Track Angle: The angle of your actual direction of travel. Track angle is computed using the magnetic variation at the Present Position.

Track Angle Error (TAE): The difference between the Desired Track and the Track Angle (Dtk - Trk = Tae). A letter is shown next to the Track Angle Error value showing the direction of error in reference to the current Track.

True North: Geographic north, at the earth’s north pole.

Tower (TWR): Airport tower communication frequency.

UUNICOM: The radio frequencies assigned to aeronautical advisory stations for communication with aircraft. Unicoms may provide such airport information as active runway, wind direction and velocity and other conditions of importance to pilots.

UTC (Universal Time Coordinate): Greenwich Mean Time, or the time at the Prime Meridian in Greenwich, England. Also referred to as Zulu time.
