The TRA-3000 (PMA) has proven
effectiveness in flying search and rescue missions,
forestry operations, pipeline maintenance, offshore
helicopter operations, aero medical emergency services,
border patrol, and electronic news gathering operations.
The TRA-3000 Radar Altimeter provides precise AGL
information from 2500 feet down to 40 feet.
The transmitter/receiver and antennas
fit in a single, lightweight, aerodynamic unit that
can be easily installed on the fuselage bottom or
under the wing. The innovative design reduces the
size and weight of the system and significantly increases
transmitter efficiency.
Coupled with the TRA-3000 Radar
Altimeter, the TRI-40 Indicator displays the AGL altitude
and the pilot’s preselected decision height
(DH) in a bright, LED readout. Through audible warnings,
the pilot is alerted when the aircraft descends below
the DH. This panel-mounted display provides essential
information, especially important when there are insufficient
visual cues in the terminal area surrounding an airport
or along a desired low-level flight path.
The TRI-40 Indicator also includes
a visual and audible gear-up warning when the aircraft
is below 100 feet. A trip-point output allows the
pilot to activate additional alerts every 100 feet
up to 800 feet. As an option, a TRI-40 Indicator mounted
in a round faceplate adapter is available to simplify
certain installations.
In addition to the standard version,
a Night Vision Goggle (NVG) compatible display is
available.
