RECIRC INOP
recirc fan is failed or not operating
recirc fan sw OFF
PACK INOP lgt
pack is overheated
fault in the auto control system
PACK RESET
resets an overheated pack if the pack has cooled to a temp below the overheat level
foot and shoulder heaters
an electric heater adds heat at HIGH or LOW setting to the conditioned air flowing to the area
Equip cooling sel
STBY - positions equip cooling sys for inboard air flow
OVRD - positions equip cooling sys for reverse air flow, shuts down NGS if installed

AUTO INOP lgt illuminates
DUCT LEAK lgt
high temp bleed air leak is detected in the C pneumatic duct
system test
Engine bleed air OFF lgt
engine bleed air valve is closed:
auto due to sys fault
the sw is OFF
the engine is not running
DUCT LEAK lgt
a high temp bleed air leak is detected in left, right or engine strut pneumatic duct
BLEED lgt
engine high pressure bleed air valve and/or pressure regulating valves are open when they should be closed
OVHT lgt
engine bleed air overtemp
engine bleed valves auto closed
PACK non-normal ops
pack control, fault detection, and overheat protection are all auto
pack INOP lgt and L or R PACK TEMP for all pack control sys faults and overheats
The pack valve closes and the pack is shut down auto when an internal pack overheat is detected. PACK OFF lgt and L or R pack OFF in addition to PACK TEMP.

FLT DECK TEMP, FWD CABIN TEMP, MID CABIN TEMP OR AFT CABIN TEMP
zone supply duct overheat
ZTC failure
trim system is OFF
compartment temp control is off
equip cooling components
a supply fan and an exhaust fan either recirculate the cooling air back through the system, or port it overboard.
in flight, only the exhaust fan operates, and the air recirculated through the system
cargo heat non-normal ops
cargo ht OVHT lgt and EICAS FWD, AFT or BULK CARGO OVHT when temp above std control range.
Shutoff valve closes when 32 deg exceeeded, reopens once temp reduced.
press. schedule in cruise
after level-off the landing alt and scheduled cabin alt are compared and the higher is selected for cruise cabin alt.
Cabin climbs to cruise alt at half-rate of the auto rate or descends at the auto rate.
bleed air OVHT valve position
If a bleed air overheat occurs, the engine bleed air valve is auto closed. With the engine bleed air valve closed, the HPSOV and PRV are closed. Activation of engine anti0ice will cause the PRV to open to provide cowl anti-ice unless a strut duct leak exists.
ICING lgt
ice detect sys indicates ice buildup on the airplane
Window ht INOP lgt
the window is not being heated
Wiper INT
every 7 secs
WAI how many slats
three outboard slats
pressing engine anti ice
engine anti-ice valves open, allow engine bleed air to anti-ice the engine cowl inlets.
pressing WAI
in flight, commands wing anti-ice valve in each wing to open, allowing bleed air to flow from the bleed air manifold to the affected slats.
