The height above airport alert feature does
not serve the same function as a radar
altimeter. It does not provide any warning
about the aircraft's actual height above the
airport's surrounding terrain.
The height above airport alert feature will
only be accurate if the barometric altimeter
setting is correct. If the height above
airport function is enabled, ensure the
barometric altimeter setting is correct on
the ALT page.
When the height above airport is enabled, the
KLN 90B creates a 5-nm radius cylinder of airspace
centered on an airport. This airport is any airport that
is a direct to waypoint or is the to waypoint in the
active flight plan. The height of the cylinder above the
airport is the height selected on the SET 5 page. The
KLN 90B adds the selected altitude to the elevation
stored in the database for the airport. The KLN 90B
provides an altitude alert light when the aircraft first
penetrates the cylinder.
To enable or disable the height above the airport
alert, press the left CRSR button. Use the left outer
knob to position the cursor over the enable/disable
field. Turn the left inner knob to select on or off. To
select the height, use the left outer knob to position the
cursor over the altitude field. Turn the left inner knob
to select an offset between 800 and 2000 feet. Press
the left CRSR button to turn off the cursor function.
