EGPWS Flashcards
When testing, anything other than ____ or ___ requires maintenance.
GO or 0s
What does the GPWS fault flag mean?
Fault in the system
What can have the EGPWS overlay?
HSI Arc/ Map Arc
How is EGPWS powered up?
By turning on power from ANY of the FMS MASTER POWER switches
EGPWS provides what type of windshear alerting?
Reactive windshear alerting
What does a yellow WS flag mean?
Reactive windshear is inoperative
On the WX+T display, precipitation and turbulence are displayed, if detected, to a maximum selected range of…
40 NM (Maximum turbulence display range = 40 NM)
If neither pilot nor copilot has terrain overlay selected on an HSI when a terrain awareness display alert is issued, what will occur?
The pop-up feature displays terrain on both pilot and copilot HSIs at a range of 10 NM, with audio alerts.
Which enhancement provides an additional element of protection by alerting the pilot of premature descent for approaches where glideslope is not available?
Terrain Clearance Floor (TCF)
What does it mean if terrain is yellow (light/dark) or red?
That it is above your aircraft
What does it mean if terrain is green or black?
That it is below your aircraft
What does it mean if terrain is magenta?
That it is unmapped
With peaks mode, what additional information is displayed on the HSI in terrain mode?
The highest (and lowest) terrain within the displayed range
In peaks mode, what does the red number indicate?
The highest terrain (1000 = 1000’ MSL)
What does the amber windshear annunciator mean?
Predictive windshear ahead (gain)
What does the red windshear indicator mean?
Loss performance windshear
When does the speedbrake alert become active?
When below 1K’ AGL and speed brakes moved past 2 degrees
What aural warning will you hear if a predictive windshear is encountered on approach?
“Go Around, Windshear Ahead”
What does the aural warning ‘WINDSHEAR x3” mean?
That you are in reactive windshear (loss)
When do you hear the warning “Glideslope, Glideslope?”
When 2 dots or more below the glideslope
You receive the aural “TERRAIN, TERRAIN, PULL UP” warning, how many seconds from the terrain hazard?
30 seconds (warning envelope)
When is it appropriate to use the terrain inhibit (TERR INH) switch?
When landing at an airfield not in the EGPWS database
Why would you want to override speed brakes (by pressing the S/B OVRD switch)?
If the stabilizer is inoperative (jammed)
The FLP OVRD switch overrides the ______ aural alert, which occurs during an approach when flaps are below ____. (Real world example?)
“Too Low, Flaps”, 25 degrees
What technology does the radar use to detect turbulence?
Doppler
Doppler technology is made for…
Turbulence and windshear
Can the radar detect clear air turbulence?
No
Off in the Radar Display indicates…
The RCP is set to OFF
What is the indication that radar has failed?
WXR in black letters on red background
When the radar is in ground map mode, low reflectivity targets such as calm water display as…
Black
What is the function of the Radar Control Panel (RCP) CLTR feature?
Reduces intensity of ground returns while viewing weather displays (Reduces ground clutter)
