Transcript

  • 1. MENU PRINCIPAL
  • 2. THE ADVANCED AIRPLANE HAS THE INTERIOR FORWARD AIRSTAIRS CONTROL PANELABOVE THE FORWARD ENTRY DOOR AND FORWARD OF THE ATTENDANTS OXYGENCOMPARTMENT.MENU PRINCIPAL
  • 3. ON THE ADVANCED AIRPLANE, THE SWITCH THAT OPERATES THE STEP LIGHTS ISLOCATED ON THIS CONTROL PANEL.MENU PRINCIPAL
  • 4. THE CONFIGURATION FOR THE BASIC AIRPLANE HAS THE FORWARD AIRSTAIRS CONTROLPANEL ABOVE THE FORWARD ENTRY DOOR, BUT IS LOCATED AFT OF THE PORTABLEEMERGENCY EXIT LIGHTS. THE PANELS ARE THE SAME, EXCEPT THERE IS NO SWITCH FORTHE STEPLIGHTS.MENU PRINCIPAL
  • 5. THE SWITCH FOR OPERATING THE STEP LIGHTS IS ON THE LOWER LEFT CORNER OF THEFORWARD ATTENDANTS PANEL. THE FORWARD ATTENDANTS PANEL IS LOCATED ON THEWINDSCREEN AS YOU ENTER THE PASSENGER CABIN.MENU PRINCIPAL
  • 6. THE STANDBY MODE IS A BACK-UP IN THE EVENT OF FAILURE OF THE STAIRS TO RETRACTOR EXTEND IN THE NORMAL MODE. ON AIRPLANE 701, WHEN USING THE STANDBY MODEONLY, AC POWER IS NOT REQUIRED. HOWEVER, THE BATTERY SWITCH MUST BE ON. ONALL OTHER BASIC AIRPLANES, AC POWER IS REQUIRED FOR BOTH NORMAL ANDSTANDBY MODES, WHEN USING THE INTERIOR CONTROL PANEL.MENU PRINCIPAL
  • 7. THE EXTERIOR CONTROL HANDLE, FOR THE FORWARD AIRSTAIRS, IS IN THE SAMELOCATION ON BOTH THE ADVANCED AND BASIC AIRPLANES. THE OPERATION IS SLIGHTLYDIFFERENT WHEN OPERATING IN THE STANDBY MODE, FOR BASIC AIRPLANES 701, AND702.MENU PRINCIPAL
  • 8. FOR BASIC AIRPLANE 703 THROUGH 707, AND ON THE ADVANCED AIRPLANE, A SWITCH TOOPERATE IN THE STANDBY MODE IS LOCATED WITHIN THE CONTROL PANEL RECESS, ANDIS SPRING LOADED TO THE NORMAL POSITION. THE NORMAL POSITION REQUIRES BOTHAC AND DC POWER. THE STANDBY POSITION REQUIRES DC POWER ONLY, AND THEBATTERY SWITCH MAY BE ON OR OFF.MENU PRINCIPAL
  • 9. THE CONFIGURATION FOR THE BASIC AIRPLANES SEVEN OH ONE AND SEVEN OH TWO,HAS TWO POSITIONS IN BOTH EXTEND AND RETRACT. FOR EXTENDING OR RETRACTINGTHE AIRSTAIRS WITH NO AC POWER IT IS NECESSARY TO GO BEYOND THE NORMALDETENT TO THE STANDBY POSITION, WHICH REQUIRES ADDITIONAL FORCE. WHILE IN THISPOSITION, BATTERY POWER IS USED TO RAISE OR LOWER THE FORWARD AIRSTAIRS.(pause4) NOW, LETS EXAMINE THE CREW AND PASSENGER OXYGEN SYSTEMS.MENU PRINCIPAL
  • 10. THE PASSENGER OXYGEN SYSTEMS ARE VIRTUALLY THE SAME ON BOTH AIRPLANES,WITH ONLY MINOR DIFFERENCES IN THE TYPE OF PASSENGER SERVICE UNIT INSTALLED.MENU PRINCIPAL
  • 11. THE CREW OXYGEN SYSTEM ON THE ADVANCED AIRPLANE HAS A COMBINED MASK-REGULATOR ASSEMBLY CONSISTING OF A HEADPIECE AND A FACE PIECE. THE FACEPIECE CONTAINS A REGULATOR, SUPPLY HOSE, AND MICROPHONE.MENU PRINCIPAL
  • 12. EACH OF THE FOUR CONTROL PANELS HAS A TWO POSITION []ON AND [`]OFF SUPPLYLEVER. THE RECEPTACLE FOR CONNECTING THE OXYGEN MASK, AND THE MICROPHONEJACK, ARE ADJACENT TO THE SUPPLY LEVER. REVIEW THE PROCEDURE FOR CHECKINGTHE OXYGEN SYSTEM IN YOUR OPERATIONS MANUAL.MENU PRINCIPAL
