4

How many heated pitot probes are on this B-737NG?

5

The 737 has ________ pitot probes

5

Bleed air comes from the _____ and ______ compressor stages?

5th and 9th

The 737 has ________ static ports

6

The cabin of a B737 can be pressurized up to a cabin altitude of ____________.

8000ft

What does the pressurization system use to control pressurization and ventilation?

An outflow and overboard exhaust valve

Differences between the L and R duct pressure indicators

Are considered normal, as long as the cabin can be pressurized

The wing anti ice switch will move to the OFF position without crew action when:

At lift off when the air ground sensor goes to the air mode

In ALTN mode which of the following is true:

Automatic pressurization control; the alternate mode of operation; uses a DC motor

The APU bleed air valve closes

Automatically when the APU is shut down or when the pilot selects the APU bleed air switch to off

Anti Ice valves are ___________ in transit and _________ when OPEN.

Bright blue and dim blue

Which of the following WILL NOT cause a takeoff warning?

Cockpit door not locked.

Engine bleed air valves are

DC activated and pressure operated

On the ground and at low power settings the cabin is depressurized by

Driving the outflow valve to the full open position

In normal operation the right pack uses bleed air from

Engine n2

Alerts from the GPWS system are based on

Estimated time to impact

An amber COWL ANTI-ICE light illuminates due to:

Excessive pressure

A single pack in high flow can maintain temperatures and pressurization up to

FL410

All flight deck windows are heated.

False

If a flight has to return to the airport immediately after takeoff the MAN light will illuminate indicating that the aircraft failed to reach the preset cruising altitude

False

If acted on immediately, a ground proximity alert guarantees terrain clearance

False

In flight the overboard exhaust valve is the exit for the majority of the air and the outflow valve is normally closed.

False

Windshear alerts are available during cruise

False

Which of the following is not a function of the bleed air system?

Fuel tank pressurization

In MAN mode which of the following is true:

Manual control of the system using a DC motor

The vertical stab and horizontal stab have anti ice from:

Not APU, or Right or the Left Engine

The cabin begins pressurizing

On the ground at high power settings

The overboard exhaust valve is open to allow warm air from the E & E compartment to be discharged overboard, in what conditions?

On the ground or in flight with low differential pressure

Mode Control of the TCAS is set to TA/RA; however, can be set to TA ONLY when:

Parallel Approach AND Busy airports AND Near other airplane such as VFR conditions

Rain removal for the forward windows, R1 and L1 consist of wipers and:

Permanent rain repellent

In the air conditioning system what cools the bleed air in the heat exchangers?

Ram air

Indications that require immediate crew attention are

Red

Voice warnings are not used for

Stall warnings

During slow flight with the flaps partially extended the ram air doors move to the full open position and

The RAM AIR DOOR FULL OPEN light will illuminate

The DUAL BLEED light will illuminate when

The bleed air system is configured such that it would be possible to put backpressure on the APU

If an overheat is detected in the cooling cycle which of the following will occur

The pack valve will close AND The PACK TRIP OFF light will illuminate

If during cruise flight, both air conditioning pack switches are in AUTO and one pack fails what will occur?

The remaining pack will switch to high air flow

TCAS uses ___________ of possible conflicting traffic.

Transponders

A small amount of air is exhausted through toilet and galley vents, and miscellaneous fixed vents and seal leakage.

True

An external air cart can supply air for engine start or air conditioning

True

Bleed air can be supplied to the aircraft via the APU, an external air cart or the engines.

True

Continuous ignition is required by most airlines policy prior to engine or wing anti ice activation.

True

Each pitot air data module is connected to its on-side pitot probe

True

It is possible to operate two packs from one engine bleed air source but the manual states it should not be done.

True

Static ports are not heated.

True

The Head-Up Display (HUD) can be used with the autopilot or when the aircraft is being hand flown

True

The left and right wings are NOT heated, inboard of engines.

True

The pilots can turn on the recirculation fans directly.

True

The recirculation fan reduces the load on the packs and bleed air demand.

True

Primary engine indications are on the _______ DU

Upper

The Mach/Airspeed warning clacker will sound any time

Vmo/Mmo is exceeded

The isolation valve

Will be closed during normal operations (both packs operating, both engine bleeds on)

The bleed air valves protect the system

by automatically closing when an over pressure or over temperature is detected
