something you said about 'cramming 7 or 8 people into a B767 cockpit' and it getting stuffy. You see, I
actually used to fly the airplanes...and the B757, MD-8-, B737, DC-10 B727 and A-300. 22 years with a major US airline, so I believe I have a little
bit of credibility.
8 in a B767 would be pretty cramped, surely. However, 4 or even 5 isn't that bad. (This assumes that we're all getting along, and not trying to
cut the throats of the pilots with boxcutters...)
In addition to the Caption and First Officer seats there are two other jumpseats, one right behind the Captain (where the FAA or his designee will sit
when conducting in flight checks of the Captain since it provides a very good view of the forward instrument panel) and the other is starboard. Even
with four people up there, in each seat, there is enough space on the floor for one more, plus one could stand upright at the threshold.
Another thing...it would definately NOT get stuffy!! The airflow from the number 1 A/C Pack is prioritized to the Flight Deck, not only to ensure the
freshest air for the pilots, but also to provide sufficient cooling for all of the Avionics. Those CRTs get pretty warm...in fact, if you looked at
schematics from Boeing you could learn that for yourself. On the ground there are electrics fans that will operate, then they automatically shut off
in flight based on landing gear position (up or down), and temp sensors in the ducting, and the cooling relies on the outflow from the pressurization
system. IN fact, one of the many systems we have to learn about, besides fuel and electrical and power plant...is the E&E cooling system (E&E is
Boeing-talk for Electronic and Equipment, the magic stuff below the cockpit as well) since it is actually fairly complicated, though it operates
mostly by itself unless there is a malfunction that requires Pilot action. We have the yellow light, 'Equip OVHT', with a chime...and switches to
select 'Override' if needed...there is a whole page devoted to our QRH (Quick Refence Handbook) checklist just for equipment cooling.
I guess the point of this is: You must understand the reality of an airplane before talking about it as if you know, just from 'looking in' whilst
