| The INS
422 is a high quality, multi-function,
fully integrated navigational instrument
designed as a complete, stand-alone
unit, supplying four basic navigational
aids: VOR with digital course select and Automatic Radial "TO" Centering
feature {DEMO},
Localizer, Glideslope {DEMO}, and Three Light Marker {DEMO}. The units digital
display well define the CDI indications.
CDI output data is also available
at the rear connector for easy interface
with most Autopilots. Aluminum construction
offers a lightweight yet very durable
unit, which will provide years of
reliable service. This instrument
mounts in a standard round 3.125
inch mounting hole.
Automatic Radial
Centering
To determine the bearing TO a VOR
station with conventional course
indicators, it is necessary to manually
rotate the OBS to center the course
deviation pointer. With the Automatic
Radial Centering feature provided
on the INS 422
system, this is done automatically
when the external momentary button
is pushed.
Pushing the remote automatic radial
centering button enables circuitry
to automatically position the digital
CDI indication to provide a one-time
radial "TO" the VOR station. The
digital indications displayed on
the CDI will then return to conventional
operation, permitting the radial
to be flown in a conventional manner.
