B 737NG Warning systems.

  1. 1. B 737 NG Ground School. See the aircraft study guide at www.theorycentre.comThe information contained here is for training purposes only. It is of a general nature it isunamended and does not relate to any individual aircraft. The FCOM must be consulted forup to date information on any particular aircraft.
  2. 2. B737-800WARNING SYSTEMS.
  3. 3. Introduction.Aural, tactile and visual warning signals alert the flight crew to conditions requiring actions orcaution in the operation of the aircraft. The character of the signal varies depending upon thedegree of urgency or hazards involved. Aural, tactile and visual warnings are used singularly orin combination to simultaneously provide both warnings and information regarding the natureof the condition.
  4. 4. STICK SHAKER
  5. 5. Conditions which require the immediate attention of the crew are indicated by RED Warninglights in the area of the pilots Primary field of vision.These light indicate engine, wheel well, cargo or APU Fires. Auto pilot and Auto throttledisconnects and Landing Gear unsafe conditions.
  6. 6. Conditions which require the immediate attention of the crew are indicated by RED Warninglights in the area of the pilots Primary field of vision.These light indicate engine, wheel well, cargo or APU Fires. Auto pilot and Auto throttledisconnects and Landing Gear unsafe conditions.Conditions which require the timely attention of the crew are indicated by AmberCaution lights.
  7. 7. BLUE LIGHTS INDICATE: Electrical power AVAILABILITY, STATUS, VALVE POSITIONBlue lights are for information and do not require immediate crew attention.Some blue lights Valve OPEN/CLOSEDindicate valve in transit DIM BLUEBRIGHT BLUE
  8. 8. GREEN LIGHTS Indicate afull extended or commanded position or condition

  16. 16. PRESS either Master Caution light to reset the system.
  17. 17. PRESS either Master Caution light to reset the system.The FAULT light remainsilluminated until the faultis corrected.
  18. 18. RECALL PRESS either annunciator light panelAll lights will illuminate.
  19. 19. RECALL PRESS either annunciator light panel All lights will illuminate.ANY EXISTING FAULTS WILL REMAIN DISPLAYED WHEN RELEASED!
  20. 20. SINGLE FAILURE RECALLSPEED TRIMGPSPSEUThe above HAVE 2 SYSTEMS.Failure of 1 system will not affect safe flight. (Thesecond system will automatically take over)The crew are not shown a single failure except onRECALL.
  21. 21. SINGLE FAILURE RECALLThis light will only show when RECALL is selected.Single failure is indicated if the fault light extinguishes when the Caution iscancelled. If the fault light remains on then both systems have failed. SPEED TRIM GPS PSEU The above HAVE 2 SYSTEMS. Failure of 1 system will not affect safe flight. (The second system will automatically take over) The crew are not shown a single failure except on RECALL.
  22. 22. Mach/Airspeed Warning SystemTwo independent Mach/airspeed warning systems provide a distinct auralwarning, a clacker, any time the maximum operating airspeed of Vmo/Mmo isexceeded. The warning clackers can be silenced only by reducing airspeed belowVmo/Mmo. Vmo is 340 Knots and Mmo is M 0.82The airspeed indicator displays red warning bands indicating maximum andminimum airspeeds. Amber bands indicate maximum and minimum maneuveringairspeeds. The top of the lower amber band indicates the minimum maneuverspeed. It is the slowest speed that provides full maneuvering: 0.3 g maneuvermargin (40° bank) to stick shaker (below approximately 20,000 ft.) or initial buffet(above approximately 20,000 ft.).When either an overspeed condition or a system test occurs, the ADIRU transmitsa signal to the aural warning module, sounding the clacker. The system can onlybe tested on the ground.
  23. 23. AFT OVERHEAD PANELMACH AIRSPEED WARNING TEST Switches
  24. 24. AFT OVERHEAD PANELMACH AIRSPEED WARNING TEST SwitchesPush – tests respective mach/airspeed warning system• clacker sounds• inhibited air mode.
  25. 25. Stall Warning SystemNatural stall warning (buffet) usually occurs at a speed prior to stall. In someconfigurations the margin between stall and natural stall warning is less thandesired. Therefore, an artificial stall warning device, a stick shaker, is used toprovide the required warning.The stall warning “stick shaker” consists of two eccentric weight motors, one oneach control column. They are designed to alert the pilots before a stall develops.The warning is given by vibrating both control columns. The system is armed inflight at all times. The system is deactivated on the ground.Two independent, identical stall management yaw damper (SMYD) computersdetermine when stall warning is required based upon:• alpha vane angle of attack outputs• ADIRU outputs• anti–ice controls• wing configurations• air/ground sensing• thrust• FMC outputs.The SMYD computers provide outputs for all stall warning to include stick shakerand signals to the pitch limit indicator and airspeed displays and the GPWSwindshear detection and alert.Two test switches are installed in the aft overhead panel. Pushing either of theseinitiates a self–test of the respective stall warning channel. The No.1 activates theCaptain stick shaker, and the No. 2 activates the F/O stick shaker. Either stickshaker vibrates both columns through column interconnects.
  26. 26. STALL WARNING TEST Switches
  27. 27. STALL WARNING TEST SwitchesPush – on ground with AC power available: each test switch tests its respective stallmanagement yaw damper (SMYD) computer. No.1 SMYD computer shakes Captain’s controlcolumn, No.2 SMYD computer shakes First Officer’s control column. Vibrations can be felt onboth columns• inhibited air mode.
  28. 28. Intermittent Cabin Altitude/Configuration WarningThe takeoff configuration warning is armed when the airplane is on the ground andeither or both forward thrust levers are advanced for takeoff. An intermittentwarning horn sounds if:• trailing edge flaps are not in the flaps 1 through 25 takeoff range, or• trailing edge flaps are in a skew or asymmetry condition, or haveuncommanded motion, or• leading edge devices are not configured for takeoff or have uncommandedmotion, or• speed brake lever is not in the DOWN position, or• spoiler control valve is open providing pressurized hydraulic fluid to theground spoiler interlock valve, or• parking brake is set, or• stabilizer trim not set in the takeoff range.The Cabin Altitude Warning Horn activates when cabin altitude exceeds 10,000feet. An intermittent warning horn is heard. The Cabin Altitude Warning Hornmay be silenced by momentarily pressing the ALT HORN CUTOUT switch on theCabin Altitude Panel.WARNING: The Cabin Altitude and Takeoff Configuration Warningsuse the same intermittent tone when activated.
  29. 29. Takeoff Configuration Warning Light (As Installed)Illuminated (red) –• activates on the ground as the throttles are advanced if theairplane is not configured correctly for takeoff• activation is simultaneous with aural warning intermittent horn forTAKEOFF CONFIGURATION alert.
  30. 30. Cabin Altitude Warning Light (AS INSTALLED)Illuminated (red) –• illuminates at 10,000 feet if the cabin has not been pressurized• illuminates during flight when loss of cabin pressure occurs• activation is simultaneous with aural warning intermittent hornfor CABIN ALTITUDE alert.

