Annunciations
Advisory flags, data flags, and messages appear on the display to give information about the status of the MX20
or to provide operating information.
Advisory Flags
Annunciations will appear on the upper left side of the display to provide advisories for Traffic, Terrain, and
Lightning. Advisory information is monitored and displayed regardless of the selected function. Advisory flags
will flash for approximately 10 seconds when they first appear and then turn solid while they are still valid.
Advisory icons will reduce in size if more than two advisory conditions exist.
ADS-B Traffic
The Traffic advisory flag will appear on the left side of the display when traffic is reported to be within ±2000
feet of your altitude and 5 nm of your location. This Traffic advisory is only available when the ADS-B system
with a UAT data link is installed and operational. Refer to the TIS Traffic section for a description of TIS-A and
TIS-B.
Skywatch/TCAD/TIS-A Traffic
The Traffic Advisory/Alert will appear in amber on the left side of the display when the traffic sensor indicates
an alerting condition. Refer to the TIS Traffic section for a description of TIS-A and TIS-B.
Terrain
The Terrain advisory flag will appear on the left side of the display when the terrain surface or obstacle altitude
is within approximately 500 feet of your altitude and within approximately two minutes of flight in any direc-
tion.
Lightning
The Lightning advisory flag will show on the left side of the display when the WX500 sends an indication that
lightning has been detected within 50 nm of your location. See the WX500 manual for details about range and
