AURAl AleRTS
A TA consists of a displayed traffic symbol (solid yellow circle) and an aural alert.
The aural alert announces "traffic", followed by the intruder aircraft' s position, altitude
relative to own aircraft ("high", "low", or "same altitude"), and distance from own
aircraft; e.g. "traffic, 12 o'clock, high, 3 miles".

Self-TeST
The GTS 8XX automatically performs a self-test upon power up. The self-test
checks internal parameters and calibrates components of the GTS 8XX. The self-test
can also be initiated by the user during normal operation.
Check for the following test criteria on the Traffic Page during power-up:
• If the GTS 8XX passes the power-up test; and the aircraft both has a squat
switch and is on the ground, the Standby Screen is displayed (Figure 2).
• If the GTS 8XX passes the power-up test and the aircraft both has a squat
switch and is airborne, the Traffic Page is displayed on the 6-nm display range
and in the normal altitude display mode.
• If the GTS 8XX passes the power-up test and the aircraft does not have a squat
switch, the Standby Screen is displayed (Figure 2).
• If the GTS 8XX fails the power-up test (as indicated by a FAILED screen),
the GTS 8XX is inoperable, see the GTS 8XX Installation Manual for detailed
information on Failure Response.
NOTE: The FAILED message is displayed when the system detects an error
that prohibits further traffic display operation.
NOTE: When the system is in standby, the GTS 8XX does not transmit,
interrogate, or track intruder aircraft.
