page will also instruct you to press
the
E
button if you wish to see the
Airport 4 page (airport communica-
tions) for the primary airport so that
the correct communications frequen-
cy may be determined (figure 3-183).
NOTE: In addition to the message page messages that alert you to
special use airspace, the KLN 35A can also display the five nearest
areas of SUA. It will even give you the direction and distance to the
nearest edge of the SUA. See
The SUA alert feature is three dimensional. The SUA areas are
stored in the KLN 35A data base with regard to altitude when the
actual SUA altitude limitations are charted in terms of mean sea level
(MSL). Therefore, if you are flying either above or below an SUA
area you won’t be inconvenienced with nuisance alert messages.
However, if the actual lower limit of an SUA is charted in terms of an
altitude above ground level (AGL), then it is stored in the KLN 35A as
all altitude below the upper limit of the SUA. If the actual upper limit
of an SUA is charted in terms of AGL, it is stored in the KLN 35A as
“unlimited”.
Since the altitude input to the KLN 35A is pressure altitude from an
altitude encoder, you must manually
update the KLN 35A with an altimeter
setting (baro correction) in order to
receive accurate SUA alerting. You
may easily update the altimeter
setting by selecting the SET 8 page
(figure 3-184) The right inner knob is
used to change the altimeter setting. When the setting is complete,
turn off the cursor.
CAUTION: Failure to keep the altimeter baro setting updated
will result in inaccurate special use airspace alerting. If this fea-
ture is used, it is a good idea to update the altimeter baro setting
on the SET 8 page each time you make a change to an aircraft’s
altimeter setting.
NOTE: If there is no altitude input to the KLN 35A, all altitudes will be
regarded as being within the boundary of the SUA area.
