The TRT800A is a standard transponder in 160 mm standard housing for all applications in general aviation from ultralight aircraft to gliders and piston engine aircraft.

It offers the classical A/C modes of operation plus full Mode S support including the future-oriented extended squitter function.

Advantages of this unit are an attractive price, small dimensions and a built-in altitude encoder without heating requirements.

These features help to reduce installation effort, cost and weight. The unit provides the required 25 ft altitude resolution.

The TRT800A may be used up to 35,000 ft actual operating altitude (not to be confused with maximum operating altitude) and a maximum true airspeed of 250 kn (463 km/h).

Using the Remote Control Unit TRT800RT the TRT800A can be fully remotely controlled.
