Ditching switch (pressurization panel) (3)
Depressurizes the cabin
Shuts off air conditioning
Closes Outflow valve.
*This sequence is only active in the automatic mode and is inhibited above 15000 ft
IASC
Integrated Air System Controllers = Pressurization control
Two controllers, #1 is always primary #2 takes control automatically when #1 has a fault Controls primary outflow valve through AUTO drive mechanism
(Secondary independent drive mechanism control valve in manual mode)
TAKEOFF AND RETURN TO BASE mode *Automatic pressurization modes*
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.
PRE PRESSURIZATION MODE
*Automatic pressurization modes*
Active from time thrust levers go to take off position
Achieve cabin pressure of 300 ft below take off elevation
Manual pressurization knob
12 o’clock position Rate is zero
2/3’s travel is about 1000 fpm
Full deflection is about 2500 fpm
CLIMB mode
*Automatic pressurization modes*
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.
CRUISE MODE
*Automatic pressurization modes*
Active when Aircraft rate of climb < 500 from for > 10s
Aircraft is climbing at any rate with aircraft altitude greater than 25000 ft
Cabin altitude is set according to predetermined schedule.
Depressurization sequence on ground *Automatic pressurization modes*
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 the ground.

or
Wheel spin up above 50 KTS

Removes hydraulic pressure from brakes when:
Both WOW (off)
Gear Up and Locked
Wheel Speed Zero
Nose Wheel Steering
(5)

APR ARMED
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
AIR TURBINE STARTER
Disengage
N2 46.2%
When do the HYD SHUTOFF VLV’s close
Fire switch depressed
Shut off valve closed
Fluid temp above 135°C (skydrol boiling point)
What is the power source for the
HYD DCMP’s
Left DMCP: RIGHT MAIN BUS
Right DCMP: LEFT ESSENTIAL BUS
What is the primary purpose of the PTU
When does it run
To aid in gear retraction
Comes on when gear is being retracted and left EDP pressure is low
What does the AUX HYD system power
Assists the lower rudder PCU
How are gear up locks released
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.
The GEN overload message comes on at what load?
501 AMPS
What inputs arm the GROUND SPOILERS in AUTO mode
(4)
Inputs come from :
RADALT
Wheel Speed
WOW
TLA
When do GROUND SPOILERS extend in MANUAL ARM
Thrust Levers Idle and WOW (on) only
*Manual Arm mode does not provide additional input protection available in AUTO.
ALTN FLAPS
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
CONFIGURATION TRIM
Stab trim automatically adjusts when:
Flaps are extended/retracted
Spoiers are extended or retracted
*Reduces control column forces
How long may windshield heat be used when on essential power?

TCAS RA INHIBIT
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
DESCENT MODE
*Automatic pressurization modes*
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
