EMER DEPRESS switch
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
Ditching switch (pressurization panel)
Pressing switch:
Depressurizes the cabin
Shuts off air conditioning
Keeps OFV closed
*This sequence is only active in the automatic mode and is inhibited above 15000’
CABIN ALTITUDE
CAS message
Caution at 8500’
Warning at 9400’
Airports above 7850’ MSL resets msgs to:
Caution 9,100
Warning 10,900
IASC
Integrated Air System Controllers
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’ 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.
PRE PRESSURIZATION MODE
Automatic pressurization modes
Active from time thrust levers go to take off position
Achieve cabin pressure of 300’ below take off elevation
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’ 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
Cabin altitude is set according to predetermined schedule.
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.
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 GROUND.
GEAR WARNING-NON mutable
Any gear not down and locked and
RADALT < 500’ and
Left and right thrust levers < 26° Or flaps > or = 27°
GEAR WARNING - mutable
When RADALT INOP Gear Warning is mutable.
Gear not down and locked and
TLA < 26° and
Altitude is <15,000’ and one of the following :
Airspeed <170 with flaps <3°, Airspeed <160 with flaps <13°’ Airspeed <155 with flaps >13°
Brake system ground mode
Ground mode allows hydraulic pressure to brake actuators.
Activated when gear down and either WOW active for >5 sec or wheel spin up above 50 KTS
Brake Control Unit - BCU
Provides anti-skid protection down to 10 KTS
Commands braking pressure of 350 psi for 4 seconds after gear retraction
Removes hydraulic pressure from brakes when:
Both WOW(off), and gear up and locked, and wheel speed zero.
Nose Wheel Steering
Active when:
Left hydraulic pressure system pressurized
Nose Gear down and locked
WOW
NWS selected on
No faults noted by SCU (steering control unit)
PSEU
Proximity Sensing Electronic Unit
