Q

TAKEOFF AND RETURN TO BASE mode *Automatic pressurization modes*

A

System maintains take off pressurization of 300 ft below take off field elevation

Maintains this altitude until 6000 ft or 10 minutes

*If descent is initiated the cabin descends to take off field elevation and the cabin altitude does not have to be reset.

Q

CLIMB mode

*Automatic pressurization modes*

A

Automatically controls cabin climb rate according to theoretical schedule of aircraft altitude and cabin altitude taking into account aircraft rate of climb and landing field elevation.

Typical climb rates are 300-500 fpm with max rate of 635 fpm

*High rates of climb above 6000 fpm above 25,000 ft may cause cabin rate of climb to exceed 635 fpm max and should be avoided for cabin comfort.

Q

Depressurization sequence on ground *Automatic pressurization modes*

A

After landing or aborted takeoff aircraft depressurizes at rate of 500 fpm, then outflow valve drive to fully open.

Q

APR ARMED

A

Armed for takeoff when Thrust Levers at T/O detent

Engaged when Thrust Lever set at APR (beyond takeoff position)

Also armed for go around when flaps > 20° or flaps and gear down

Automatically engages with engine split of > 15% N2

Can be manually turned off on engine panel

21
Q

AIR TURBINE STARTER

Disengage

A

N2 46.2%

22
Q

When do the HYD SHUTOFF VLV’s close

A

Fire switch depressed

Shut off valve closed

Fluid temp above 135°C (skydrol boiling point)

23
Q

What is the power source for the

HYD DCMP’s

A

Left DMCP: RIGHT MAIN BUS

Right DCMP: LEFT ESSENTIAL BUS

24
Q

What is the primary purpose of the PTU

When does it run

A

To aid in gear retraction

Comes on when gear is being retracted and left EDP pressure is low

25
Q

What does the AUX HYD system power

A

Assists the lower rudder PCU

26
Q

How are gear up locks released

A

When extension commanded, hydraulic pressure initially over stows the gear, releasing the mechanical up locks.

This allows mechanical up lock hooks to be retracted for extension.

27
Q

The GEN overload message comes on at what load?

A

501 AMPS

28
Q

What inputs arm the GROUND SPOILERS in AUTO mode

(4)

A

Inputs come from :

RADALT

Wheel Speed

WOW

TLA

29
Q

When do GROUND SPOILERS extend in MANUAL ARM

A

Thrust Levers Idle and WOW (on) only

*Manual Arm mode does not provide additional input protection available in AUTO.

30
Q

ALTN FLAPS

A

When selected, left HYD system pressure powers flaps

Flow restricted (to prioritize gear actuation)

Takes over 1 min to extend flaps from 0°-20°

*Normal flaps (right HYD system) O°-30° is 20 seconds

31
Q

CONFIGURATION TRIM

A

Stab trim automatically adjusts when:

Flaps are extended/retracted

Spoiers are extended or retracted

*Reduces control column forces

32
Q

How long may windshield heat be used when on essential power?

A

15 minutes

33
Q

37
Q

TCAS RA INHIBIT

A

Below 900 ft AGL descending Or Below 1100 ft AGL climbing: All RA’s inhibited (TA ONLY) and TA AURAL INHIBITED

Below 1000 ft AGL descending Or Below 1200 ft AGL climbing: “DESCEND RA” inhibited

Below 1450 ft AGL: “INCREASE DESCENT” inhibited

38
Q

DESCENT MODE

*Automatic pressurization modes*

A

Aircraft descends at preset set rate which varies with aircraft rate of descent and time remaining to land

2000 fpm aircraft rate yields 300 fpm cabin rate

5000 fpm and greater descent rate yields cabin descent of 750 fpm

Decent continues to 300’ below landing field elevation

On center console

43
Q

When will the DCMPs run constant in AUTO mode

At what Pressure

A

Flaps > 0°

2800 PSI

44
Q
