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

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 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

Canberra manually turned off on engine panel

21
Q

AIR TURBINE STARTER Disengage

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

27
Q

The GEN overload message comes on at what load?

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 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 gear and flaps are extended to smooth out oscillations

32
Q

Min Speed to extend FLIGHT SPOILERS

A

Vapp + 8

Vapp=Vref straight in approach. (+8)

Vapp=Vref+10 circling approach (+8)

500’ AGL min usage

33
Q

38
Q

RA INHIBIT

A

Below 900’ AGL, descending
Below 1100’ AGL climbing …………All RA’s inhibited (TA ONLY) and TA AURAL INHIBITED

Below 1000’ AGL descending
Below 1200’ AGL, climbing ……..DESCEND RA inhibited

Below 1450’ AGL …………INCREASE DESCENT inhibited

39
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

If in AUTO mode, when will the DCMPs run constant?

What is the pressure the provide?

A

Flaps out of 0

2800 PSI

45
