Which systems can pressurize the Potable Water System and what conditions must be met for the system to operate?

Answer 7

The Pneumatic System using bleed air from the engines or APU

An electric air compressor is used when the pneumatic system is insufficient and the following conditions exist:
- pressure in the water tank is less than 30 psig (pressure limit switch is closed)
- water service panel door is closed (compressor cut-out switch is closed)
- CAB/UTIL switch is positioned to ON

Question 8

When is 100% oxygen supplied to the Flight Deck oxygen masks?

Answer 8

By pushing the NORMAL/100% control lever, the regulator is adjusted from the air/oxygen mixture to 100% oxygen.

By Rotating the Emergency/Test selector, the regulator is adjusted to supply O2 under pressure.

Question 9

How is the PASS OXYGEN system activated?

Answer 9

With the switch in NORMAL, the system is automatically activated by an aneroid switch at a cabin altitude of 14,000 ft. When required, the PASS OXYGEN switch may be manually positioned to ON to activate the system.

Question 10

How long does oxygen flow when the PASS OXYGEN system is activated?

Answer 10

When any one of the four masks is pulled downward. Oxygen flows for approximately 12 minutes and cannot be shut off.

Question 11

What will cause the emergency exit lights to illuminate when armed?
