Auto flight part 3

  1. 1. MENU PRINCIPAL
  2. 2. THIS IS PART THREE OF THE AUTOFLIGHT SYSTEM. THE AUTOPILOT ENGAGE SWITCHESARE SPRING LOADED TO, AND MECHANICALLY LOCKED, IN THE DISENGAGED POSITION. ASERIES OF ELECTRONIC INTERLOCKS MUST BE SATISFIED TO RELEASE THE MECHANICALLOCK. THE INTERLOCKS ALSO ENERGIZE A SOLENOID, WHICH HOLDS THE SWITCHES INTHE ENGAGED POSITION.MENU PRINCIPAL
  3. 3. INTERLOCKS FOR THE AILERON ENGAGE SWITCH ARE: A VALID SIGNAL FROM THEVERTICAL GYRO, NO FORCE EXERTED ON THE CONTROL WHEEL, A VALID SIGNAL FROMTHE COMPASS SYSTEM, THE B FLIGHT CONTROL SWITCH ON, AND BOTH AC AND DCELECTRICAL POWER AVAILABLE.MENU PRINCIPAL
  4. 4. THE INTERLOCKS FOR THE ELEVATOR ENGAGE SWITCH ARE: A VALID SIGNAL FROM THEVERTICAL GYRO, NO FORCE EXERTED ON THE CONTROL COLUMN, THE SYSTEM B FLIGHTCONTROL SWITCH ON, AND AC AND DC ELECTRICAL POWER AVAILABLE. IF ANY OF THEINTERLOCKS ARE NOT VALID, THE SWITCH WILL NOT RELEASE FROM THE DISENGAGEPOSITION.MENU PRINCIPAL
  5. 5. THE AILERON AND ELEVATOR ENGAGE SWITCHES MAY BE ENGAGED INDEPENDENTLY ORSIMULTANEOUSLY. THERE IS NO ENGAGEMENT PRIORITY. THE SWITCHES ARE SOLENOIDHELD TO THE ENGAGE POSITION AND SPRING LOADED TO THE DISENGAGE POSITION.MENU PRINCIPAL
  6. 6. THE AILERON SWITCH MAY BE ENGAGED WHILE THE AIRPLANE IS IN A BANK, BECAUSE THE ROLLCHANNEL COMPUTER REMAINS IN CONSTANT SYNCHRONIZATION WITH THE AIRPLANE ATTITUDE.AUTOPILOT ROLL LIMIT IS 32 DEGREES. IF THE BANK ANGLE IS LESS THAN 5 DEGREES WHEN THEAILERON SWITCH IS ENGAGED, THE AIRPLANE ROLLS WINGS LEVEL. THIS FEATURE IS CALLEDWINGS LEVELING. WHEN THE BANK ANGLE IS GREATER THAN 5 DEGREES AND LESS THAN 32DEGREES, THE AIRPLANE MAINTAINS THE BANK ANGLE AT TIME OF ENGAGEMENT. THIS IS CALLEDBANK ATTITUDE HOLD. ENGAGING THE AILERON SWITCH WHEN THE AIRPLANE IS BANKED MORETHAN 32 DEGREES, CAUSES THE AUTOPILOT TO DECREASE BANK TO 32 DEGREES AND MAINTAINTHIS BANK ANGLE.MENU PRINCIPAL
  7. 7. THE ELEVATOR SWITCH MAY BE ENGAGED IN ALL PITCH ATTITUDES SINCE THE PITCHCHANNEL COMPUTER ALSO REMAINS IN CONSTANT SYNCHRONIZATION WITH AIRPLANEPITCH ATTITUDE. AUTOPILOT PITCH LIMITS ARE 25 DEGREES PITCH UP, AND 10 DEGREESPITCH DOWN. WHEN THE ELEVATOR SWITCH IS ENGAGED, THE AIRPLANE MAINTAINS THEEXISTING PITCH ATTITUDE. ENGAGING THE AUTOPILOT AT ATTITUDES EXCEEDING THE 25DEGREE PITCH UP OR 10 DEGREE PITCH DOWN LIMITS IS NOT RECOMMENDED. HOWEVER,IF ENGAGED, THE AIRPLANE RETURNS TO THE MAXIMUM PITCH UP OR PITCH DOWN LIMIT.MENU PRINCIPAL
