'Red Cap' is a term often used in reference to the dispatcher. It harks back to the days when dispatchers, particularly BA wore red caps to differentiate them from other crew. Not sure if they still do?
Very first line of OMA (Admission to the flight Deck)
A) Admission to the flight deck is under the authority of the Commander.
That's all I need. Further more, although not categorically stated, it's my belief that, as Kennytheking states, the section 8.3.12 refers to in flight. Otherwise, why would part J, which refers to exiting the flight deck, be referenced alongside the other restrictions. That procedure certainly doesn't apply on ground.
