C-5/6 Console -- Range Safety System, Environmental Control and Life Support System (ECLSS), Environmental Control Systems (ECS), Power Reactant and Storage Distribution (PRSD) System

Several different functions are controlled at this console.

Key Positions: The Environmental Control and Life Support System (call sign CECL) Engineers command the environmental and life support systems on the orbiter. This includes pressurization of the crew module, distribution of potable water, maintenance of breathing air quality, and functional verification of the operation of the avionics cooling system throughout the vehicle.

The Fuel Cell/Power Reactant and Storage Distribution (call sign CFCP) Engineers control/maintain the devices which produce electrical power for the Shuttle by passing liquid hydrogen and oxygen over a catalyst in a strictly regulated operation. A byproduct of this function is pure water that provides the crew with all of their required potable water needs.

The Purge, Vent and Drain (CPVD) engineer controls all systems related to purging the orbiter such as conditioned air, gaseous nitrogen, and the operation of the 14 orbiter vent doors.

The Booster Range Safety Engineer (CBRS) is familiar with the destruct devices on the booster and external tank. This position monitors the health of these safety devices; the command to fire them in the event of a contingency would be given by the Air Force, which is responsible for range safety during Shuttle countdown and launch.
