Q

For aircraft that do not have the MASK/BOOM switch on the ACP, how do you activate/deactivate the mask microphone?

A

To activate, pull the mask out of the stowage compartment which opens the left door and activates the mask microphone. To get boom microphone back, close the left door and push RESET/TEST switch or TEST/RESET switch

Q

What is the purpose of the TRIP RESET switch?

A

-700: resets the BLEED TRIP OFF, PACK TRIP OFF, and DUCT OVERHEAT lights
-800: resets BLEEDD TRIP OFF, PACK, and ZONE TEMP lights
MAX: resets BLEED, PACK or ZONE TEMP lights

16
Q

-800, what would cause a PACK light to illuminate? On recall?

A

Illuminated amber:
-indicates a pack trip off or failure of both primary and standby pack controls
OR
-indicates a failed closed SRADA system fault on the -800 as installed

During master caution recall:
-indicates failure of either primary or standyby pack control
OR
-indicates a SRADA system fault (as installed). Extinguishes when Master Caution is reset

17
Q

If an amber caution light illuminates on MASTER CAUTION recall but then goes out when the MASTER CAUTION is reset, do you need to run the QRH?

A

No.

18
Q

In the MAX, what would cause both PACK lights to illuminate?

A

Incorrect pack configuration after takeoff or go-around 45 seconds after flap retraction.

19
Q

What does a DUAL bleed light mean?

A

A condition exists where the APU bleed air valve could be back pressured. IE. 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

20
Q

in the -700, what would cause the DUCT OVERHEAT lights to illuminate and what happens?

A

Distribution air temperature in related duct exceeds limit.
the air mix valves drive full cold
requires reset

21
Q

-800. What would cause the ZONE TEMP lights to illuminate? During recall?

A

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: failure of flight deck primary OR standby temperature controller
-FWD CAB or AFT CAB: indicates failure of the associated zone temperature control

22
Q

in the MAX, what causes the ZONE TEMP lights to illuminate?

A

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 temp overheat

23
Q

How many fans are in the equipment cooling system?

A

4 total. A normal and alternate fan for both the supply and exhaust system

24
Q

What would cause the equipment cooling OFF light to illuminate?

A

Loss of airflow due to failure of an equipment cooling fan

25
Q

What are the effects of a forward cargo fire warning on the equipment cooling system?

A

-800 (-700 as installed) and MAX, the equipment cooling exhaust fan is shutoff and the equipment cooling exhaust OFF light is inhibited

26
Q

the MAX has an additional light on the equipment cooling panel, EQUIP SMOKE. Why would it illuminate?

A

Smoke is detected in the equipment cooling system. Light extinguishes 30 seconds after smoke is no longer detected.

27
Q

What does the CABIN ALTITUDE WARNING indicate? How to silence?

A

Cabin altitude has exceeded 10,000 feet. It can be silenced by pressing the ALT HORN CUTOUT switch.

28
Q

What is the policy on silencing the aural alert and resetting the MASTER CAUTION system?

A

Silence any aural alert and reset the MASTER CAUTION system as soon as the cause of the alert is recognized.

29
Q

What causes the OFF SCHED DESCENT light to illuminate?

A

It will illuminate if the aircraft begins a descent without having reached the preset cruise altitude in the FLT ALT indicator

30
Q

What will the pressurization controller scheduling do after receiving and OFF SCHED DESCENT light?

A

The controller programs the cabin to land at the takeoff field elevation unless you reset the FLT ALT setting

31
Q

How many pressure relief valves are on the aircraft?

A

2 positive pressure relief valves and 1 negative pressure relief valve

32
Q

Why is there a CAUTION note associated with using the manual pressurization?

A

The manual motor operates at a higher rate than AUTO or ALTN motor.
A small movement of the outflow valve can cause a large change in cabin rate of climb/descent. That can produce large, rapid changes in cabin pressure which could result in passenger or crew injury or discomfort
