Sovereign Pneamatic System Flashcards
What systems require Bleed Air to function?
- Service Air
- Ice Protection (cowl,stator,horizontal stab,wing)
- Air Conditioning
- Pressurization
- Baggage Heat
- Rudder Bias
What Systems Bleed Air require pre-cooling prior to use?
Environmental
Wing and Stab Anti-ice
Service Air
What does the NORM position on the BLEED AIR Panel do?
Provides LP Bleed and HP Bleed augmentation depending on demand and TLA position
Which throttle will cause the acoustic seal to deflate?
Left throttle to Cutoff
What are the 6 zones of the Bleed Air Leak Detection System?
Wing L/R
Bleed Supply L/R
Stab Anti-ice
ACM
What Systems use Service Air?
Acoustic Door Seal
Vacuum Ejector for the control of the Outflow Valves
and on older models Rudder Bias Heat
In what position do the Mass Flow Valves fail?
Open
How can you test the Bleed Leak Detection System?
Rotary Test
Where does the Bleed Air for the Baggage Compartment come from?
The Left Engine via the Left Mass Flow Valve
Does anything happen automatically when a Bleed Leak is Detected?
Yes, respective zones are isolated automatically
From which stage is LP discharged?
P2.5
From which stage is HP discharged?
P3
How do the HP valves fail with loss of Main DC Bus power?
Open
How can pilot control HP or LP Bleed?
Automatically via TLA or Manually on the Bleed Air Control Panel
At what temperature is the Baggage Compartment heated?
70 to 100F
What does the Mass Flow Valve do?
Controls Bleed Air flow to the ACM
What is the APU Bleed Air used for?
Environmental and Service Air
What happens when you move the Pressure Source Selector to OFF?
Closes the Mass Flow Valve
Can you affect Engine Anti-ice by moving the Engine Bleed Air Selector to OFF.
No
Can you use HP and LP at the same time?
Check valves prevent it
What is a Bleed Air O’TEMP usually an indication of?
Problem with Pre-Coolers
When will the EMER Pressure be activated?
- Manually
- ACM O’TEMP
- ACM Bleed Leak
- Cabin over 14,500
What’s the purpose of the ACM?
Take Pre-Cooled or APU Bleed Air and cool it to as low as 5C
When does Baggage Heat become available?
In flight when selected (WOW)
When will Acoustic Seal inflate?
Assuming Service Air is available when the door is closed and the Left throttle is out of Cutoff
What does a Cyan BAGGAGE HEAT FAIL CAS message indicate?
Baggage Heat Valve is closed when commanded open
What does an Amber BAGGAGE HEAT FAIL CAS message indicate?
Valve Failed open when commanded closed
When will Baggage Heat not come on?
- O’TEMP
- BAGGAGE HEAT FAIL (165F)
- On the ground
- BAGGAGE FIRE
- FIRE BOTTLE LOW
Will the Acoustic Seal remain inflated inflight with the Left Engine shutdown?
Yes
When does Baggage Heat turn OFF automatically?
- WOW
- 100F
- 165F
- Any FIRE CAS message
What happens with an Amber ACM BLEED LEAK CAS message?
EMER Pressure
True or False: An Amber STAB BLEED LEAK CAS message will extinguish when the sensors have cooled
False
