COMMAND STATIONS

	The Main Bridge command stations provide seating and information 
displays for the Commanding Officer (normally the captain) and two other 
officers, typically the First Officer and the counselor. The command stations 
are centrally located, designed to maximize interaction with all key bridge 
personnel, while permitting an unobstructed view of the main screen.
	The captainÕs chair features armrests that incorporate miniaturized 
status displays, and simplified Conn and Ops controls. Upon keyboard or 
vocal command, the captain can use these controls to override the basic 
operation of the spacecraft. Such overrides are generally reserved for 
emergency situations. The other two seating positions in the command area 
include somewhat larger information display terminal screens, which permit 
these officers to access and manipulate data as part of their duties.
	Cruise Mode operating rules require a shift Commanding Officer to be 
on duty at all times, although the presence of other command personnel is 
optional, depending on specific mission requirements. Yellow and Red Alert 
operating rules generally require the presence of at least two command 
personnel, in addition to Conn and Ops.  Æ
