Question on pilot / cockpit rules

fonecrusher1

In for example a medium size passenger aircraft like lets say a Boeing 737 are the captain and co-pilot ever for any reason permitted to be outside the cockpit at the same time while airborne. To be clear both of them not in their respective seats outside the doorway of the cockpit. Is this breaking flight rules?

Obviously excluding a medical / technical emergency that means they both have to vacate the cockpit

Not while airborne, no.

Must be two persons in the cockpit while airborne and if airborne a pilot cannot leave until a cabin crew member enters.

Obviously in the event of an emergency the rules go out the window and the captain can do anything required to obtain a safe outcome.

Goes without saying the cockpit door is to be locked any only opened per agreed procedure.

That’s airline specific. Not all airlines have this rule.

Physically remember that on many aircraft up to and including 737, there isn't enough space for the cabin crew member to enter FD before one of the pilots leaves the FD so the pilot will have to step out first before cabin crew enters but while keeping the door open.

I imagine the OP was prob on a flight with a 3rd or 4th flight deck crew member in uniform, whatever the purpose, training, line check, duty travel then of course 2 pilots may be seen temporarily outside the flight deck as the 3rd person will have to move out of the way to let one of the others out the door.
