Surveillance Flashcards
Recall the function of the GPWS TERR pb and SYS pb when selected OFF
TERR pb selected OFF
-inhibits only the terrain wanting feature of the GPWS
SYS pb selected OFF
-Inhibits each of the basic categories of the GPWS system. The terrain warning feature remains fully operational
Describe the function of the G/S MODE pb on the GWPS Panel
-Inhibits the excessive deviation below the glides-lope warning “GLIDESLOPE”
-Used for approaches with glideslope out of service, or LDA/LOC approaches
Describe the function of the FLAP MODE pb on the GWPS Panel
-inhibits the unsafe terrain clearance warnings “TOO LOW FLAPS”
-Used in conjunction with a flap malfunction
Describe the function of the LDG FLAP 3 pb on the GWPS Panel
-configures the GPWS to expect FLAPS 3 as the final flap setting for landing
-inhibits “TOO LOW FLAPS” aural warning
-Landing memo displays FLAP 3 CONF 3 instead of FLAPS FULL
Explain the manual operation of the GPWS terrain feature
-A TERR ON ND pb has been selected ON (green)
-Terrain is continuously displayed on the respective ND
Explain the automatic operation of the GPWS terrain feature
-respective TERR ON ND pb is deselected (light out)
-terrain is automatically displayed on both NDs as the result of a caution or warning
-Both TERR ON ND pb illuminate ON (green)
-to remove the terrain display, the pb must be deselected
How do you control of the brightness of EGWPS terrain
Outer knob of the ND brightness control knob controls the brightness of both weather radar and EGPWS terrain displays
Recall the details of the terrain and weather indications on the NDs
-When terrain is being displayed, TERR (blue) appears in the lower right corner of the ND
-When weather radar is on TILT (blue) with the corresponding tilt angle appears in the lower right corner of the ND
Recall the meaning of the number value displayed with the terrain display
-appears only when the respective ND is set in ARC mode
-Represents in the highest elevation of an obstacle that is within the respected NDs range setting
081 is read as 8100 ft
Recall the indications associated with a terrain caution
-Both GPWS lights (amber) illuminate on the forward instrument panel
-Aural “TERRAIN AHEAD” warning sounds
-terrain displays automatically appear on both ENDs
-Amber TERRAIN AHEAD message appears on the NDs
Recall the indications associated with a terrain warning
-both PULL UP lights (red) illuminates on the forward instrument panel
-Aural “TERRAIN AHEAD! PULL UP! warning sounds
terrain displays automatically appear on both ENDs
-Red TERRAIN AHEAD message appears on the NDs
Describe the meaning of the indications given for a TCAS preventative or corrective advisory
Preventative advisory- Keep the aircrafts vertical speed out of the red area of the pfds vertical speed indicator
Corrective advisory- Keep the aircrafts vertical speed within the green shaded area of the PFDs vertical speed indicator
Which ND mode cannot display GPWS, TCAS, or weather radar returns
PLAN mode
Indications of Windshear warnings
-WINDSHEAR (red) message appears on the PFD s
-aural “WINDSHEAR WINDSHEAR” warning sounds
-depending on condition, the airspeed trend arrow may either stagnate or show excessive accelerating trend
NOTE the wind shear system is a reactive system only
NOTE 2 warnings will only function
-when aircraft is configured at flaps 1 or greater
-at low altitudes during takeoff and landing
will not occur at higher altitudes or while in clean configuration
Describe the altitude alerting system altering system indications
Designed to alert the pilot of altitude deviations when an autopilot IS NOT ENGAGED
During a climb or descent, when within 750 ft of the FCU altitude
-a short duration aural C-chord sound
-PFD altitude window bored pulses until within 250 ft of the FCU altitude
In level flight in the aircraft deviates more than 250 ft of the FCU altitude
-a short duration aural C-chord sound
-PFD altitude window bored pulses
