4
Q
A
- possible metal contamination in the forward gear reduction case oil supply
5
Q
A

11
Q
A
- indicates that the designated generator is off-line
12
Q
A
- indicates that the designated bus is isolated from the Center bus
13
Q

17
Q
A
motive flow pressure lost while fuel remains in the Aux tank on the designated side
18
Q
A
- the designated side has less than 30 mins fuel remaining at max continuous power
19
Q
A
- the crossfeed valve is in the selected position
20
Q
A

21
Q
A
- the designated landing gear is down-and-locked. If any of the lights do not illuminate after gear extension or the gear handle light remains illuminated, gear may be unsafe.
22
Q
A
- landing gear in transit
- one or more gear(s) not down and locked
- one or more gear(s) not fully retracted
- landing gear UP and on or both power levers retarded below approximately 84% to 86% N1

23
Q
A
the landing and/or taxi light are on with landing gear up
24
Q
A
Rudder Boost switch is off
25
Airstair or cargo door is unlocked or open
26
cabin pressure altitude exceeds 12,000 ft
27
cabin differential pressure exceeds 6.9 PSI
28
Melted or failed plastic bleed air failure warning line. Monitor during engine start. Either engine extinguishes both annunciators upon starting.
These annunciators may also illuminate momentarily during simultaneous wing boot and brake deice operation at low N1.
If annunciator immediately goes away, disregard.
29
Oxygen arming handle is not pulled or the system failed to charge.
30
The designated bleed air switch is not in OPEN position.
31
Floor distribution air duct temperature has reached 300°F.
32
Indicates that the electric heat power relay is closed and applying power to the electric heat power control relay for the heating elements.
May also illuminate during simultaneous wing boot and brake deice operation at low N1 speeds.
33
The passenger oxygen system is charged and available to passenger masks.
34
Cabin altitude exceeds 10,000 ft.
35
* Right engine N1 is too low for air conditioning load. (Below 62% N1)
* Air conditioning clutch has disengaged.
36
The designated anti-ice vane system is inoperative.
37
the pitot mast heat is inoperative.
the annunciator will also illuminate anytime the PITOT switch is in the OFF position.
38
Designated engine anti-ice vanes are in position for icing conditions.
39
Wing surface deice system is operating.
40
Horizontal stabilizer surface deice system is operating.
41
Designated brake deice system is operating.