  8. 8. C IS THE CORRECT ANSWER.MENU PRINCIPAL
  9. 9. WITH FORCE APPLIED TO THE CONTROL WHEEL, THE AILERON ENGAGE SWITCH WILL NOTMOVE FROM THE DISENGAGE POSITION. IF FORCE IS APPLIED TO THE CONTROLCOLUMN, THE ELEVATOR ENGAGE SWITCH WILL NOT MOVE FROM THE DISENGAGEPOSITION. (pause3) NOW, LETS DISCUSS MANUAL MANEUVERING OF THE AIRPLANE WITHAUTOPILOT ENGAGED.MENU PRINCIPAL
  10. 10. THE USE OF THE CONTROL WHEEL AND CONTROL COLUMN FOR MANUAL AUTOPILOTMANEUVERING IS CALLED CONTROL WHEEL STEERING, OR C-W-S. CONTROL WHEELMOVEMENT FOR ROLL MANEUVERS IS TRANSMITTED TO THE AILERON CHANNEL.CONTROL COLUMN MOVEMENT FOR PITCH MANEUVERS IS TRANSMITTED TO THEELEVATOR CHANNEL. THE FORCES TO MOVE THE WHEEL AND COLUMN OUT OF THEIRCENTER POSITIONS ARE SLIGHTLY MORE THAN WITH THE AUTOPILOT DISENGAGED.MENU PRINCIPAL
  11. 11. WHEN THE AUTOPILOT IS ENGAGED, THE CONTROL WHEEL AND COLUMN HAVE ANEUTRAL OR DETENT POSITION. TO MOVE THE CONTROL WHEEL OUT OF THE NEUTRALPOSITION REQUIRES 4 POUNDS OF PRESSURE. TO MOVE THE CONTROL COLUMNREQUIRES 5 POUNDS OF PRESSURE. THESE FORCE LEVELS ARE CALLED LOW DETENT.THE LOW DETENT LEVEL GUARDS AGAINST UNINTENTIONAL PITCH OR ROLL INPUTS.MOVEMENT OUT OF THE DETENT POSITION PRODUCES ROLL OR PITCH IN THE DESIREDDIRECTION.MENU PRINCIPAL
  12. 12. WHEN OPERATING THE AUTOPILOT WITH ADDITIONAL SUBMODES ENGAGED, FOREXAMPLE, HEADING SELECT OR ALTITUDE HOLD, THE FORCE REQUIRED TO MOVE THECONTROL WHEEL INCREASES TO 8 POUNDS AND THE CONTROL COLUMN INCREASES TO18 POUNDS. THIS FORCE LEVEL IS CALLED HIGH DETENT, AND GUARDS AGAINSTINADVERTENT DISENGAGEMENT OF THE SUBMODES. IF A HIGH DETENT LEVEL ISEXCEEDED, THE SUBMODE IN THAT AXIS TRIPS OFF, AND THE AUTOPILOT REVERTS TOCONTROL WHEEL STEERING AT THE LOW DETENT LEVEL. (pause4) NOW LETS LOOK ATOPERATION IN THE MANUAL MODE.MENU PRINCIPAL
  13. 13. RECALL THAT THE AUTOPILOT MODE SELECTOR IS SPRING LOADED TO THE MANUAL MODE.WHILE IN THE MANUAL MODE, THE HEADING SUBMODE MAY BE USED THROUGH USE OF THEHEADING SWITCH. WHEN THE HEADING SWITCH IS IN THE CENTER POSITION, REFERRED TOAS THE HEADING HOLD POSITION, AIRPLANE HEADING IS CHANGED BY CONTROL WHEELSTEERING. IN THIS SUBMODE, C-W-S IS IN LOW DETENT. WHEN PRESSURE IS RELEASEDFROM THE CONTROL WHEEL AT BANK ANGLES LESS THAN 5 DEGREES, THE AIRPLANE WILLROLL WINGS LEVEL. WHEN C-W-S IS USED TO APPLY MORE THAN 5 DEGREES ANGLE OFBANK, UP TO 32 DEGREES OF BANK, THIS BANK ANGLE IS MAINTAINED WHEN PRESSURE ISRELEASED FROM THE CONTROL WHEEL.MENU PRINCIPAL
