Q.2.1. What are the three sources of Bleed Air?
Engines, APU, or an external air cart/source.
Reference: FRM 2.2.1
Q.2.2. What are some systems that rely on Bleed Air?
- Air conditioning/pressurization
- Wing and engine thermal anti-icing
- Engine starting
- Hydraulic reservoirs pressurization
- Water tank pressurization
- Nitrogen generation system
- Aspirated TAT probe
Reference: FRM 2.2.1
Q.2.3. On the NG, what does a BLEED TRIP OFF light mean, what happens, and can it be reset?
- Illuminates when engine bleed air temperature or pressure exceed a predetermined limit.
- The engine bleed valve closes automatically.
- If temperature and/or pressure have returned to a normal range, it can be reset with the TRIP RESET button.
Reference: FRM B737NG 2.1.1, 2.2.2.2
Q.2.4. What is the purpose of the WING-BODY OVERHEAT light?
Indicates overheat from bleed air duct leak.
Reference: FRM 2.1.1, FRM B737NG 2.2.2.9, FRM B737MAX 2.2.2.11
Q.2.5. Where does the Wing-Body Overheat system monitor for both the Left and Right side?
- Left/Right engine strut
- Left/Right inboard wing leading edge
- Left/Right-hand air conditioning bay
Reference: FRM 2.1.1, FRM B737NG 2.2.2.9, FRM B737 MAX 2.2.2.11
Q.2.6. What two unique areas does the Left side Wing-Body Overheat system monitor?
- Keel beam
- Bleed duct from APU
Reference: FRM 2.1.1, FRM B737NG 2.2.2.9, FRM B737MAX 2.2.2.11
Q.2.7. What is the purpose of the TRIP RESET switch?
- 700: Resets BLEED TRIP OFF, PACK TRIP OFF, and DUCT OVERHEAT lights
- 800: Resets BLEED TRIP OFF, PACK, and ZONE TEMP lights
- MAX: Resets BLEED, PACK, or ZONE TEMP lights
Reference: FRM B737 -700/-800 2.1.1, 2.1.2, FRM MAX 2.1.2
Q.2.8. With the Isolation Valve switch in AUTO, when will the valve automatically go from closed to open?
Opens automatically if either engine BLEED air or air conditioning PACK switch is positioned OFF.
Reference: FRM 2.1.1, 2.1.2
Q.2.9. In the -700, what would cause the PACK TRIP OFF light to illuminate? What happens?
Indicates pack temperature has exceeded limits. Related pack valve automatically closes and mix valves drive full cold.
Reference: FRM B737NG 2.1.2
Q.2.10. In the -800, what would cause a PACK light to illuminate? What about on recall?
- Pack trip off (over temperature) or
- Failure of both primary and standby pack controls or
- Failed closed Smart Ram Air Door Actuators (SRADA) system fault (as installed)
Recall
- Failure of either primary or standby pack control or
- Smart Ram Air Door Actuator (SRADA) system fault (as installed)
Reference: FRM B737NG 2.1.2, 2.4.7
Q.2.11. If an amber caution light illuminates only on MASTER CAUTION recall but goes out when the MASTER CAUTION is reset, is running the associated QRH required?
No.
Reference: AOM 5.1.1.2
Q.2.12. In the MAX, what would cause both PACK lights to illuminate?
Incorrect pack configuration after takeoff or go-around 45 seconds after flap retraction.
Reference: FRM B737MAX 2.1.2, 2.3, MAX QRH 2.22
Q.2.13. What does a DUAL BLEED light mean?
APU bleed air valve open and engine No. 1 BLEED air switch ON, or engine No. 2 BLEED air switch ON, APU bleed air valve and isolation valve open.
Reference: FRM 2.1.1, FRM B737NG 2.2.2.7, FRM B737MAX 2.2.2.9, B737NG QRH 2.12, B737MAX QRH 2.17
Q.2.14. In the -700, what would cause the DUCT OVERHEAT lights to illuminate and what happens?
Distribution air temperature in related duct exceeds limit. Air mix valves drive full cold.
Reference: FRM B737NG 2.1
Q.2.15. In the -800, what would cause the ZONE TEMP lights to illuminate? During recall?
Illuminates
- CONT CAB indicates a duct temperature overheat or failure of the flight deck primary and standby temperature control.
- FWD CAB or AFT CAB indicates duct temperature overheat.
Illuminates during recall
- CONT CAB - indicates failure of the flight deck primary or standby temperature controller.
- Either FWD CAB or AFT CAB indicates failure of the associated zone temperature control.
Reference: FRM B737NG 2.1.2, 2.4.9
Q.2.16. In the MAX, what causes the ZONE TEMP light(s) to illuminate?
CONT CAB indicates a duct temperature overheat or failure of the flight deck primary and standby temperature control.
FWD CAB or AFT CAB indicates duct temperature overheat.