  81. 81. Predictive Windshear Display and Annunciations
  82. 82. Windshear AlertsWindshear alerts are available during takeoff, approach, and landing:• The GPWS provides a warning when the airplane is in a windshear.• The weather radar provides alerts for excessive windshear ahead of the airplane.These are “predictive windshear alerts.”Windshear warnings are accompanied by WINDSHEAR on the attitude indicatorsand voice aural alerts.Windshear cautions are accompanied by a voice aural alert.Windshear alerts are prioritized based on the level of hazard and the required flightcrew reaction time.Predictive windshear alerts are inhibited by an actual windshear warning (airplanein windshear), look-ahead terrain alerts, or radio altitude based alerts.
  83. 83. Predictive Windshear AlertsThe weather radar uses radar imaging to detect disturbed air prior to entering a windshear.Note: The weather radar provides windshear alerts for windshear eventscontaining some level of moisture or particulate matter.Note: The weather radar detects microbursts and other windshears with similarcharacteristics. The weather radar does not provide alerting for all types ofwindshear. The flight crew must continue to rely on traditional windshearavoidance methods.The weather radar automatically begins scanning for windshear when:• thrust levers set for takeoff, even if engine is off or IRS not aligned, or• in flight below 2,300 feet RA (predictive windshear alerts are issuedbelow 1,200 feet RA).Alerts are available approximately 12 seconds after the weather radar beginsscanning for windshear. Predictive windshear alerts can be enabled prior to takeoffby pushing the EFIS control panel WXR switch.
  84. 84. PREDICTIVE WINDSHEAR WARNING DURING TAKEOFF
  85. 85. Predictive Windshear InhibitsDuring takeoff and landing, new predictive windshear caution alerts are inhibitedbetween 80 knots and 400 feet RA, and new warning alerts between 100 knots and 50 feet RA.These inhibits do not remove existing predictive windshear alerts. If a warning/caution eventoccurs before those boundaries, it will remain on thedisplay and the complete aural callout will be annunciated.