  • 13. ON EARLY AIRPLANES, A QUICK DONNING MASK IS STOWED BELOW EACH REGULATOR.THE MASK ASSEMBLY CONSISTS OF A HEAD PIECE, AND A FACE PIECE. THE FACE PIECECONTAINS A SUPPLY HOSE AND MICROPHONE.MENU PRINCIPAL
  • 14. THERE ARE FOUR CREW OXYGEN REGULATORS IN THE COCKPIT; ONE ABOVE EACH PILOTS SEAT, AND ONE EACHFOR THE TWO OBSERVERS. WHEN THE CREW SHUT-OFF VALVE IS OPEN, OXYGEN FLOWS TO EACH REGULATOR.THE SUPPLY LEVER HAS TWO POSITIONS, ON AND OFF. THE LEVER MUST BE ON BEFORE ANY OXYGEN CAN FLOWTHROUGH THE REGULATOR. A WHITE FLOAT TYPE INDICATOR, ABOVE THE EMERGENCY LEVER, GIVES VISUALASSURANCE THAT OXYGEN IS FLOWING THROUGH THE REGULATOR. THE OXYGEN DILUTER LEVER HAS TWOPOSITIONS: 100 PER CENT, AND NORMAL. WITH THE SUPPLY LEVER ON, BELOW TWENTY-SEVEN THOUSAND FEET,THE NORMAL POSITION PROVIDES A MIXTURE OF COCKPIT AIR AND OXYGEN. ABOVE TWENTY-SEVEN THOUSANDFEET, THE NORMAL POSITION PROVIDES 100% OXYGEN UNDER PRESSURE. WITH THE SUPPLY LEVER OFF, THENORMAL POSITION PROVIDES ONLY COCKPIT AIR TO THE MASK. THE 100% POSITION PROVIDES PURE OXYGEN ATALL FLIGHT LEVELS. A QUANTITY INDICATOR, ABOVE THE SUPPLY LEVER, INDICATES THE QUANTITY REMAINING INTHE CYLINDER WHEN THE SUPPLY LEVER IS PLACED TO THE ON POSITION.MENU PRINCIPAL
  • 15. THE EMERGENCY LEVER HAS THREE POSITIONS; EMERGENCY, NORMAL, AND TEST MASK.WHEN THE LEVER IS IN THE EMERGENCY POSITION, THE REGULATOR PROVIDES ACONTINUOUS FLOW OF 100% OXYGEN UNDER PRESSURE. IN THE NORMAL POSITION, THEOXYGEN DILUTER LEVER CONTROLS THE MIXTURE. THE TEST MASK POSITION IS USED TOCHECK THE SYSTEM AND WILL SUPPLY 100% OXYGEN UNDER PRESSURE WHEN IN THETEST MASK POSITION. REVIEW THE PROCEDURES FOR CHECKING YOUR OXYGEN MASKAND REGULATOR. THIS PROCEDURE IS LISTED IN CHAPTER 3, NORMAL PROCEDURES.MENU PRINCIPAL
  • 16. ON BOTH AIRPLANES, THE PORTABLE CREW OXYGEN CYLINDER IS LOCATED BEHIND THEFIRST OFFICERS SEAT. THE BASIC AIRPLANES DO NOT HAVE THE FULL FACE MASK. THEQUICK DISCONNECT OXYGEN MASK COUPLING IS PROVIDED WITH DEMAND, ANDCONSTANT FLOW, OUTLETS. (pause4) NOW, LETS LOOK AT THE LIGHTING DIFFERENCES.MENU PRINCIPAL
  • 17. ON THE ADVANCED AIRPLANES, CONTROL CABIN LIGHTING INCLUDES TWO WHITE DOMELIGHTS THAT PROVIDE GENERAL ILLUMINATION. THE SWITCH, LOCATED ON THE AFTOVERHEAD PANEL, IS A THREE POSITION SWITCH MARKED DIM, [`]OFF AND BRIGHT.MENU PRINCIPAL
  • 18. WITH THE BATTERY SWITCH IN THE ON POSITION, POWER IS AVAILABLE FOR THE TWOWHITE DOME LIGHTS LOCATED NEAR THE CEILING IN THE CONTROL CABIN.MENU PRINCIPAL
  • 19. THE BASIC OR EARLY 737 AIRPLANES HAVE TWO WHITE AND TWO RED DOME LIGHTS FORGENERAL LIGHTING AND DIFFUSED ILLUMINATION. THE WHITE DOME LIGHTS ARECONTROLLED BY AN ON-OFF SWITCH LOCATED ON THE AFT OVERHEAD PANEL. THEVARIABLE INTENSITY CONTROL FOR THE RED DOME LIGHTS IS MARKED DOME RED.MENU PRINCIPAL
  • 20. THE RED DOME LIGHTS ARE NEAR THE CEILING OF THE CONTROL CABIN, AND ADJACENTTO THE WHITE DOME LIGHTS.MENU PRINCIPAL
