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’
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’ 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
Manual pressurization knob (normal position), 2/3rds position FPM, Full deflection FPM
12 o’clock position Rate is zero
2/3’s travel is about 1000 fpm
Full deflection is about 2500fpm
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 <500 from for >10s
Aircraft is climbing at any rate with aircraft altitude greater than 25000’
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.
GEAR WARNING
Non-mutable
Any gear not down/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 (5)
Active when:
Left hydraulic system pressurized Nose Gear down and locked WOW NWS selected ON No faults noted by SCU (steering control unit)
PSEU
Proximity Sensing Electronic Unit
=Gear retraction and extension control
Gust lock - What does it protect
Locks ailerons only
These are the only non-hydraulic flight control
MDC
Maintenance Diagnostic Computer
Can display data on top half of right MFD BY PRESSING A/ICE, ECS, and FUEL on the MFD Control Panes
