Unit first to be certified under TSO C146 for precision nav and
approaches

Aviation Technologies has announced the new CNX-80 All-In-One
Integrated Navigation product. This new unit is composed of a
quarter-VGA (320x240) color display, a WAAS GPS system, a built-in
VHF Nav/Com with localizer and glide slope functions, as well as a
series of interfaces, one of which is designed to control the new
SL70R remote Mode A/C transponder.
As opposed to most GPS navigation systems in production today
under TSO C129, which are designed as non-precision secondary
navigation purposes, the new CNX-80 is the first unit worldwide to
be certified under the new TSO C146 for standalone GA primary
precision navigation and approaches.
The augmentation of the GPS capability with the data from the
integrated 15-channel WAAS (Wide Area Augmentation Service) service
receiver will allow the operator of the CNX-80 to use the unit as
primary means of navigation in all phases of flight, including
approaches. Approximated 800 WAAS-augmented LNAV and VNAV
approaches should become available on July 10 of this year, once
the FAA certifies the IOC (Initial Operating Capability) of the
WAAS approach systems.
TSO C146 also specifies that the unit must provide a five hertz
update rate rather than the one hertz update rate required by TSO
C129. This means that the navigation screen must be updated five
times per second rather than once. The unit is also designed to
provide full lateral guidance on all procedures and approaches,
from takeoff to the flare on landing. GPSS steering data is
available for STEC and other types of autopilots; when coupled
through GPSS, the CNX-80 can navigate your aircraft from takeoff
through airways and waypoints, automatically transitioning through
procedure turns or holding patterns to approaches, and will even
execute a full missed approach. Lateral guidance is also provided
for all ARIC 424 leg-types.
Other features of the CNX-80 are voice messaging and audio
alerting, a VHF Nav receiver and 760 channel Com transceiver. The
rear of the unit also features multiple input/output ports for
interfaces to autopilots, CDI's, flight directors, multifunction
display units and the new SL70R remote transponder.
The database for the CNX-80 will be provided by Jeppessen.
Annual updates will be priced at $360 for the first unit, with an
additional update for a second CNX-80 priced at $110.
The unit is expected to start shipping in May of 2003 and have a
MSRP of $11,995.
