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

  20. 20. SINGLE FAILURE RECALL 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.
  21. 21. SINGLE FAILURE RECALL This light will only show when RECALL is selected. Single failure is indicated if the fault light extinguishes when the Caution is cancelled. 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 System Two independent Mach/airspeed warning systems provide a distinct aural warning, a clacker, any time the maximum operating airspeed of Vmo/Mmo is exceeded. The warning clackers can be silenced only by reducing airspeed below Vmo/Mmo. Vmo is 340 Knots and Mmo is M 0.82 The airspeed indicator displays red warning bands indicating maximum and minimum airspeeds. Amber bands indicate maximum and minimum maneuvering airspeeds. The top of the lower amber band indicates the minimum maneuver speed. It is the slowest speed that provides full maneuvering: 0.3 g maneuver margin (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 transmits a signal to the aural warning module, sounding the clacker. The system can only be tested on the ground.
  23. 23. AFT OVERHEAD PANEL MACH AIRSPEED WARNING TEST Switches
  24. 24. AFT OVERHEAD PANEL MACH AIRSPEED WARNING TEST Switches Push – tests respective mach/airspeed warning system • clacker sounds • inhibited air mode.
  25. 25. Stall Warning System Natural stall warning (buffet) usually occurs at a speed prior to stall. In some configurations the margin between stall and natural stall warning is less than desired. Therefore, an artificial stall warning device, a stick shaker, is used to provide the required warning. The stall warning “stick shaker” consists of two eccentric weight motors, one on each 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 in flight at all times. The system is deactivated on the ground. Two independent, identical stall management yaw damper (SMYD) computers determine 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 shaker and signals to the pitch limit indicator and airspeed displays and the GPWS windshear detection and alert. Two test switches are installed in the aft overhead panel. Pushing either of these initiates a self–test of the respective stall warning channel. The No.1 activates the Captain stick shaker, and the No. 2 activates the F/O stick shaker. Either stick shaker vibrates both columns through column interconnects.
  26. 26. STALL WARNING TEST Switches
  27. 27. STALL WARNING TEST Switches Push – on ground with AC power available: each test switch tests its respective stall management yaw damper (SMYD) computer. No.1 SMYD computer shakes Captain’s control column, No.2 SMYD computer shakes First Officer’s control column. Vibrations can be felt on both columns • inhibited air mode.
  28. 28. Intermittent Cabin Altitude/Configuration Warning The takeoff configuration warning is armed when the airplane is on the ground and either or both forward thrust levers are advanced for takeoff. An intermittent warning 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 have uncommanded motion, or • leading edge devices are not configured for takeoff or have uncommanded motion, or • speed brake lever is not in the DOWN position, or • spoiler control valve is open providing pressurized hydraulic fluid to the ground 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 10,000 feet. An intermittent warning horn is heard. The Cabin Altitude Warning Horn may be silenced by momentarily pressing the ALT HORN CUTOUT switch on the Cabin Altitude Panel. WARNING: The Cabin Altitude and Takeoff Configuration Warnings use 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 the airplane is not configured correctly for takeoff • activation is simultaneous with aural warning intermittent horn for TAKEOFF 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 horn for CABIN ALTITUDE alert.
  31. 31. Altitude Alerts Selected Altitude Alert A white box shows around the selected altitude display between 900 feet and 300 feet before reaching the selected altitude. Current Altitude Alert The white box around the current altitude display becomes bold between 900 feet and 300 feet before reaching the selected altitude. The box turns amber and flashes for 300 feet to 900 feet deviation from the selected altitude.

  81. 81. Predictive Windshear Display and Annunciations
  82. 82. Windshear Alerts Windshear 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 indicators and 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 flight crew reaction time. Predictive windshear alerts are inhibited by an actual windshear warning (airplane in windshear), look-ahead terrain alerts, or radio altitude based alerts.
  83. 83. Predictive Windshear Alerts The weather radar uses radar imaging to detect disturbed air prior to entering a windshear. Note: The weather radar provides windshear alerts for windshear events containing some level of moisture or particulate matter. Note: The weather radar detects microbursts and other windshears with similar characteristics. The weather radar does not provide alerting for all types of windshear. The flight crew must continue to rely on traditional windshear avoidance 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 issued below 1,200 feet RA). Alerts are available approximately 12 seconds after the weather radar begins scanning for windshear. Predictive windshear alerts can be enabled prior to takeoff by pushing the EFIS control panel WXR switch.
  84. 84. PREDICTIVE WINDSHEAR WARNING DURING TAKEOFF
  85. 85. Predictive Windshear Inhibits During takeoff and landing, new predictive windshear caution alerts are inhibited between 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 event occurs before those boundaries, it will remain on the display and the complete aural callout will be annunciated.
