What sub-systems make up the Surveillance system?
Terrain Awareness and Warning System (TAWS)
Weather Radar (WXR) system, including the predictive windshear detection
Traffic Collision Avoidance System (TCAS)
Automatic Dependent Surveillance - Broadcast -Traffic (ADS-B Traffic@ )
Transponder (XPDR).
How many surveillance systems are there?
Two identical surveillance systems (SYS 1 and SYS 2)

The crew must manually switch on system 2.
What component parts make up a TAWS system?
A Ground Proximity Warning System (GPWS) function with five basic modes

A TAWS database
Which alerts have priority?
Stall/windshear alerts
or

If the terrain function of the GPWS triggers a warning, how much time has the system calculated before a collision?
