a battery backed up calendar/clock. In addition, once a satellite
is being tracked, the KLX 135A’s system time is automatically
updated to UTC (Zulu) time. However, if the time displayed on
the Initialization page or the SET 2 page is in error by more than
10 minutes it is necessary to enter a correct time. See steps 5
and 6 in section 3.2, “Turn-On And Self Test.”
4. The aircraft’s position should be within 60 nm of where the
KLX 135A last had a valid position. If the distance is greater than
60 nm the KLX 135A’s position should be “initialized” on either
the Initialization Page (section 3.2), or the SET 1 page. Since the
KLX 135A stores its position when power is removed, it is usually
not necessary to initialize the position when power is later reap-
plied. However, initialization may be required, for example, if the
KLX 135A was not turned on for a flight or if it stopped navigating
somewhere along the last flight or if it stopped navigating some-
where along the last flight due to a lack of adequate satellite
coverage. If there is any doubt about whether or not to initialize,
go ahead and do it! It’s no big deal and it takes just a moment.
To initialize the position from the SET 1 page:
1. If the cursor is not on the screen
(figure 3-57), press the
B
button to bring it on the page over
the INIT POS field (figure 3-58).
2. Using the right inner and outer
knobs, enter the identifier for the
airport where you are presently
located or the identifier of a
navaid or other airport which is
close to your present position (fig-
ure 3-59). Any waypoint in the
data base which is within 60 miles
is acceptable, but the closer the
better. Remember, if you are
entering an airport identifier that
is all letters (no numbers), then it
will begin with a “K” prefix in the
contiguous U.S., a “P” in Alaska
(in some cases; in others, the
prefix is not added), or a “C” in Canada. If there are numbers in
the identifier then a prefix is not used. Outside the contiguous
U.S., Alaska, and Canada, use the airport identifiers as they are
charted.
