Altitude encoders translate the altitude of the aircraft in 100-foot
increments to a specific code that is transmitted by the transponder
to the Air Traffic Controller, shown next to the aircraft symbol and
transponder code. The Shadin Avionics Falcon Encoder provides automatic
altitude data to GPS and Loran receivers, along with Mode C encoder and
high resolution serializer functions in one compact unit. The Shadin
Avionics encoder meets TSO requirements, helps the GPS to maintain accurate
3-D position calculation, and substitutes fourth satellite altitude reference.
The Shadin Avionics encoder feeds gray code altitude information to
the transponder. It simultaneously feeds RS-232 altitude data to the
GPS and the Shadin Avionics Altitude Management System (AMS-2000) for
Instantaneous Vertical Speed calculation, The AMS-2000 has an innovative
fixed time-based (not fixed altitude) warning as the target altitude
is approached. This means the alert is given earlier at higher rates
of vertical speed for a smoother level off, allowing 20 seconds to level
off, regardless of the rate of climb or descent. The addition of the
Shadin Avionics Encoder enables an enhanced, high resolution 10 foot
resolution to be displayed on your AMS-2000 Altitude.
