CCS?
CCR?
CCS is Common Core System:
common computing network and data exchange for most airplane systems
CCR is Common Computing Resource, divides into left and right cabinets
CCS Startup sequence
Left CCR starts first, when battery switch pressed. It takes 2-3 minutes to come online. Left CCR is online when captain’s inboard and lower display show default pages.
Right CCR does not begin startup until left CCR sequence is complete, and a power source other than the battery is available (either FWD external power switch shows AVAIL). Both CCRs are online when all displays and the HUD combiners show default displays.
If CCRs operating normally, are there any controls or indications?
No. It’s all automatic.
CCR RESET switches?
CCR fault may result in the loss of displays. The switches can restore power to the displays, per the checklists in the EFB.
Heat source for OFCR?
Cabin Zone D duct. Temperature can only be increased from this duct temp.
Below what altitude does the OFAR have no ventilation?
15,000 ft

If switch held >30 secs, all lights that were illuminated PRIOR to TEST go full bright.
All displays windows on MCP blink for 2 seconds, then off for 1 second and repeat until released.
Passenger oxygen system type:
Gaseous oxygen stored in small high pressure cylinders, providing pulses of oxygen, shorter at low altitude, longer pulses at high altitude.
Oxygen available for approx. 60 minutes.