  14. 14. THE HEADING SELECT FUNCTION IS ACTIVATED BY POSITIONING THE HEADING SWITCH TOHEADING SELECT. THE SWITCH IS MAGNETICALLY HELD IN THIS POSITION. THE C-W-SFORCE LEVEL FOR ROLL CHANGES TO HIGH DETENT.MENU PRINCIPAL
  15. 15. IN HEADING SELECT, THE CAPTAIN MAY THEN ADJUST THE AIRPLANE BY ROTATING THEHEADING SELECTOR ON HIS HSI THE AIRPLANE TURNS TO AND MAINTAINS THE SELECTEDHEADING. THE MAXIMUM BANK ANGLE USING THE HEADING SELECT MODE IS 25 DEGREES.MENU PRINCIPAL
  16. 16. TO DISENGAGE THE HEADING SELECT MODE, MOVE THE SWITCH BACK TO THE CENTER,OR HEADING HOLD POSITION. (pause2) APPLYING MORE THAN THE HIGH DETENT FORCELEVEL WILL OVERRIDE THE HEADING SELECT MODE, AND THIS WILL ALSO RESULT IN THESWITCH MOVING BACK TO THE CENTER HEADING HOLD POSITION, BUT WILL RESULT INA MINOR, BUT ABRUPT ROLL MOTION, WHICH IS FELT THROUGHOUT THE AIRPLANE.MENU PRINCIPAL
  17. 17. POSITIONING THE HEADING SWITCH TO HEADING [`]OFF DISABLES THE WINGS LEVELINGFEATURE. THIS ENABLES THE AUTOPILOT TO MAINTAIN BANK ANGLES OF LESS THAN FIVEDEGREES WHEN PRESSURE IS RELEASED FROM THE CONTROL WHEEL. HEADING [`]OFF ISONLY OPERABLE IN THE MANUAL MODE. IN HEADING OFF, THE FORCE LEVEL REMAINS INTHE LOW DETENT AND THE SWITCH REMAINS ENGAGED DURING CONTROL WHEELSTEERING INPUTS. THE SWITCH WILL TRIP TO THE CENTER POSITION IF ANY MODE OTHERTHAN MANUAL IS SELECTED.MENU PRINCIPAL
  18. 18. B IS THE CORRECT ANSWER.MENU PRINCIPAL
  19. 19. CONTROL WHEEL FORCE ABOVE HIGH DETENT TRIPS THE HEADING SWITCH TO THECENTER POSITION AND THE CONTROL WHEEL FORCE LEVEL CHANGES FROM HIGH TOLOW DETENT.MENU PRINCIPAL
  20. 20. THE PITCH MODE SELECTOR MAY BE USED IN THE MANUAL MODE. RECALL THAT THEPITCH MODE SELECTOR IS SPRING LOADED TO THE [`]OFF POSITION. IN THE OFFPOSITION, PITCH CHANGES ARE MADE BY EXERTING FORCE ON THE CONTROL COLUMNAND RELEASING THE FORCE WHEN THE DESIRED ATTITUDE IS OBTAINED. THE FORCEREQUIRED TO MOVE THE CONTROL COLUMN IS A MINIMUM OF FIVE POUNDS. THIS FORCELEVEL IS LOW DETENT.MENU PRINCIPAL
  21. 21. WHEN ALTITUDE HOLD IS SELECTED, THE AUTOPILOT CAPTURES AND MAINTAINS THEBAROMETRIC ALTITUDE AT THE TIME OF SWITCH SELECTION. PITCH ATTITUDE ISCONTROLLED AUTOMATICALLY. THE CONTROL WHEEL STEERING FORCE LEVEL BECOMESHIGH DETENT. THIS REQUIRES A MINIMUM OF EIGHTEEN POUNDS OF FORCE ON THECONTROL COLUMN TO OVERRIDE THE ALTITUDE HOLD POSITION.MENU PRINCIPAL