  • 21. THE ADVANCED AIRPLANES HAVE HIGH INTENSITY STROBE LIGHTS MOUNTED ON EACH WING TIP,FORWARD OF THE RED AND GREEN POSITION LIGHTS. A TAIL STROBE LIGHT IS MOUNTED ABOVETHE APU EXHAUST. THE STROBE LIGHTS FLASH AT ONE SECOND INTERVALS. THE LIGHTS ARECONTROLLED BY A THREE POSITION SWITCH MARKED STROBE AND STEADY, OFF, AND STEADY,LOCATED ON THE FORWARD OVERHEAD PANEL. PLACING THE POSITION SWITCH TO STROBE ANDSTEADY, TURNS ON THE STROBE LIGHTS AND THE FIXED COLORED NAVIGATION LIGHTS. PLACINGTHE POSITION SWITCH TO STEADY, TURNS ON THE COLORED NAVIGATION LIGHTS, AND THE TWOWHITE, TRAILING EDGE, WINGTIP LIGHTS.MENU PRINCIPAL
  • 22. ON THE BASIC AIRPLANES, WITHOUT THE HIGH INTENSITY STROBE LIGHTS, A THREE POSITIONSWITCH LABELED POSITION, FIXED, OFF, AND OSCILLATING AND FIXED, CONTROLS THENAVIGATION LIGHTS. THE LIGHTS CONSIST OF A COLORED LIGHT ON EACH WING TIP, ONE FIXEDAND ONE OSCILLATING. WHITE LIGHTS ARE MOUNTED ON EACH WING TIP TRAILING EDGE, AND AWHITE OSCILLATING TAIL LIGHT ON THE AFT END OF THE FUSELAGE. THESE AIRPLANES HAVENO NOSE GEAR TAXI LIGHT INSTALLED. POSITIONING THE SWITCH TO FIXED, OR OSCILLATINGAND FIXED, TURNS ON THE FIXED NAVIGATION LIGHTS. THE OSCILLATING LIGHT IS ALSO TURNEDON WHEN OSCILLATING AND FIXED IS SELECTED. NOW, LETS LOOK AT THE PRE-RECORDEDANNOUNCEMENT OPERATION.MENU PRINCIPAL
  • 23. THE ADVANCED AIRPLANE HAS THE PRE-RECORDED ANNOUNCEMENT PANEL ADJACENTTO THE FORWARD ATTENDANTS PANEL. THE PANEL AND BASIC OPERATION IS SLIGHTLYDIFFERENT TO THAT IN THE BASIC AIRPLANE. THE AUTOMATED PA ANNOUNCEMENTSYSTEM IS CAPABLE OF 24 DIFFERENT ANNOUNCEMENTS. FROM THE CONTROL PANEL,THE FLIGHT ATTENDANT CAN SELECT 23 OF THE 24 ANNOUNCEMENTS. ANNOUNCEMENTA1, RAPID DECOMPRESSION, IS ACTIVATED AUTOMATICALLY BE A PRESSURE SWITCH INTHE PASSENGER OXYGEN SYSTEM. IT CANNOT BE SELECTED.MENU PRINCIPAL
  • 24. ON THE BASIC AIRPLANES, SWITCH NUMBER ONE IS THE EMERGENCY ANNOUNCEMENTTHAT WILL BEGIN AUTOMATICALLY WHEN THE PASSENGER CABIN ALTITUDE EXCEEDS10,000 FEET, AND WILL RESET IF THE CABIN ALTITUDE DECREASES BELOW 10,000 FEET.THE EMERGENCY ANNOUNCEMENT ILLUMINATES RED WHEN ACTIVATED AUTOMATICALLY,OR IT MAY BE SELECTED MANUALLY. ONCE THE EMERGENCY ANNOUNCEMENT BEGINS,THE CANCEL SWITCH IS INOPERATIVE. HOWEVER THE PA SYSTEM CAN BE USED TOOVERRIDE AND CANCEL THE ANNOUNCEMENT.MENU PRINCIPAL
  • 25. ON THE ADVANCED 737 AIRPLANES, EACH LAVATORY IS PROTECTED AGAINST FIRE BY ANEXTINGUISHER THAT AUTOMATICALLY DISCHARGES FREON GAS WHEN EXPOSED TOABNORMALLY HIGH TEMPERATURES. THE FIRE EXTINGUISHER IS LOCATED BENEATH THEWASH BASIN IN EACH OF THE LAVATORIES. ON THE BASIC 737 AIRPLANES, THERE ARE NOFIRE EXTINGUISHERS IN THE LAVATORIES.MENU PRINCIPAL
  • 26. RETURN TO MENURETURN TO MENUMENU PRINCIPALTHIS COMPLETES THE DIFFERENCES BETWEEN THE ADVANCED AND BASIC 737AIRPLANES.
