Warning Systems Flashcards
What does EGPWS stand for?
Enhanced Ground Proximity Warning System
What does TCAS stand for?
Traffic Alert and Collision Avoidance System
The colors associated with the EICAS 4-level alert messaging system are:
Warning - red,
Caution - amber,
Advisory - cyan,
Status - white
True or False: The fixed ELT is located in the Forward EBAY.
False
[Aft Pressure Bulkhead/aft E-Bay]
A root message on the EICAS is indicated by a _____ to the left of the message.
chevron/carot (>)
True or False: A single failure can only generate one EICAS message.
False
True or False: The takeoff configuration warning system provides an aural and visual warning when the aircraft is not in a suitable takeoff configuration
True
True or False: The Forward Looking Terrain Awareness function looks ahead of the aircraft to detect terrain or obstacle conflicts with greater alerting time.
True
Ground Proximity Warning Function has _______ modes and compares aircraft position with a terrain database to provide aural alerts and displays.
7
[7 Modes - Excessive descent rate, excessive terrain closure, altitude loss after takeoff, unsafe terrain clearance, excessive deviation below glideslope, advisory callouts, windshear alerting]
The Terrain Clearance floor function provides an increasing terrain clearance
protection envelope around the airport runway. It is based on the aircraft’s
_______ position, nearest runway, and radio altitude.
present
Terrain mapping is provided by EGWPS and is displayed on the MFD navigation map display selected. __________ means pilots are approximately 30 seconds from impact.
Solid red
Terrain mapping is provided by EGWPS and is displayed on the MFD navigation map display selected. __________ means pilots are approximately 60 seconds from impact.
Solid yellow
Terrain mapping displayed on the MFD is displaying Solid Green. This means
_______.
Highest terrain not within 500 ft (250 ft with gear down)
If the EGPWS or _______ are unavailable, windshear conditions will not be
detected.
Radar Altimeter
The windshear detection system monitors for windshear between 10 and _______ feet radio altitude.
1,500 ft
True or False: If either the EGPWS or radar altimeter are unavailable, windshear conditions will not be detected.
True
When a windshear caution is issued, the following does NOT occur.
–NOT EICAS MESSAGE–
Amber windshear message is displayed on the PFD,
the CAUTION WINDSHEAR alert sounds
The windshear escape guidance system is provided through _______.
The flight director [press TOGA button!!]
During a windshear caution or warning, any flex or de-rated thrust mode is
cancelled by moving thrust levers go to the _______ position.
MAX
True or False: TCAS setup and selections are normally made via the CCD and the EICAS.
False [MFD]
TCAS traffic detected within 2,700 feet vertically and beyond 6.5 nm laterally of the aircraft is displayed as a hollow diamond and is categorized as _______ traffic.
Other
A traffic target that is shown on the TCAS with “-26” associated with it means
_______.
2,600 ft below your altitude
A traffic target that is shown on the TCAS with “+19” associated with it means
_______.
1,900 ft above your altitude
Normally, TCAS TA and RA information is displayed on the _______.
MFD
