SUPPLEMENT 2
The KNS 80 is a panel mounted navigation system consisting of a
VOR/Localizer Receiver. DME Interrogator, RNAV Computer, and
Glide Slope Receiver in a single unit. When combined with an appropriate
COi Indicator. the unit becomes a complete navigation system featuring
two modes of VOR. two modes of RNAV. and ILS. The unit also simulta-
neously displays distance to station (waypoint). velocity to station (way-
point). time to station (waypoint), and chosen parameter (frequency, radial
or distance) of one of the four waypoints. Separate system flexibility is main-
tained with a DME HOLD button which allows ••freezing" the DME fre-
quency while tuning to a different ILS or VOR frequency. The various
modes. (VOR. VOR PAR, RNV ENR. and RNV APR}. are selected by
pressing the appropriate VOR or RNAV pushbutton. If an 11.S frequency
is placed in the active data, the system will automatically go to the I LS mode.
When switched out of an ILS frequency the system will revert back to the
mode in which it was at the time the ILS frequency was selected.
When energized. the system will go to the mode in which it was when
switched off. In addition. it will retain all waypoint data through a power
shutdown.
Additional features include an automatic dimming circuit to compen-
sate for changes in ambient light level. and a CMOS memory powered by
two silver-oxide watch cells e11abling long terrr. waypoint storage·
(2
years
typical cell life). If the batteries should become we~k. waypoint storage will
be lost and the radio will tune to 110.00 MHz. way point I in USE and DSP.

normally during the flight, but no memory will be retained after turning the
