BendixKing KLX 135A - Pilots Guide - Manual (Page 92)

NOTE: If there is no altitude input to the KLX 135A, all altitudes will
be regarded as being within the boundary of the SUA area.
Only the outer lateral boundaries are stored for Class B, Class C,
CTA, and TMA airspace. These SUA areas are stored as “cylinders”
of airspace so all altitudes below the upper limit of these areas are
considered to be in the SUA.
The message prompt for a special use airspace alert will occur when
the aircraft’s position is at a point such that a projection of the air-
craft’s existing track over the ground is approximately 10 minutes
from penetrating the
outer boundary of one
of these areas. It will
also 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 actu-
ally penetrate the SUA
area (figure 3-185). 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 3-186. 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 KLX 135A 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 feature has been enabled.
