The SUA alert feature may be disabled (or enabled) on
the Setup 8 (SET 8) page, shown in figure 3-129. After
displaying the SET 8 page on the left side, press the left
C to turn on the left cursor function. The left inner knob
is used to display AIRSPACE ALERT ENABLE or AIR-
SPACE ALERT DISABLE.
If the SUA alert feature has been enabled, the KLN 90B
allows you to select a vertical buffer on the SET 8 page
(figure 3-130) in order to provide an additional layer of
protection from inadvertently entering a SUA area. To
select a vertical buffer, make sure the SUA alert feature
has been enabled. Press the left
C to turn on the left
cursor and then use the left outer knob to move the cur-
sor over the first position of the vertical buffer (figure 3-
131). Use the left outer knob to position the cursor and
the left inner knob to select each number (figure 3-132).
The buffer may be selected in one hundred foot incre-
ments. After the desired selection has been made, press
the left
C to turn off the cursor function.
The vertical buffer serves to “stretch” the SUA area in
both directions by the selected buffer altitude. For exam-
ple, let’s say you have selected a buffer of 1000 feet and
the actual SUA area exists from 5,000 feet MSL to 12,000
feet MSL. In this case you will receive SUA alert mes-
sages if you fly at any altitude between 4,000 and 13,000
feet MSL.
CAUTION: It is the pilot’s responsibility to avoid
those areas of special use airspace where ATC clear-
ance to penetrate is required but has not been
obtained. The KLN 90B’s special use airspace alert is
only a tool to assist the pilot and should never be
relied upon as the sole means of avoiding these
areas.
NOTE: Special Use Airspace alerting is disabled when in
the approach arm or approach active modes.
