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 5. TCAS |
|
|
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. OR Airspeed is >60kts and altitude is below 2300'RA OR weather radar is transmitting |
|
|
PWS inhibited on takeoff when:
|
new caution alerts between 80kts and 400'RA
and 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 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

|
|
|
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) |

|
|
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?
|

|
|
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. |
|
|
