Gordon Pratt has a bit of bragging to do at this year's NBAA show.
Pratt, president of Boise, Idaho-based Chelton Flight Systems
(Booth 4159), comes to the show with two "world's firsts"
certifications under his belt-the world's first synthetic vision
EFIS in January and the world's first GPS-WAAS navigator in March.
Both firsts are packaged together in the company's FlightLogic
Synthetic Vision EFIS, which will be at the show for pilots to
ooh and aah over both in real-time simulator format and the real
thing in Chelton's demonstration aircraft.
"The system is STC'd for installation on virtually any Part
23 aircraft from Piper Cubs to Citations," crows Pratt, adding
that the company received approval for helicopter installations
in May. Pratt says the FlightLogic EFIS includes real-time forward-looking
terrain, Class A, B and C TAWS, Class A and B helicopter TAWS,
conformal traffic display, a highway-in-the-s
The basic system includes two 6.25 x 5.5-inch full-color, sunlight-readable
LCDs acting as the primary flight display (PFD) and the multifunction
display (MFD). The hardware includes an inertial AHRS with non-tumbling
solid-solid state angular sensors and accelerometers as well as
magnetometers, a remote-mounted Air Data Computer with digital
fuel flow, and 12-channel GPS/WAAS receiver.
The PFD can be used to display the 3-D highway-in-the-sky, terrain modeling
including towers and obstructions, traffic (with Ryan TCD), enhanced
low-speed awareness cues, an unusual attitude recovery mode and
an on-screen full-function FMS. The MFD has a moving map display
using Jeppesen NavData, full weather graphics, TAWS, wind aloft
and waypoint information.
Chelton says the system is TSO'd and STC'd for installation in
over 650 different models of aircraft.
