Front 1

PRIMARY & SECONDARY FLIGHT CONTROLS ARE

Back 1

PRIMARY-AILERONS, ELEVATOR,
SECONDARY-SPOILERS, HIGH LIFT DEVICES

Front 2

FLT SPOILERS AND GND SPOILERS CONTROL

Back 2

FLIGHT-ROLL CONTROL & TO SLOW THE A/C
GROUND-SLOW THE A/C

Front 3

HIGH LIFT DEVICES DO WHAT

Back 3

INCREASE WING AREA AND CHANGE THE SHAPE OF THE WING TO INCREASE LIFT AT LOW SPEEDS
IE-4 LE SLATS,2 LE FLAPS,INBD AND OUTBD DOUBLE SLOTTED FLAPS

Front 4

FLAP SETTINGS 1-15 EFFECT IS
FLAPS MORE THAN 15 EFFECT

Back 4

1-15 INCREASE LIFT WITH A SMALL CHANGE IN DRAG
MORE THAN 15-INCREASE LIFT AND DRAG TO PERMIT SLOWER SPEEDS AND BETTER CONTROL

Front 5

CNTL WHEELS ARE CONNECTED TO EACH OTHER AND TO

Back 5

THE AILERON POWER CNTL UNIT(PCU)

Front 6

SPOILER SWITCHES ARE FOR

Back 6

MAINTENANCE PERSONNEL FOR SYST TESTS

Front 7

HOW DO FLT SPOILERS WORK

Back 7

HELP TURN A/C
HYDRAULICALLY OPERATED AND START TO MOVE WHEN CNTL WHEEL MOVES MORE THAN 10 Deg

Front 8

JAMMED AILERON

Back 8

THE TRANSFER MECHANISM ALLOWS YOU TO ROLL THE A/C. APPLY FORCE TO THE F/O CNTL WHEEL OPERATES THE SPOILERS TO ROLL THE A/C CAPT WHEEL DOESN'T MOVE

Front 9

SPOILER JAM

Back 9

FORCE APPLIED TO THE CAPT WHEEL OPERATES THE AILERON TO ROLL THE PLANE, F/O CNTL WHEEL DOESN'T MOVE

Front 10

ELEVATORS MOVED BY

Back 10

1-CNTL WHEEL
2-AUTO-PILOT
3-MACH TRIM SYST

Front 11

ELEV PCU HYD PRESS FROM

Back 11

BOTH SYST A & B

Front 12

HOW DOES THE AUTOPILOT MOVE THE ELEVATOR

Back 12

IT SENDS A SIGNAL TO THE ELEV FEEL AND CENTERING UNIT. THIS SIGNAL IS ADDED TO STAB POSITION, HYD PRESS AND PITOT STATIC INPUTS IN THE ELEV FEEL COMPUTER TO TELL THE ELEV HOW MUCH TO MOVE

Front 13

HOW DOES MACH TRIM WORK

Back 13

FOR SWEPT A/C AS SPEED INCREASES TOWARDS MACH 1 THEY START TO PITCH DOWN BECAUSE OF AERODYNAMIC FORCES ON THE A/C
-THE AIR DATA PART OF THE ADIRU SEES AIRSPEED AND SENDS A SIGNAL TO THE FCC'S

Front 14

MACH TRIM IS AUTOMATIC FROM WHAT SPEED

Back 14

AT SPEEDS ABOVE 0.615M

Front 15

HOW IS MOVEMENT OF STAB TRIM IS AFFECTED BY FLAP POSITION

Back 15

FLAPS EXTENDED TRIM MOVES FASTER, FLAPS UP MOVES SLOWER

Front 16

STAB TRIM NOT IN T/O RANGE YOU GET WHAT WARNING

Back 16

AN INTERMITTENT HORN IF THE YOU TRY TO T/O

Front 17

AUTOMATIC SPEED TRIM ADJUSTS TRIM TO

Back 17

IMPROVE MANUAL FLT CHARACTERISTICS

Front 18

CONDITIONS FOR SPEED TRIM OPS

Back 18

1-WHEN A/P DISENGAGED
2-LOW GROSS WT
3-AFT CG
4-HIGH THRUST

Front 19

SPEED TRIM MOST FREQ OPERATES WHEN AND HOW

Back 19

-DURING LOW SPEED, AT HIGH THRUST SUCH AS T/O AND G/A
-OPS BY SENDING A SIGNAL TROUGH THE A/P SYST TO MOVE THE STABILIZER

Front 20

WHEN DOES SPEED TRIM STOP

Back 20

-WHEN YOU ENGAGE THE A/P
AND WHEN YOU USE ELEV TRIM

Front 21

FEEL DIFF PRESS LT ILLUMS WHEN

Back 21

ELEVATOR FEEL COMPUTER SENSES A SIGNIFICANT HYD PRESS DIFF B/WEEN SYST A & B AND THE FLAPS ARE UP
-ALSO A BLOCKED PITOT TUBE CAUSES THIS AS WELL

Front 22

WILL THE FEEL SYST WORK WITH ONLY ONE HYD SYST AND ANY CREW ACTION RQD

Back 22

YES IT WILL WORK
NO CREW ACTION IS REQUIRED

Front 23

SPEED TRIM FAIL LT TELLS YOU WHAT

Back 23

TELLS OF A DUAL CHANNEL SPEED TRIM FAILURE IN THE FLT CNTL COMPUTER

Front 24

SINGLE CHANNEL SPEED TRIM FAILURE SHOWN BY WHAT ANNUNs

Back 24

MAKES THE MC AND FLT CNTL ANNUNs TO ILLUMINATE IF MC RECALL SYST IS ACTIVATED. NO CREW ACTION IS RQD FOR SINGLE OR DUAL FAILURE

Front 25

MACH TRIM FAIL LT SHOWS

Back 25

THIS ILLUMS WITH MC LTS IF THERE IS A DUAL CHANNEL MACH SYST FAILURE

Front 26

SINGLE CHANNEL MACH TRIM FAILURE

Back 26

MAKES MC LT AND FLT CNTL ANNUN COME ON WHEN THE RECALL SYSTEM IS ACTIVATED. NO CREW ACTION RQD

Front 27

STAB OUT OF TRIM LT

Back 27

THIS ILLUMS FOR A MOMENT IF THE A/P REQUIRES A LARGE TRIM CHANGE AND THE STAB IS NOT IN THE CORRECT POSITION

Front 28

STAB OUT OF TRIM FOR A LONG PERIOD MEANS

Back 28

A MALFUNCTION HAS OCCURRED. REQUIRES YOU TO HOLD THE CNTL WHEEL, DISCONNECT THE AUTOPILOT AND TRIM THE STABILIZER

Front 29

CUT OUT SWITCH WORKS HOW

Back 29

IF CNTL COLUMN IS MOVED OPP TO TRIM SYST OR CNTL COLUMN IS IS MOVED OUT OF THE USUAL RANGE A CUT OUT SWITCH STOPS ALL STAB TRIM OPERATION

Front 30

WHEN DOES THE STAB TRIM SWITCH OVERRIDE WORK

Back 30

WHEN STAB TRIM IS STOPPED OUT OF RANGE MOVE THE STAB TRIM SW TO OVERRIDE PERMITTING STAB TRIM OPS

Front 31

THE YAW CONTROL INPUTS ARE

Back 31

MANUAL-RUDD PEDALS AND RUDDER TRIM
AUTOMATIC-THE YAW DAMPER, STANDBY YAW DAMPER DURING MANUAL REVERSION FLIGHT
