Frasca’s CGI system
provides smooth instrument response.
Other systems operate slower resulting in jumpy displays that
are difficult to set or fly. For example turning the OBS knob quickly on
one competitors system results in the OBS display jumping 30 degrees. On
Frasca’s CGI system the OBS smoothly transitions.
Realistic Viewing:
Attempts to electronically simulate mechanical guages using CRT’s
failed due to the curvature of the CRT. This resulted in large gaps
between the bezel and the display. Flat panel displays solved this problem
but introduced an new problem. Many flat panel displays have limited
viewing angles. This makes it difficult or impossible to view displays
from across the cockpit. Frasca’s
CGI technology solves this problem and provides excellent viewing
throughout the cockpit.
Frasca has also
developed real knob technology to provide realistic panel controls
associated with the electronic displays.
For example the altimeter knob used to set the barometric pressure or the
OBS knob on the HSI. Frasca’s real knob technology provides
smooth turning knobs that feel like the aircraft. Knobs with clicks are
not realistic. They give pilots false cues that do not exist in the
aircraft. They also do not allow the pilot to provide precise control ie
very small inputs.
Realistic 3D Bezels:
Realism requires overlay panels with bezels. Knob mechanisms must be
situated between the overlay and the flat panel display. CGI technology
places the LCD panel not more than a quarter of an inch from the front of
the panel.
Frasca devices which have
incorporated CGI include PC-7, B200, and a Model
242R FTDs
