Auxiliary Bridge

Auxiliary Bridge is a compartment on board a ship designed to replace the primary Bridge, in case the former is unable to fulfill it's functions.

Standard operating procedures call for the Auxiliary Bridge to be unoccupied and shut down under green conditions, at Condition Yellow (Yellow Alert) it's placed on standby with minimum staffing, and on Condition Red (Red Alert) it's fully staffed and ready to replace the main bridge at a moments notice.

It also is used in case of a mutiny or intruder alert where the primary bridge was under control of hostile forces and sealed off from the rest of the ship. To restore those connections for most ships requires a short stay at a repair facility.
