Q

EMER DEPRESS switch

A

Depressurizes cabin at rate of 2500 fpm up to 14000’ +/- 100’ or aircraft altitude which ever is lower.

In manual mode, cabin depressurizes at rate of 3000 fpm up to 14,000’ or aircraft altitude +/- 500 which ever is lower

Q

TAKEOFF AND RETURN TO BASE mode

Automatic pressurization modes

A

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

–Maintains this altitude until 6000’ 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’ may cause cabin rate of climb to exceed 635 fpm max and should be avoided for cabin comfort.

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.

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.
OFV THEN REMAINS FULLY OPEN WHILE ON GROUND.

NWS LIMIT EXCEEDED CAS msg tripped when steering angle exceeded

*Unlimited steering available with torque link disconnected and nose wheel strut has at least 3.5” of chrome extended

20
Q

EQUIPMENT Doors that must be UNLOCKED FOR FLIGHT

A

Battery Bay

Outflow Valve Door

21
Q

Gust lock

A

Locks ailerons only

These are only non-hydraulic flight control

22
Q

A

CVR starts recording when power is applied

Records 120 min

Can be erased on ground with park brake set and hydraulic power on

23
Q

FDR

A

Comes on with beacon light selected on or WOW

RECORDS 25 hours of data

24
Q

MDC- maintenance diagnostic computer

A

Can display data on top half of right MFD BY PRESSING A/ICE, ECS, and FUEL on the MFD Control Panes

25
Q

4.2 to one bypass ratio turbofan

FADEC controlled

27
Q

APR ARMED

A

Armed for takeoff when thrust levers at T/O detent or above.

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

28
Q

AIR TURBINE STARTER Disengage

29
Q

When do the HYD SHUTOFF VLV’s close

Fire switch depressed

Shut off valve closed

Fluid temp above 135°C (skydrol boiling point)

30
Q

What is the power source for the HYD DCMP’s

A

Left DMCP……….RIGHT MAIN BUS

Right DCMP……..LEFT ESSENTIAL BUS

31
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.

32
Q

What does the AUX HYD system power?

A

33
Q

How are gear up locks released?

A

When extension commanded, gear initial over stows the gear, releasing the mechanical up locks. This allows mechanical up lock hook to be retracted for extension.

A

Pressing either master disconnect switch

Activating trim switches on control wheels

Pressing AP on FGP

Pressing AP/DISC bar on FGP

Pressing either TOGA switch on TL’s

Pressing the YD push button