  22. 22. THE NORMAL METHOD OF DISENGAGING ALTITUDE HOLD IS TO POSITION THE PITCH MODESELECTOR TO OFF. THIS IS MORE DESIRABLE THAN OVERRIDING THE HIGH LEVELDETENT, BECAUSE THE OVERRIDE METHOD RESULTS IN A MINOR BUT ABRUPT PITCHMOTION WHICH IS FELT THROUGHOUT THE AIRPLANE.MENU PRINCIPAL
  23. 23. SELECTING THE TURBULENCE POSITION REDUCES OR SOFTENS PITCH AND ROLLCOMMANDS AND SHOULD BE USED WHEN FLYING IN ROUGH OR TURBULENT AIR. THECONTROL WHEEL STEERING FORCE LEVEL IS LOW DETENT FOR PITCH. RECALL, IT TAKES5 POUNDS OF FORCE TO MOVE THE CONTROL COLUMN IN LOW DETENT. WITHTURBULENCE SELECTED, THE HEADING SELECT MODE MAY BE USED; HOWEVER, THEMAXIMUM BANK ANGLE THE AUTOPILOT WILL COMMAND IS 8 DEGREES.MENU PRINCIPAL
  24. 24. BECAUSE THE MAXIMUM BANK ANGLE IN THE TURBULENCE MODE IS EIGHT DEGREES,THIS POSITION MAY BE UTILIZED DURING CLIMB OR DESCENT, ALONG WITH THE HEADINGSELECT SWITCH POSITION, TO ACHIEVE A GENTLE TURN TO THE DESIRED HEADING ASSELECTED ON THE CAPTAINS HSI.MENU PRINCIPAL
  25. 25. ONCE TURBULENCE IS SELECTED, IT WILL NOT MOVE AUTOMATICALLY TO OFF. TOCANCEL THE TURBULENCE MODE, THE PILOT MUST SELECT OFF, OR DISENGAGE THEAUTOPILOT.MENU PRINCIPAL
  26. 26. IF THE MODE SELECTOR IS IN AUTO APPROACH OR MANUAL GLIDE SLOPE ANDTURBULENCE IS SELECTED, THE MODE SELECTOR WILL MOVE TO MANUAL. WHEN THEPITCH SELECTOR IS IN TURBULENCE, THE MODE SELECTOR WILL NOT HOLD IN AUTOAPPROACH OR MANUAL GLIDE SLOPE.MENU PRINCIPAL
  27. 27. ANSWER C IS CORRECT.MENU PRINCIPAL
  28. 28. WITH THE PITCH MODE SELECTOR IN ALTITUDE HOLD, C-W-S IS IN THE HIGH DETENTLEVEL. ANY CONTROL COLUMN FORCE WHICH EXCEEDS THIS HIGH DETENT WILL CAUSETHE SELECTOR TO TRIP TO THE [`]OFF POSITION.MENU PRINCIPAL
  29. 29. IN REGARD TO ANSWER AA, (pause2) THE MODE SELECTOR IS SOLENOID HELD IN THERADIO MODES, AND SPRING LOADED TO MANUAL. HOWEVER, CONTROL WHEEL STEERINGIN PITCH WILL NOT CAUSE THE SELECTOR TO TRIP FROM THE VOR-LOC MODE.MENU PRINCIPAL
  30. 30. IN REGARD TO ANSWER B (pause2) RECALL THAT ONLY LOSS OF THE NECESSARYINTERLOCKS WILL CAUSE THE AUTOPILOT CHANNELS TO DISENGAGE. CONTROL WHEELSTEERING IS POSSIBLE ONLY WITH THE AILERON AND ELEVATOR SWITCHES ENGAGED,AND NO LEVEL OF FORCE IS SUFFICIENT TO CAUSE THESE ENGAGE SWITCHES TODISENGAGE.MENU PRINCIPAL
  31. 31. A IS THE CORRECT ANSWER.MENU PRINCIPAL
  32. 32. THE TURBULENCE POSITION CAN BE SELECTED IN ANY MODE. HOWEVER, THE MODESELECTOR WILL TRIP TO MANUAL FROM ANY POSITION EXCEPT VOR-LOC WHEN A VORFREQUENCY IS SELECTED.MENU PRINCIPAL
