Flight Procedures

Once the aircraft is airborne (determined by system configuration at the time of installation) the system
switches from standby mode to operating mode. The 400/500 Series unit displays OPER in the upper right
hand corner of the display and begins to display traffic on the Traffic or Map Page.
The TIS Traffic Advisory (TA) should alert the crew to use additional vigilance to identify the intruding
aircraft. Any time the traffic symbol becomes a yellow circle or a voice warning is announced, conduct a
visual search for the intruder. If successful, maintain visual contact to ensure safe operation. See page 5 for
a description of pilot responses to TIS display messages.

After Landing

Once the aircraft is "groundborne" (determined by system configuration at the time of installation)
the system switches from operating mode to standby mode. The 400/500 Series unit displays 'STBY'. As
described previously, both the standby and operating modes can be manually overridden by the display
controls.
