The GDL 39/39R automatically adjusts its Traffic Advisory (TA) sensitivity level to
reduce the likelihood of nuisance TA alerts during various phases of flight. TAs are
issued for traffic when they are predicted to be within a specified volume of airspace
around your aircraft in a specified amount of time. The protected volume and time
interval varies based on the current geodetic altitude and groundspeed. Thus, the
protected volume of airspace increases with altitude and ground speed. Refer to the
following table for details.
Altitude
(Geodetic)
Below 5,000
5,000-10,000
10,000-20,000
20,000-42,000
Above 42,000