  33. 33. LETS REVIEW THE MANUAL MODE OF OPERATION. THE MODE SELECTOR MUST BE INMANUAL TO ENGAGE THE AUTOPILOT. THE MANUAL MODE IS USED TO MAKE PITCH ANDROLL CHANGES WITH CONTROL WHEEL STEERING. IN THE MANUAL MODE ALL THEPOSITIONS OF THE HEADING SWITCH AND THE PITCH MODE SELECTOR MAY BE USED.EXCEEDING THE C-W-S HIGH DETENT FORCE OVERRIDES THE HEADING SELECT ANDALTITUDE HOLD SUBMODES. (pause4) LETS NOW DISCUSS THE VOR-LOC MODE OFOPERATION.MENU PRINCIPAL
  34. 34. THE VOR-LOC MODE IS USED TO INTERCEPT AND TRACK VOR RADIALS AND FOR NOGLIDESLOPE LOCALIZER APPROACHES. HEADING AND PITCH SUBMODES MAY BE USEDWHILE OPERATING IN THE VOR-LOC MODE.MENU PRINCIPAL
  35. 35. IN THE VOR-LOC MODE, THE AUTOPILOT USES INPUTS FROM THE CAPTAINS HSI, ANDFIRST OFFICERS RMI. THESE INPUTS []ARE. FROM THE CAPTAINS HSI: (pause1) AIRPLANEPOSITION RELATIVE TO THE DEVIATION BAR, AND COURSE FROM THE TRACK SELECTEDWITH THE WHITE COURSE CURSOR BAR. (pause3) FROM THE FIRST OFFICERS RMI:(pause1) COMPASS HEADING INFORMATION.MENU PRINCIPAL
  36. 36. APPROACH PROGRESS DISPLAYS, LABELED A-P FOR AUTOPILOT, ARE LOCATED ON THECAPTAINS AND FIRST OFFICERS PANELS. THEY ANNUNCIATE THE ARMED AND CAPTUREPHASES OF AUTOPILOT OPERATION IN THE RADIO MODES. THE AUTOPILOT DISPLAYLIGHTS ANNUNCIATE ARMED AND CAPTURE PHASES SIMILAR TO THE FLIGHT DIRECTORDISPLAY LIGHTS.MENU PRINCIPAL
  37. 37. THE LIGHTS FUNCTION IN VOR-LOC, AUTO APPROACH AND MANUAL GLIDE-SLOPE MODES.WHEN AUTO APPROACH MODE IS SELECTED, BOTH THE VOR-LOC AND GLIDE-SLOPELIGHTS ILLUMINATE AMBER, INDICATING THE ARMED PHASE. IF THE VOR-LOC MODE ISSELECTED, ONLY THE VOR-LOC LIGHTS ILLUMINATE. THE SAME LIGHTS ILLUMINATEGREEN INDICATING THE CAPTURE PHASE OF A VOR OR LOCALIZER COURSE AND GLIDESLOPE. WHEN MANUAL GLIDE SLOPE IS SELECTED, THE GLIDE SLOPE LIGHTS ILLUMINATEGREEN IMMEDIATELY. IF THE LOCALIZER HAS NOT BEEN CAPTURED, THE VOR-LOC LIGHTSWILL ILLUMINATE AMBER.MENU PRINCIPAL
  38. 38. LETS SET UP THE AUTOPILOT TO INTERCEPT THE SELECTED INBOUND COURSE, SO THATTHE FLIGHT PATH IS INBOUND ON THE 270 DEGREES RADIAL. (pause2) OUR DISCUSSIONWILL UTILIZE THE CAPTAINS HSI AND THE NUMBER ONE VHF NAV RADIO, BECAUSE IT ISTHE NUMBER ONE COMPASS, AND NUMBER ONE RADIO, THAT FEEDS THE AUTOPILOT.MENU PRINCIPAL
