Data Flags

Data flags appear on the left side of the display to notify

you when there is a loss of reported information. The data

usually displayed, such as lightning or nearby terrain, may

still exist, but may not be displayed for technical reasons.

For instance, when the amber TRAF data flag appears it

means that the MX20 is not receiving Traffic information.

Traffic may be present, but will not be displayed.

POS No valid position information is available from

the source. Do not expect a valid position

representation on the maps. The Ownship

symbol will have an “X” through it.

RTE No valid route (flight plan) is available from the

external navigation source. Route (flight plan)

information will not be shown on the maps.

ALT No valid altitude information is available from

the external source. Altitude related functions

will not operate, such as terrain awareness.

TRAF No traffic information is received from the

external source. Traffic will not be displayed.

Your position information will not be broadcast

in ADS-B capable systems.

LT No valid lightning detection information is

being received from the external source.

Strike and cell information will not be

displayed.

TER Terrain coverage is not available for some part

of the terrain advisory coverage area. Terrain
