50 Cards in this Set

  • Front
  • Back
Altitude alerting inhibited when...
Wing flaps are 25 or greater or while glideslope is captured.
Warning systems priority
1. GPWS Windshear
2. PWS Warnings
3. PWS Cautions
4. Terrain Warnings
PWS enabled when...
Generates cautions and warnings when...
below 2300' RA
below 1200' RA
When is PWS operative?
PWS switch on wx rad control panel must be on. It is activated when:
There is engine oil pressure (either engine) and a transponder is selected on.
Airspeed is >60kts and altitude is below 2300'RA
weather radar is transmitting
PWS inhibited on takeoff when:
new caution alerts between 80kts and 400'RA
new warning alerts between 100kts and 50'RA.
Inhibits do not remove cautions/warnings achieved before inhibit airspeed
PWS inhibited on approach to landing when:
new cautions below 400' RA and new warnings below 50' RA
PWS Caution Description
windshear detected between .5 NM and 3 NM forward and 25 deg L/R of mag hdg.
PWS Warning Description (Takeoff)
windshear detected between .5 NM and3 NM (1.5 airborne) forward and .25NM L/R of mag hdg.
PWS Warning Description (Landing)
windshear detected between .5 and 1.5 NM forward and .25 NM L/R of mag hdg. 1.5 range begins to decrease at 370' AGL until .5 NM and warnings are prohibited at 50'AGL
PWS can't necessarily detect...
-closer than 10 seconds
-very dry microbursts
-other forms like gust fronts
Inputs to Stall Warning System (7)
AOA vanes
Flap position
N1 and N2
air/ground sensor
leading edge flaps
Takeoff Warning Horn sounds when (5)...
-STAB TRIM is not in TAKE-OFF range (green band)
-SPEED BRAKE lever is not in DOWN detent
-Trailing edge flaps are not in the takeoff range (1 through 15)
-Leading edge flaps are not extended
-Parking Brake is set
Takeoff warning horn is same as...
Horn that sounds when cabin pressure reaches 10,000'
TCAS range changes in Normal, Dense and Extremely Dense traffic areas
TCAS number of intruders tracked?
up to 30
Which IRU gives pitch and roll inputs for radar antenna stab?
L IRU (R IRU is backup)
What happens to weather updates if Captain and FO range is set differently?
Occur half as often?
What happens if wx radar autotilt is not available?
Amber NO AUTOTILT on screen. Put switch in manual and msg goes away. Use manual for storm or terrain characteristics.
When amber ALTITUDE ALERT Light illuminated?
900 feet of selected altitude, tone.
Ground Proximity Panel INOP light on?
(some or all GPWS alerts are not available. GPWS alerts which do occur ARE valid)
-GPWS computer malfunction or power loss.
-Invalid inputs received from VHF NAV receiver, air data computer, or radio altimiter, IRS, FMC, stall warning systems or EFIS control panel.
-SYS TEST button (on panel) has been pressed
Ground Proximity Panel SYS TEST button does what?
-causes BELOW G/S, PULL UP, and INOP lights to illuminate, "GLIDESLOPE, PULL UP" and windshear aurals to sound and windsear alert on EADI to illuminate. Terrain aural sounds, and if WxR/TERR selected on EFIS, get a EGPWS terrain test grid display.
When is Ground Prox SYS TEST inhibited?
Between liftoff and 1000' RA or with landing flaps SELECTED.
What does red PULL UP warning light indicate?
-excessive descent rate
-excessive terrain closure rate
-altitude loss after t/o or g/a
-unsafe terrain clearance when not in landing configuration
What does BELOW G/S amber alert light indicate?
-airplane more than 1.3 dots below gs
-inhibits or cancels below glideslope alerting if pushed when below 1000' RA
1Rearmed by climbing above 1000' RA.
FLT CONT Annunciator Light caused by?
Caution on flight control panel:
-LOW QUANTITY (standby hydraulic)
-LOW PRESSURE (A or B flight control and/or standby hudraulic)
-FEEL DIFF PRESS (elevator feel system)
-SPEED TRIM FAIL (dual channel)
-MACH TRIM FAIL (dual channel)
-AUTO SLAT FAIL (dual channel)
(single channel will illuminate FLT CONT when panel is recalled, but MCL press will ext light with only single channel failure)
IRS annunciator light indicates?
Caution condition exists on IRS panel:
FUEL annunciator light indicates?
-FWD and AFT fuel pump LOW PRESSURE lights for tank 1 or 2
-LEFT and RIGHT center tank fuel pump LOW PRESSURE lights with both pump switches ON.
-one center tank fuel pump LOW PRESSURE light on with only one pump switch on.
FUEL annunciator light when panel is recalled means?
-FWD or AFT fuel pump LOW PRESSURE light on for tank 1 or 2.
-One center tank fuel pump LOW PRESSURE light illuminated with both center tank switches ON
-one center tank switch OFF, one ON
ELEC Annunciator Light?
APU annunciator Light
OVHT/DET Annunciator Light DOES NOT go on if:
-amber engine FAULT
REVERSER light causes ENG annunciator light if?