  39. 39. FIRST, SELECT THE APPROPRIATE VOR, OR ILS FREQUENCY. NEXT, SELECT THE DESIREDCOURSE BY ROTATING THE COURSE SELECTOR KNOB ON THE CAPTAINS HSI, SO THATTHE WHITE COURSE CURSOR BAR IS SET TO THE DESIRED COURSE, AND OBSERVE THATTHE DIGITAL COURSE READOUT CONFIRMS THE DESIRED COURSE. THE 0 9 0 DEGREECOURSE IS SELECTED TO ENABLE THE TWO SEVEN ZERO DEGREE RADIAL TO BE FLOWNINBOUND. ALTITUDE HOLD IS OPTIONAL, AND MAY BE USED IN VOR-LOC MODE WITHALTITUDE HOLD SELECTED. PITCH MANEUVERS WILL BE AT HIGH DETENT LEVEL.MENU PRINCIPAL
  40. 40. POSITION THE MODE SELECTOR TO VOR-LOC AND OBSERVE THE A-P ANNUNCIATORILLUMINATES AMBER. THIS MEANS THE AUTOPILOT IS ARMED TO CAPTURE THE RADIAL.CAPTURE WILL OCCUR ONLY WHEN THE AIRPLANE IS MANEUVERED TO WITHINAPPROXIMATELY TWO DEGREES OF THE DESIRED RADIAL. TO TURN THE AIRPLANE TO THEDESIRED INTERCEPT HEADING OF 045 DEGREES, YOU MAY EITHER USE CONTROL WHEELSTEERING, OR, WITH THE ORANGE HEADING TRIANGLE SET TO 045 DEGREES, POSITION THEHEADING SWITCH TO HEADING SELECT, AND THE AIRPLANE WILL TURN TO THE INTERCEPTHEADING, AS DEPICTED ON THIS SLIDE. (pause2) WITH THE HEADING SWITCH IN HEADINGSELECT, THE ROLL AXIS IS IN HIGH DETENT FOR CONTROL WHEEL STEERING.MENU PRINCIPAL
  41. 41. THE AIRPLANE IS NOW IN THIS POSITION. IT IS INBOUND ON A ZERO FOUR FIVE DEGREEHEADING TO THE SELECTED RADIAL.MENU PRINCIPAL
  42. 42. THE AUTOPILOT IS NOW CONTROLLING THE AIRPLANE ON A HEADING OF ZERO FOUR FIVEDEGREES BY USE OF THE ORANGE HEADING CURSOR, AND THE HEADING SELECTSUBMODE. THE MAXIMUM BANK ANGLE IN HEADING SELECT IS TWENTY-FIVE DEGREES.(pause2) THE MODE SELECTOR SWITCH IS IN VOR-LOC AND THE ANNUNCIATOR IS AMBERINDICATING THE AUTOPILOT IS ARMED FOR CAPTURE. (pause2) ALTITUDE HOLD ISSELECTED TO MAINTAIN A CONSTANT ALTITUDE, BUT IT IS NOT A REQUIREMENT FORCAPTURING THE RADIAL.MENU PRINCIPAL
  43. 43. THE AIRPLANE HAS NOW REACHED THE POSITION FOR CAPTURE.MENU PRINCIPAL
  44. 44. WHEN THE AIRPLANE REACHES TWO FIFTHS OF A DOT DEVIATION AS INDICATED ON THEHSI, WHICH IS APPROXIMATELY TWO DEGREES FROM THE DESIRED RADIAL, THEAUTOPILOT WILL CAPTURE THE SELECTED INBOUND COURSE. (pause2) THE HEADINGSWITCH AUTOMATICALLY TRIPS TO HEADING HOLD, AND THE VOR-LOC ANNUNCIATORCHANGES TO GREEN, WHICH IS THE PILOTS INDICATION OF CAPTURE. DURING THECAPTURE PHASE, THE MAXIMUM BANK ANGLE IS TWENTY-FIVE DEGREES.MENU PRINCIPAL
  45. 45. THE AIRPLANE HAS INTERCEPTED THE SELECTED COURSE AND IS TRACKING INBOUND.MENU PRINCIPAL
