b. Should the aircraft deviate 100’ or more from your
selected altitude, the ‘
ALT’ annunciator will illuminate.
Refer to your primary altimeter to determine if you are
high or low and correct to the proper altitude. Correcting
the aircraft’s altitude will extinguish the ‘
ALT’
annunciator.
c. If the aircraft deviates 200 feet or more, the ‘
ALT’
annunciator will flash at a rate of approximately twice per
second. Again, refer to the aircraft’s primary altimeter and
correct to the proper altitude.
d. If you change altitudes or barometric setting in your
altimeter and readjust your aircraft’s altitude, the AIM
function will need to be reset. To reset the AIM, simply
press the pushbutton once. This will turn the AIM
function off. Then press it a second time to ‘
SET’ the new
altitude.
e. To turn off the AIM function, simply press the ‘
SET’
pushbutton a second time. The ‘
SET’ annunciator will
extinguish.
