SETUP 5: Setup 5 Page (SET 5)
Fig3.6
The setup 5 page functions in the Height Above Airport Alert feature of the KLN 90B. The height
above airport alert feature is a feature to alert the user when the aircraft altitude is at a certain
height above (user-entered value), but less than 2000 ft, and within 5 nm of the next active
waypoint. One obvious use of this feature is to be notified when you are at pattern altitude during
an approach. The height above the airport is set on this page, and the feature is also turned on and
off on this page. The height value entered is the actual height above the airport, not the altitude
above MSL. The value entered is added to the altitude of the next active waypoint. A large red "APT
ALERT" annunciation is displayed on the screen when the entered height is reached, and remains on
until the feature is reset or turned off. There are 5 lines of information.
Lines 1 and 2: Indicates the page displayed is the height above airport alert feature setup
page.
Line 3: Displays if the height above airport alert feature is ON or OFF.
Line 4: Indicates the entered value below is the height value used in this feature.
Line 5: Displays the user entered height above the airport to use when the feature is on.
To use this setup page:
1. Display the SET 5 page on the left screen and click on the LEFT CURSOR BUTTON.
2. A rectangle will appear behind the word ON or OFF, depending on the current annunciation.
3. Use the LEFT INNER KNOB to toggle between ON and OFF.
4. Click on the LEFT OUTER KNOB to go to the height entry line (Line 5). The rectangle behind
the ON/OFF annunciation will go off, and a rectangle will appear behind the 1000 place digit
of the number.
5. Use the LEFT INNER KNOB to change this number as desired. The maximum value of this
digit is 2.
6. Use the LEFT OUTER KNOB to move the active field location, and the LEFT INNER KNOB to
enter values until the desired height is entered. The last 3 digits of the height value have a
maximum value of 9, but will be inactive any time the height value reaches 2000 ft.
