EACH THR REV SYSTEM CONSISTS OF

1-L&R TRANSLATING SLEEVE
2-CASCADE VANES 3-BLOCKER DOORS |
|
|
HOW DOES THE THRUST REV OPERATE
|
-AFT MOVEMENT OF THE TRANSLATING SLEEVES CAUSES BLOCKER DOORS TO DEFLECT AIR FWD THRU FIXED CASCADE GUIDE VANES CAUSING REV THRUST

WHEN CAN YOU USE THE THRUST REV SYST
|
WHEN A/C ON THE GND WITH FWD THRUST LEVERS AT IDLE
|
|
|
EACH THR LEVER HAS HOW MANY POSITIONS
|
1-STOWED
2-INTERLOCK STOP 3-DET No1 4-DET No2 MAX REV |
|
|
WHAT DOES THE INITIAL MOVEMENT OF THRUST LEVER DO
|
1-RELEASES THE ELECTRO-MECHANICAL LOCK & UNLOCKS THE TRANSLATING SLEEVE
2-ISOL VALVE OPEN SIF -AIR/GND SENSOR IS ON GND -RAD ALT SHOWS ALT OF LESS THAN 10FT |
|
|
WITH ISOL VALVE OPEN WHAT HAPPENS TO THE CNTL VALVE
|
1-MOVES TO THE DEPLOY POSOTION
2-HYD PRESS MOVES THE TRANSLATING SLEEVES TO THE DEPLOY POSITION 3-AMBER REV INDICATIONS ILLUMS 4-INTERLOCK MECHANISM RESTRICTS FURTHER MOVEMENT OF THE REV THRUST LEVERS UNTIL THE SLEEVES ARE NEAR THE DEPLOY POSITION 5-AS THE SLEEVES APPR THE DEPLOY POSITION THE REV THR LEVERS CAN BE RAISED TO DET No2 |
|
|
HOW DOES AUTO RESTORE WORK
|
THIS SYSTEM COMPARES THE ACTUAL TRANSLATING SLEEVE POSITION AND THE COMMANDED REV LEVER POSITION
|
|
|
IN THE EVENT OF INCOMPLETE STOW OR TRANSLATING SLEEVE IS SENSED OUT OF THE STOWED POSITION
|
THE AUTO RESTORE SYST OPENS THE ISOL VALVE AND DIRECTS HYD PRESS TO STOW THE REVERSER
-IF THE AUTO RESTORE SYSTEM IS ACTIVATED THE ISOL VALVE REMAINS OPEN AND THE CNTL VALVE IS HELD IN THE STOW POSITION UNTIL CORRECTIVE MAINT ACTION IS TAKEN OR -THE REV THR IS DEPLOYED NORMALLY |

|
REV LTS ON WHEN
|
1-ISOL VALVE OR SEL VALVE NOT IN COMMANDED POSITION
2-IF AUTO RESTORE ACTIVATED 3-IF THERE IS A TRANSLATING SLEEVE DISAGREEMENT |
|
|
POSSIBLE IN FLT DEPLOYMENT WHEN
|
1-REV LT ILLUM ADDITIONAL FAILURES CAN CAUSE INFLT DEPLOYMENT
2-YOU CAN EXPECT NML OPS ON THE GND AFTER LDG |
|
|
REV INDICATION IN FLT COULD BE DUE TO-
|
1-INCORRECT INDICATION OR
2-TRANSLATING SLEEVE HAS MECHANICALLY UNLOCKED -THE FWD THR LEVER MAY BE RESTRICTED AND THE UNSTOWED SLEEVE CAN PRODUCE SOME YAW OR BUFFET |
|
|
ACTIONS OF REV LT IN FLT
|
-AFFECTED ENG-SHUT DOWN
-IF FWD THR LEVER NOT RESTRICTED & NO YAW OR BUFFET THE REV IND IS INCORRECT & THE AFFECTED ENG CAN BE OPRT'D NORMALLY |
