C-9/10 Console -- Hazardous Gas, Instrumentation and Electrical Power Distribution and Control (EPDC)
Systems both on the Shuttle vehicle as well as supporting it are controlled and monitored at these console stations.
Key Positions: The Orbiter Instrumentation Engineer (CISL) and systems engineers maintain and control the validity of Shuttle telemetry and instrumentation used for vehicle processing. They also maintain and monitor the on-board caution and warning electrionics assembly, which provides the flight crew with visual and audible indications of out-of-tolerance conditions for selective flight-critical measurements. They also perform checkout and maintenance of the flight recorders which store orbiter instrumentation data, payload data and modular auxiliary data during the mission.
The Hazardous Gas System Engineers (CHGD) monitor the detection systems for hazardous concentrations of hydrogen, hypergolic fuels and various items of fire detection equipment. These are located on board the vehicle as well as on select ground support equipment.
The Electrical Power Distribution and Control System Engineers (CEPD) control and monitor electrical power distribution to the orbiter and payload buses and perform testing of the orbiter pyrotechnic devices.
The External Tank/Solid Rocket Booster (ET/SRB) Electrical System Engineer (call sign CPWR) controls and monitors electrical power distribution to the SRB joint heater and external tank heater systems and performs testing of the SRB recovery system and SRB pyrotechnic devices.
