What does the Overheat Detection System (ODS) observe?
a. Engine bleeds and packs
b. APU bleed
c. Plumbing for the wing and engine anti-icing system
Is one detection Loop capable of detecting an overheat condition?
Yes (if one fails the other will work alone to detect the overheat)
How many ECS packs are installed?
2 independent packs (left and right)
Can a single ECS pack provide temperature control and pressurization?
Yes, but limited to operations at or below FL310
Can a single Bleed Source power both ECS Packs?
Yes, through the Crossbleed valve
How is the APU controlled?
Via a dedicated Fadec
What Battery is used for the APU Ground Start?
a. BATT 2 powers the starter
b. BATT 1 powers the FADEC and EICAS for monitoring
What does moving the APU start switch to ‘OFF’ do?
a. Initiates Normal APU Shutdown
b. Closes APU Bleed Valve
c. 1-minute cool down
Can a normal APU shutdown be canceled?
Yes, by moving the START switch back to ‘ON’ before the 1-minute cool down is over
How can you shutdown the APU immediately?
APU Emergency Stop button (no 1-minute cool down period
What will happen if the Batteries are turned OFF during the 1-minute cool down period?
APU will shut down immediately
When will automatic shutdown of the APU occur on the ground?
