1
ELECTRICAL-While observing the VOLTMETER, to check the voltage on the right generator you should
Assure right generator is ON and select VOLTAGE SEL to RH GEN
Switch the right generator to OFF and select the VOLTAGE SEL to RH GEN
Switch the left generator to OFF and read battery voltage
Switch the left generator to OFF and select the VOLTAGE SEL to RH GEN
2
ELECTRICAL-Which statement is correct, With the battery switch in the OFF position
The emergency exit lights will illuminate
The hot battery bus is powered
The battery bus is powered
The generators will trip off line
3
ELECTRICAL-Which of the following statements are true regarding a generator-assist start.
It is necessary to observe a drop in amperage to below 300 before activating the second start button.
A maximum of 49 % turbine RPM is set on the operating engine.
The operating generators switch must be placed to OFF before the start button is activated.
The operating engine turbine RPM must be stabilized at 49 to 50 % before the remaining start button is activated .
4
ELECTRICAL-The field relay is integral to the GCU (generator control unit).
False
True
5
ELECTRICAL-The left or right generator field relay is opened by
An overvoltage
An internal feeder fault
Activating the engine fire switch
Any of the above
6
ELECTRICAL-With the battery switch selected to EMER a good battery should supply power to the hot battery and emergency for approximately
55 minutes
30 minutes
1 hour
25 minutes
7
ELECTRICAL-If the BATT O'HEAT annunciator illuminates on the ground (except for test), you should
Switch generators to OFF
Select battery switch to EMER and proceed as normal
Not take-off until the proper maintenance procedures have been performed
Disregard if not flashing
8
ELECTRICAL-To assure both start relays have opened after a generator assisted start you should
Check that STARTER DISENGAGE button is not illuminated.
Check that LH START and RH START buttons are not illuminated.
Observe equal loads on ammeters.
Select battery switch to EMER and observe voltage drop to battery voltage.
9
FIRE PROTECTION-The ENG FIRE switchlight illuminates when
An engine fire or overheat condition exists.
The firewall shutoff valve is closed.
The fire extinguisher is discharged.
It is depressed.
10
FIRE PROTECTION-During preflight, the indication that a fire extinguisher bottle has been discharged
Blow out disc missing on the side of the tail cone.
Residue in the engine inlet.
Gauge on the fire bottle.
Annunciator light in the cockpit.
11
FLIGHT CONTROLS-Regarding the elevator trim system
Electric trim has both high and low speed positions.
A runaway electric trim condition can be stopped by pulling the PITCH TRIM circuit breaker.
Trim tab is located on the left elevator only.
The trim tab is controlled only electrically.
12
FLIGHT CONTROLS-With the battery as the only source of power and the battery switch in EMER position
The flaps are operable.
The flaps can be lowered only.
The flap selector handle cannot by moved.
The flaps are inoperable.
13
FUEL SYSTEM-After engine start, the fuel boost pump is deenergized by the
A time delay relay
Start circuit termination.
Discontinuing crossfeed.
Fuel boost pump switch.
14
HYDRAULIC POWER-The Citation hydraulic system is classified as a pressure demand system.
True
False
15
HYDRAULIC POWER-While the hydraulic system is not under pressure, the hydraulic reservoir is pressurized to
By engine bleed air.
4-6 PSI by an internal spring.
Nonel of the answers are correct.
2.7-4 PSI by an internal spring.
16
ICE and RAIN-Switching on both engine anti-ice systems in flight will increase the reading on each ammeter by
5 amps
150 amps
10 amps
20 amps
17
LANDING GEAR-Concerning landing gear auxiliary extension, the correct statement is
After the gear is extended using this procedure, it should be cycled in flight if hydraulic pressure is restored, to release trapped air.
The optimum speed for this procedure is 150 KIAS.
If three green lights are observed after yawing the airplane, it is not necessary to use the pneumatic bottle.
The landing gear handle is placed in the down position to position the door shuttle valves.
18
LANDING GEAR-The gear warning horn cannot be silenced when one or more gears are not locked down and
Airspeed is less than 150 KIAS
Either throttle is retarded below 70% turbine RPM.
Both throttles are retarded below 70% turbine RPM.
Flaps are extended beyond 15 degree position
19
MASTER WARNING-With the battery as the only source of power, the annunciators are operative when the battery switch is in the EMER position
False
True
20
POWERPLANT-Ignition during normal engine start is activated by
Moving the throttle to idle at 8 to10 % turbine speed
Automatically when engine turbine speed reaches 10%
Depressing the start button
Turning the ignition switches on at 8 to 10 % turbine speed.
21
POWERPLANT-The minimum oil temp (degrees C) for starting is
10
-40
0
-50
22
PRESSURIZATION-If the main vacuum source to the pressurization controller is lost, the cabin pressure differential will
Be controlled by the altitude limit valves.
Go to maximum differential allowed by the outflow valves.
cause the oxygen mask to drop (if armed).
Decrease to zero
23
PRESSURIZATION-The tail cone is pressurized by ram air to
Provide air flow to the aircycle machine.
Preclude entry of any external fluids
To provide pressure to the hydraulic reservoir.
To provide emergency pressurization if needed.
24
LIMITATIONS-The maximum tire groundspeed is
200 MPH
150 Knots
165 MPH
165 Knots
25
LIMITATIONS-The maximum allowable water/slush on runway for take-off and landing is
0.5 inch
0.4 inch
