Annunciator Panel

Question 1

Answer 1

Battery over temp
Temp greater than 160
Possible overcharge

Answer 2

Cabin Altitude above 10,000 ft with pressurization controller in the normal mode

Question 3

Answer 3

Low Oil Pressure Warning

Oil pressure below 25 psi

Question 4

Answer 4

Fault has been detected in the respective fuel gauging system. Monitor respective fuel gauge for proper indication. Check fuel quantity after landing.

Gauge unreliable

Question 5

Answer 5

Respective fuel boost pump was either automatically or manually turned on (power was applied)

Question 6

Answer 6

Remaining fuel in the respective tank is 185 +/- 15 LBS, or less

Question 7

Answer 7

Low fuel pressure on the respective engine

Low pressure switch is closed

Low pressure switch closes at 4.65 psi (normal is 6-8 psi)

Question 8

Answer 8

Indicates fuel filter bypass or impending bypass

Filter is clogged and fuel is bypassing the filter

Question 9

Answer 9

Normal operation of the fuel transfer system. The supply tank FUEL BOOST ON annunciator will also be illuminated during normal operations

Question 10

Answer 10

Attenuator switch is in the stow position

Question 11

Answer 11

Generator INOP on respective engine

Power relay is open

Question 12

Answer 12

Indicates an open start control circuit breaker in the aft junction box

Question 13

Answer 13

Indicates an open 225 amp current limiter in the aft junction box.
Normal generated power is available to the respective busses, but the Cross tie buss will not supply power to the respective bus from the battery or from the opposite generator In the event of a generator failure.

Question 14

Answer 14

Applicable ENGINE FIRE switch has been activated. All electrical, fuel, and hydraulic are systems are closed at the applicable firewall

Question 15

Answer 15

Indicates the emergency pressurization system has been turned on at the AIR SOURCE SELECT knob

Air supplied from windshield anti ice system

Question 16

Answer 16

Indicates the AIR SOURCE SELECT knob is set to the FRESH AIR position. The airplane will not pressurize in fresh air mode

Question 17

Answer 17

Indicates INOP pumps

Hydraulic flow rate below normal

With LR or RH lights, probably hydraulic leak

Question 18

Answer 18

Hydraulic system is pressurized because loading valve is closed.

Illuminates normally when the speed brakes, landing gear, or flaps are in the transit or the thrust attenuators are being stowed.

Question 19

Answer 19

Speed brakes are in the fully extended position

Question 20

Answer 20

Respective thrust attenuator is not in the stowed position.

Question 21

Answer 21

Flaps greater than 35 and MASTER CAUTION annunciators will illuminate if the flaps are extended beyond 35 degrees and both throttles are advanced above 85% N2

Question 22

Answer 22

PRW BRK LOW PRESS illuminates if pump pressure switch detects less that 750 psi. It will also illuminate the ANTISKID INOP annunciator

When the gear handle is placed down and the hydraulic brake system pressure is too low

Question 23

Answer 23

Failure or improper position of one or more door switches and or possible disengagement of the lower forward cabin door pin

Question 24

Answer 24

Indicates cabin door primary seal pressure is too low to maintain door seal integrity. Secondary seal should maintain pressurization

Door seal psi less than 8.45

Question 25

Answer 25

Normal operation is indicated by illumination cycles of 6 seconds LH, 6 seconds off, 6 seconds RH, then off, repeating approximately every 3 minutes.

Question 26

Answer 26

If switch is HIGH or LOW, over temp in the system. So select low, reduce windshield bleed valves to minimum flow Air temp to windshield is above 300 degrees

Question 27

Answer 27

AOA heater failure No electrical power to the AOA vane

Question 28

Answer 28

Pitot static heater failure No electric power to the pitot tube heater, or one or both static port heaters

Question 29

Answer 29

Engine inlet temp is below safe level for satisfactory ice protection Under speed or under temp. Illuminates steady after 1 minute after condition was sensed Illuminates flashes and MASTER CAUTION after 2 minutes Increase power above 70%

Question 30

Answer 30

Under speed or under temp Indicates wing leading edge temp is below safe level for satisfactory ice protection. This is normal when wing anti ice is first actuated, until normal temp is achieved, and if engine speed is reduced below approximately 70% N2. Can also indicate wing over temperature.

Question 31

Answer 31

Temp greater than 540 Indicates that malfunction has caused the bleed air leaving the repetitive precooler to exceed allowable temperature. Likely occurs when engine, wind, and or windshield anti ice is on and engine power is high.

Question 32

Answer 32

Cabin supply greater than 300 degrees F Master caution associated Environmental system air duct overheat Select cooler temp, manual mode, then manually select cold.

Question 33

Answer 33

Indicates failure of the visual annunciator test.

Question 34

Answer 34

Indicates failure of the audio annunciator test
