WARN_001
Recall RWS indications during takeoff (after nose strut extension) or approach and landing:
- Increasing Performance - Amber “WINDSHEAR” on both PFD and glareshield. - NO aural warning.
- Decreasing performance - Red “WINDSHEAR” on both PFD and glareshield. - Aural warning tone and three cycles of “WINDSHEAR”.
WARN_011
Recall RWS guidance during takeoff (after nose strut extension):
- Increasing performance - When “WIND SHR” is displayed on FMA pitch window, pitch guidance is available through the autopilot and/or F/D. - “WIND SHR” flashes 5x on FMA, then becomes steady. - The roll window will remain unchanged.
- Decreasing performance - When “WIND SHR” is displayed on the FMA pitch window, pitch guidance is available through the autopilot and/or F/D - “WIND SHR” flashes 5x on FMA, then becomes steady. - Windshear roll guidance (wings level) is provided on F/D and “HDG HLD” will be displayed on FMA.
WARN_014
Recall RWS guidance during approach or landing:
- Increasing performance - Guidance is not activated during approach mode unless TOGA button is pressed or either engine EPR is within 95% of the max go-around EPR limit. - w/ TOGA selected, or power at 95% of max go-around EPR limit, windshear guidance is available through autopilot and/or F/D. - When “WIND SHR” is displayed on FMA pitch window, pitch guidance is available through autopilot and/or F/D. - “WIND SHR” flashes 5x on FMA, then becomes steady. - The roll window will remain unchanged.
- Decreasing performace - Guidance is not activated during the approach mode unless the TOGA button is pressed or either engine EPR is within 95% of the maximum go-around EPR limit, windshear guidance is available through the autopilot and/or F/D. When “WINDSHR” is displayed on the FMA pitch window, pitch guidance is available through the autopilot and/or F/D. “WIND SHR” will flash five times on the FMA and then become steady. Windshear roll guidance (wings level) will be provided on the F/D and “HDG HLD” will be displayed on the FMA.
WARN_002
Recall how to silence the overspeed warning system:
- The CAWS will generate a “clacking” sound, alternating with spoken words “overspeed” or “slat overspeed” (as applicable).
- Warning indications remain active and cannot be silenced until overspeed condition is corrected.
WAN_004
Discuss the function of the Pitch Limit Indicator (PLI):
- The PLI appears when airplane reaches 60 KIAS and the airplane is at or below 1500 AGL.
- If the slats are extended, the PLI will be displayed at any altitude.
- PLI indicates relationship of airplane angle of attack and stick shaker angle of attack.
WARN_005
Identify where TCAS target symbology is displayed:
• Symbology is displayed on TA/VSI Indicator and the Pedestal Radar.
WARN_006
Locate where TCAS RA guidance is displayed:
TCAS RA guidance is displayed on the Outer Rose of TA/VSI indicator and through Voice Alerts.
WARN_007
Explain the symbol/color of a TCAS TA:
An aural alert “TRAFFIC, TRAFFIC,” calls attention to a display of a solid amber circle on the TA/VSI Indicator and Pedestal Radar if Mode Selector is in TCAS or WX/TCAS. Additionally, relative altitude with a climb or descent arrow may be present.
WARN_008
Explain the symbol/color of a TCAS RA:
- An RA is displayed as a solid Red Square on the traffic display, and colored arcs are added on the TA/VSI.
- These arcs identify desired vertical rates which will satisfy altitude separation standards.
WARN_013
Describe the TCAS RA maneuver guidance:
- If maneuvering is required, disengage the autopilot and autothrottle.
- Smoothly adjust pitch and thrust to achieve/maintain the vertical guidance indicated by the green band on the TA/VSI. Follow the planned lateral flight path unless visual contact with the conflicting traffic requires other action.
WARN_009
Recall the purpose of GPWS and the types of alerts it provides:
The GPWS alerts the crew when any one of the following occurs:
- Excessive descent rate, “SINK RATE, SINK RATE,”
- Excessive terrain closure rate, “TERRAIN, TERRAIN,”
- Altitude loss after takeoff or go-around, “DON’T SINK, DON’T SINK,”
- Unsafe altitude while not in the landing configuration, “TOO LOW GEAR” or, “TOO LOW FLAPS,”
- Descent below glide slope (below 1,000’ AGL), “GLIDELOPE, GLIDESLOPE,”
- Descent below Decision Height, “MINIMUMS, MINIMUMS.”
Note: The “MINIMUMS, MINIMUMS” vocal is inhibited below 50±15 feet. Consequently, when the DH is set to 50 feet, the “MINIMUMS” vocal may be heard only once or not at all. This has no effect on the DH light which has a much closer tolerance.
WARN_010
Recall when PWS alerts are available on takeoff or approach:
- PWS is active regardless of weather radar switch position on the Weather Radar Indicator. The crew is alerted by way of annunciation and audio announcement.
- During takeoff and landing new PWS CAUTION alerts are inhibited between 80 knots and 400’ RA, and new WARNING alerts between 100kts and 50’RA.
- Below 2,300 feet RA windshear operations use an alternate scan technique for radar and windshear detection.
- Windshear operation is transparent to the crew unless an alert is issued, however crews may notice that the radar update rate could be delayed by as much as 12 seconds due to sharing of processing between windshear and radar. NOTE: If radar is in a non weather mode (OFF or TCAS only mode), the reaction time is greatly reduced.
- The PWS automatically begins scanning for windshear on the ground when:
- The right throttle is set for takeoff. CAUTION: Advancement of the right throttle beyond 2 1/8 units (approx. 80% N1) will activate PWS on the ground.
- One engine is running.
- The PWS automatically begins scanning for windshear in the air when:
- Below 2,300 feet RA (predictive windshear alerts are issued below 1,200 feet RA).
WARN_012
Explain the meaning of the different colors displayed by the EGPWS:
- Magenta: No terrain data available.
- Dotted Green: Terrain from 2,000 below to 500 below (250 with gear down) the airplane’s current altitude.
- Dotted Amber: Terrain 500 feet below (250 with gear down) to 2000 above airplane’s current altitude.
- Dotted Red: Terrain more than 2000 above the airplane’s current altitude.
- Solid Amber: Caution Terrain (approx 60 seconds from impact).
- Solid Red: Warning Terrain (approx 30 seconds from impact).
WARN_016
Recall the conditions that will activate the landing gear configuration warning system with the gear not down and locked:
- Gear handle not down and flaps extended beyond 26 degrees (not silenceable).
- Gear handle not down. Any throttle fully retarded, with airspeed less than 210kts and altitude less than 1500 RA.
WARN_017
Recall indications when approaching an MCP selected altitude:
750 feet above/below the selected altitude, the CAWS generates the ‘C’ chord tone and the altimeter altitude advisory light comes on steady.
WARN_018
Recall the indications when departing an MCP selected altitude:
Departing an MCP selected altitude by more than 250’, a steady ‘C’ chord sounds with an aural “ALTITUDE” and flashing altitude advisory light.
Recall inhibit features associated with the fuel system or the GPWS:
- The OAP message “CENTER FUEL PRESS LO” is inhibited when flaps greater than or equal 6 degrees.
- GRD PROX WARN Switch OVRD inhibits “TOO LOW FLAPS” aural warning when landing is made with less than normal landing flap configuration.
- BELOW G/S Switchlight – Push to inhibit/cancel the “GLIDE SLOPE” warning below 1000’ RA.
- EGPWS OVRD Switchlight – White when pushed inhibits look-ahead terrain alerts and terrain display.
- GPWS is inhibited below 50’ (+/- 15’).
