Alternat gear ext switch is used as directed by the QRH in the event that (757 left) or (767 center) hyd system press is lost.
How do you silence the OVR SPD warning?
All warning indicators remain activated until airspeed is reduced below Vmo/ Mmo.
What conditions will activate the landing gear config warning?
- The landing gear config warning sys alerts the crew that the land gear is not extended for landing. The landing config warning activates if:
The airplane is in flt, and:
- any land gear is not down and locked, and
- either of the following conditions exist:
- flaps in a landing position (25 or 30 - can’t be silenced), or - any thrust lever is at idle w/RA below 800 ft.
What conditions will cause a T/O config Master Warning w/aural warning siren?
The red CONFIG Warning lgt illum’s if:
- Either thrust lever advanced to T/O range on the gnd with:
- Flaps not in T/O position
- Parking brake set
- Spd Brake lvr not down
- Stabalizer not in the green band
Does stall warning sys function during all phases of flt?
What does the Pitch Limit Isolator (PLI) indicator?
Yes it function in all phases of flt.
PLI
- it indicates the pitch limit at which stick shaker activation will occur.
Where is TCAS target symbology displayed?
Where is TCAS RA guidance displayed?
TCAS symbology:
- on the VSI if selected
- on the RADAR display if selected
TCAS RA guidance:
- on the periphery of the VSI
- an aural voice sounds
- TCAS RA symbology (RED SQUARE) appears on the TA/VSI
What symbol/color represents a TA?
What symbol/color represents a RA?
TA: filled amber circle
RA: filled red square
GPWS provides alerts for potentially hazardous flight conditions involving imminent impact with the gnd. The GPWS alerts the crew when any one of the following occurs?
- excessive descent rate, “sink rate”
- excessive terrain closure rate, “terrain”
- altitude loss after T/O or Go- around, “don’t sink”
- unsafe alt while not in the landing config, “too low gear” or “ too low flaps”
- descent below G/S, “glide slope”
- descent below DH, “minimums”
- EGPWS “terrain” warning (red) indicates 20-30 secs from projected impact.
- EGPWS “caution terrain” (Amber) indicates 40-60 secs from projected impact w/terrain
When are Predictive Wind-shear (PWS) caution and warning alerts available on T/O or APP?
Alerts are automatically enabled below 1200’ AGL. The PWS mode is automatically enabled when:
- on the gnd and the thrust lvr’s are set for T/O
- in flt, the acft is below 2300’ AGL (this is when the sys becomes enabled, but alerts cannot be received until 1200’ AGL).
When are Reactive Wind-shear (RWS) alerts are available?
Explain the meaning of the different colors displayed by the EGPWS in the terrain alerting display?
RWS
- at rotation below 1500’ RA
EGPWS
- RED and Amber represent terrain conflicts if flt continues toward the terrain. Solid RED is an imminent threat. These are known as “look ahead” conflicts.
How do you display terrain info oh the HSI?
Select TERR on the EFIS control panel and verify blue TERR on the HSI or the white TERR discrete lgt (as installed). Available in MAP, EXP VOR and ILS or APP modes.
When are the MASTER WARNING, MASTER CAUTION and associated aural warning’s inhibited? (Note: EICAS and indicator lgts are not inhibited)
Caution inhibit begins @80 kts and continues until the first to occur: 400’ AGL or 20 secs elapsed time following nose gear extension. Caution is also with both eng’s shutdown.
Warning inhibit begins at nose gear ext during rotation and continues until the first to occur: 400’ AGL or 20 secs elapsed time following nose gear extension.
Recall and locate the following EICAS indications: warning, caution, advisory, and status message?
- Warning are displayed on the top of the EICAS in RED
- Cautions are displayed below warnings in Amber
- Advisories are displayed below cautions and are identified 1 character to the right.
- A status que in blue on the top left corner of the lower EICAS screen means status messages which haven’t been viewed are on the status page. The status messages may be viewed by selecting the display status switch. These are sys faults affecting airplane dispatch and are not considered crew alerts.
What do EICAS status messages indicate?
Status Messages
- identify system faults affecting airplane dispatch and aren’t considered crew alerts. The messages are displayed on the EICAS STATUS page on the lower EICAS screen.
Note: EICAS STATUS messages may be erased on the gnd prior to dispatch w/logbook entry req’d. If they cannot be erased, they must be addressed.
Function of the EICAS Caution Cancel and Recall switches?
Cancel Switch
- PUSH - displays the next page of EICAS messages when additional pages exist.
- CANCELS Caution and advisory messages when the last page is displayed. Note: warning messages remain. Note: Common messages remain.
RECALL SWITCH
- PUSH - displays the previously cancelled EICAS messages, if the associated condition(s) still exist.
- Displays the first page of messages when multiple pages exist.
Function of the gnd prox G/S INHB switch?
Gnd Prox Glide Slope Inhibit (GND PROX G/S INHB) switch
- PUSH - inhibits the gnd prox glide slope caution when below 1000’ radio altitude.
Function of the GND PROX FLAP OVRD switch?
Ground Proximity Flap Override (FLAP OVRD) switch
- PUSH (OVRD Visible)
- inhibits the gnd prox too low flaps caution
- inhibits the gnd prox too low terrain caution
Note: pushing the GND PROX FLAP OVRD switch to OVRD inhibits the alert, when the alert is due to flap not in landing position.
Function of the Gnd Prox/Gear Config OVRD switch?
Gnd Prox Gear Override (GEAR OVRD) switch:
- PUSH - (OVDR visible)
- inhibits the gnd prox TOO LOW GEAR caution
- inhibits the gnd prox TOO LOW TERRAIN caution
- inhibits the landing gear config warning siren
Note: Pushing the GND PROX GEAR OVRD switch to OVRD inhibits the alert, when the alert is due to gear not down.
Function of the EGPWS OVRD / TERR OVRD switch (as installed)?
Gnd Prox Terrain Override (TERR OVRD) switch
- PUSH (OVRD visible) - inhibits look ahead terrain alerts and displays.
Meaning of the ALT ALERT lgt on fwd center panel?
Altitude Alert (alt alert) lgt - illum'd (Amber) - between 250-300' and 750-900' deviation from selected altitude depending on ship number.
