No-Bearing TAs
If the bearing of a TA target cannot be determined, a No-Bearing TA will be
issued. No-Bearing TAs are typically displayed as a yellow text banner on the
traffic display. The text typically includes “TA” followed by the distance, relative
altitude, and vertical trend arrow. Relative altitude and vertical trend arrow are
not available for targets without altitude reporting.
