occur if the aircraft is
within approximately two
nautical miles of one of
these areas even if the
aircraft’s projected track
over the ground won’t
actually penetrate the
SUA area (figure 3-203).
If one of the SUA areas
is penetrated, another
message will state:
Inside SUA.
The SUA alert feature may be disabled (or enabled) on the Setup 7
(SET 7) page, shown in figure 3-204.
Select the SET 7 page, turn on the
cursor (
B ). The right inner knob is
used to choose between SUA ALERT
ENABLED and SUA ALERT DIS-
ABLED.
If the SUA alert feature has been
enabled, the KLN 89(B) allows you to
select a vertical buffer on the SET 7
page in order to provide an additional
layer of protection from inadvertently
entering an SUA. To select a vertical
buffer, make sure the SUA alert fea-
ture has been enabled. Turn on the
cursor (
B ) (figure 3-205) and then
use the right inner knob to select the
buffer (figure 3-206). The buffer may
be selected in one hundred foot or ten
meter increments. After the desired
selection has been made, turn the
B off.
The vertical buffer serves to “stretch” the SUA area in both directions
(up and down) by the selected buffer altitude. For example, let’s say
you have selected a buffer of 1,000 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 messages if you fly at any altitude between 4,000
and 13,000 feet MSL.
