the ILS frequency (step #4 below), automatic selection of
“VLOC” does not occur.
DO NOT USE FOR
NAVIGATION
1. Within 31 nautical miles of KFLG, the unit
switches from en route mode to terminal mode
and the CDI scale transitions from 2.0 to 1.0
nautical miles, full scale deflection.
2. If you haven’t already activated the approach
(in the steps on the previous page), be sure
to do so when cleared for the approach. See
“Approaches with Procedure Turns” in this
section, step #4 for a description of this opera-
tion.
3. As you approach the IAF (SHUTR), a waypoint
alert (“Left to 032° in x sec”) appears in the
lower right corner of the screen.
As you approach the IAF, “Left to 032° in
x sec” appears, followed by “Left to 032°
now” when it’s time to begin the turn to the
outbound course.
4. If you haven’t already done so, press the VLOC
flip-flop key to activate the ILS frequency.
If you forget this step, the unit displays a
reminder message (within 2 NM of the FAF)
to activate the ILS frequency.
5. As the distance (DIS) to the IAF approaches
zero, the alert is replaced by a turn advisory
(“Left to 032° now”).
6. Fly the outbound course (030°), keeping the
needle centered on the external CDI (or HSI).
7. Once you have flown approximately one minute
past SHUTR intersection, the alert message
“Right to 075° in x sec” appears in the lower
right corner of the screen (if you haven’t
already begun the procedure turn).
