NORMAL PROCEDURES
(a)
KNS 80 OPERATION
The KNS 80 can be operated in any one of 3 basic modes:
(a)
VOR,
(b)
RNAV,
or
(c)
ILS. To change from one mode to another,
the
appropriate
pushbutton switch
is
pressed,
except
that the ILS mode
is entered automatically whenever an ILS frequency is channeled
in the USE waypoint.
The display will annunciate
the mode by
lighting
a message
above
the pushbutton. In addition
to the
standard
VOR and RNAV enroute (RNV ENR) modes, the KNS
80 has
a constant course width or
parallel
VOR mode (VOR PAR)
and an RNAV approach mode (RNV
APR). To place the unit
in
either of these secondary modes the VOR
push button
or the RNAV
pushbutton, as the case may be, is
pushed a second time. Repetitive
pushing of the VOR
button
will cause the system to alternate
between
the VOR and VOR PAR modes, while repetitive pushing
of the RNAV button causes the system to alternate between RNV
ENR and RNV APR modes.