  46. 46. THE WHITE TWO FROM INDICATOR CONFIRMS THAT THE VOR STATION IS AHEAD OF THEAIRPLANE. (pause2) WHEN THE AIRPLANE IS ON COURSE, THE AUTOPILOTAUTOMATICALLY CORRECTS FOR DRIFT WITH A MAXIMUM BANK ANGLE OF EIGHTDEGREES. IN THIS EXAMPLE, TEN DEGREES OF DRIFT CORRECTION IS BEING MAINTAINED.(pause3) BOTH PITCH AND ROLL ARE IN HIGH DETENT FOR CONTROL WHEEL STEERING.MOVEMENT OF THE CONTROL WHEEL BEYOND HIGH DETENT WILL TRIP THE MODESELECTOR TO THE MANUAL POSITION. MOVEMENT OF THE CONTROL COLUMN BEYONDHIGH DETENT WILL TRIP THE PITCH SELECTOR TO OFF.MENU PRINCIPAL
  47. 47. AS THE AIRPLANE REACHES THE CONE OF CONFUSION IT MAINTAINS HEADING UNTIL OUTOF THE CONE OF CONFUSION AND THEN AGAIN PICKS UP THE SELECTED OUTBOUNDCOURSE OF ZERO NINE ZERO.MENU PRINCIPAL
  48. 48. THE AIRPLANE HAS PASSED THE STATION AND IS TRACKING OUTBOUND ON THE 090 RADIAL, STILL MAINTAINING THE 10DEGREE DRIFT CORRECTION (pause2). FOR COURSE CHANGES GREATER THAN TWENTY DEGREES, CONTROL WHEELSTEERING IS RECOMMENDED. THIS IS BECAUSE THE AUTOPILOT WILL OTHERWISE REMAIN IN THE ON-COURSECAPTURE CONDITION, AND IN THIS CONDITION THE MAXIMUM BANK ANGLE IS EIGHT DEGREES. SUCH A SHALLOW BANKANGLE IS USUALLY NOT ACCEPTABLE TO AIR TRAFFIC CONTROL. (pause2) REMEMBER THAT IN THE VOR-LOC ON-COURSE CAPTURE MODE, THE C-W-S IS IN THE HIGH LEVEL DETENT, AND OVERRIDING THIS DETENT BY USING THECONTROL WHEELWILL RESULT IN A MINOR BUT ABRUPT ROLL MOTION WHICH IS FELT THROUGHOUT THE AIRPLANE.THE RECOMMENDED PROCEDURE IS TO POSITION THE MODE SELECTOR TO MANUAL. THEN C-W-S IS AVAILABLE IN THELOW DETENT LEVEL AND THE AIRPLANE CAN BE TURNED TO INTERCEPT THE NEW COURSE RADIAL. (pause2) FORCOURSE CHANGES OF TWENTY DEGREES OR LESS, THE AUTOPILOT MAY BE LEFT IN THE VOR-LOC ON-COURSECAPTURE MODE. HEADING CHANGES REQUIRED TO INTERCEPT THE NEW RADIAL WILL BE ACCOMPLISHED WITH AMAXIMUM BANK ANGLE OF EIGHT DEGREES, AND BECAUSE THE AUTOPILOT REMAINS IN THE CAPTURE MODE, ANYWIND DRIFT CORRECTIONS WILL STILL BE APPLIED DURING THE MANEUVERING TO ESTABLISH THE AIRPLANE ON THENEW RADIAL.MENU PRINCIPAL
  49. 49. C IS THE CORRECT ANSWER.MENU PRINCIPAL
  50. 50. RECALL THAT WHEN THE HEADING SWITCH IS IN HEADING SELECT, CONTROL WHEELSTEERING BEYOND HIGH DETENT TRIPS THE HEADING SWITCH TO THE CENTER POSITION.THE HEADING SWITCH ALSO TRIPS TO THE CENTER POSITION AT VOR CAPTURE WHERE ITPICKS UP VOR RADIO SIGNALS FOR AUTOMATIC MANEUVERING.MENU PRINCIPAL
  51. 51. THIS COMPLETES PART THREE OF AUTO FLIGHT. GO ON TO THE LAST PART.RETURN TO MENURETURN TO MENUMENU PRINCIPAL
