TIS Traffic
Thumbnail
Status
Definition
"Track
Degraded"
The angular placement of intruders
in the traffic thumbnail is not
necessarily within 5 degrees of the
nose. This indication is normal on
the ground in aircraft without a
heading source.
"Pos
Degraded"
The ownship GPS position
accuracy (HFOM, VFOM) is worse
than the normal limits for accurate
placement of intruders. This
indication is normal on the ground
until a good GPS signal is acquired.
"ADS-B
Degraded"
Indicates the receiver has not yet
gotten a good enough GPS lock to
update its internal clock or there is
a problem with the ADS-B
receiver’s GPS position.
"Maint
Required"
This message is sent by the ADS-B
receiver. If displayed, consult the
ADS-B receiver manual.
"No TIS-B"
Indicates the ground is not
providing TIS-B or ADS-R services
to your aircraft. The primary
causes of this are: you are not in
range of a ground station, OR, your
aircraft is not providing qualifying
ADS-B Out information, OR, your
ADS-B In device is not configured
for the correct tail number. If you
never get TIS-B service while in a
known service area, it likely means
there is a misconfiguration of your
ADS-B Out or ADS-B In device.
