Altitude Alerter
The function of the Altitude Alerter is
independent of the autopilot.
1. ALTITUDE SELECT knob -
ROTATE until the selected altitude
is displayed.
Note: The ALERT annunciation is
illuminated 1000 ft. prior to the
selected altitude, extinguishes 200 ft.
prior to the selected altitude and illu-
minates momentarily when the
selected altitude is reached. Once
the selected altitude is reached, a
flashing ALERT illumination signifies
that the 200 ft. “safe band” has been
exceeded and will remain illumi-
nated until 1000 ft. from the selected
altitude. Associated with the visual
alerting is an aural alert (five short
tones) which occurs 1000 ft. from
the selected altitude upon approach-
ing the altitude and 200 ft. from the
selected altitude on leaving the alti-
tude.
Altitude Alerting and Preselect
The Altitude Preselect function allows capturing of a selected altitude and
transferring into altitude hold. Manual input of selected altitude is accom-
plished through the rotary knobs on the faceplate of the KFC 225.
The Altitude Alerting function will visually and aurally announce approaching,
acquiring and deviation from a selected altitude.
