What are the sources of pneumatic power? |
Engine 1 & 2 Bleed Air System APU Bleed Air System Pneumatic Ground Air Connection Pneumatic Manifold System |
|
|
How many engine bleed air systems are there? |
2, one for each engine. |
|
|
Engine bleed air comes from what? |
5th and 9th stage of the high pressure compressors. |
|
|
What does the pneumatic system supply? |
Hot, high pressure air. |
|
|
When does bleed air come from the 5th stage? |
High engine speeds |
|
|
When does bleed air come from the 9th stage? |
Low engine speeds |
|
|
What supplies bleed air on the ground and in the air? |
APU load compressor |
|
|
What does the pneumatic ground air connection do? |
Gives connection for ground pneumatic cart. |
|
|
The pneumatic cart can supply bleed air for? |
Engine start and ground use of the air conditioning system. |
|
|
What are the purposes of the pneumatic manifold? |
Send compressed air from pneumatic sources to user systems. Supplies a valve to isolate the manifold into two separate systems (left and right) Supplies connection for a ground source of pneumatic power. |
|
|
The pneumatic system supplies pressurized air to? |
Engine starting systems Air conditioning Engine inlet cowl anti-ice system Wing Therml Anti-Icing system Water tank pressurization system Hydraulic reservoir pressurization sys |
|
|
What does the air conditioning system control? |
Interior environment of the airplane. |
|
|
What are the subsystems of air conditioning? |
Distribution Pressurization Equipment Cooling System Heating Cooling Temperature Control |
|
|
What does the distribution system do? |
Divides AC to three airplane zones, reduces engine bleed requirements, removes offensive air from lavatory, and cools electronic equipment. |
|
|
What does the pressurization system do? |
Keeps cabin interior at a safe altitude (max: 8,000 ft) to prevent hypoxia (oxygen starvation). |
|
|
What are the subsystems for pressurization control? |
Cabin Pressure Control System Cabin Pressure Relief System Cabin Pressure Indication and Warning System |
|
|
What does the cabin pressure control system do? |
Controls rate that air flows out of the cabin. |
|
|
What does the cabin pressure relief system do? |
Fail safe system that protects airplane structure from over pressurization and negative pressure if the pressurization control system fails. |
|
|
What does the cabin pressure indication and warning system do? |
Gives data about the pressurization system status. |
|
|
What does the equipment cooling system do? |
Used cabin air to remove heat from electronics in the flight compartment and E/E compartment. |
|
|
What does the heating system do? |
Supplies warm air to areas to prevent freezing or to increase temp for comfort. |
|
|
What does the cooling system do? |
Controls quantity of air from pneumatic system to the pack, remove heat entering the pack, and controls output temp and moisture of the pack. |
|
|
What does the temperature control do? |
Control air temp in the flight compartment, forward cabin compartment, and aft cabin compartment. |
|
|
What is the oxygen system? |
Independent high pressure gaseous system in a cylinder in the EE compartment. |
|
|
How many high pressure oxygen cylinders can the aircraft carry and what is the capacity at normal temp and pressure? |
3-4 115 cubic foot |
|
|
The oxygen system provides emergency oxygen for how many people and how long? |
19 people for minimum 25 minutes. |
|
|
What oxygen system is found in the lavatory? |
One 4.25 cubic foot portable oxygen cylinder with a portable PSU oxygen mask. |
|
|
How many portable oxygen cylinders and what type are found in the mission compartment? |
Five 22 cubic foot with full face oxygen masks. |
