Surveillance Flashcards
What systems are installed on the T3CAS?
TCAS
TERRAIN
TRANSPONDER
Red square?
TCAS RA
RA aural inhibited?
An RA is inhibited below 1100 ft climbing or below 900 ft descending (AGL).
Amber circle
TA
“TRAFFIC TRAFFIC” Aural warning
No PFD indications
On the GPWS panel, if the TERR pb is selected OFF, what indications/alerts will be operative/inhibited?
Predictive GPWS alerts are inhibited
Basic GPWS alerts remain operative
How many GPWS modes
5 modes
1 - excessive rate of descent
2 - excessive terrain closure
3 - altitude loss after takeoff
4 - unsafe terrain clearance (not in ldg config)
5 - descent below G/S
When are PWS aural and visual alerts available?
Below 1200ft (AGL)
At takeoff, inhibited above 100kts until 50ft after takeoff
At landing, inhibited below 50ft
What system provides the windshear detection function (reactive windshear)?
FAC
Flight Augmentation Computer
PWS operates below what altitudes?
2300ft RA
What indications when a GPWS mode 2 (Excessive terrain closure rate) CAUTION is generated?
“TERRAIN…” aural alert sounds
GPWS amber light is illuminated
When are PWS (predictive windshear) alerts inhibited?
At takeoff, above 100 kt and up to 50 ft.
During landing, below 50 ft.
By reactive windshear detection and aural messages of stall warnings.
Aural alerts of the PWS have priory over what?
TCAS, GPWS and other FWC aural warnings
On the GPWS panel, if the SYS pb is selected OFF, what indications/alerts will be operative/inhibited?
All basic GPWS alerts remain inhibited
Predictive GPWS alerts are operational
When is the reactive windshear function available?
At takeoff, 3s after liftoff, up to 1300 ft RA
At landing, from 1300 ft RA to 50 ft RA
With at least CONF 1 selected
