Audio Altitude Alert
The Audio Altitude Alert allows you to receive an audible signal when the aircraft approaches the altitude set in the autopilot. The Audio Altitude Alert is played at a distance from the set altitude. You define this distance by entering a number in the A/P Audio Altitude Alert box below. The default value for this distance is 900ft.
To illustrate how the Audio Altitude Alert works, let’s say that you are cruising at 20.000ft, and starting the descent to land. You have programmed the autopilot to an altitude of 5000ft, and the distance set in the A/P Audio Altitude Alert box is kept at the default value of 900ft. In this case, the alert will be given as you pass an altitude of 5900ft. If you are climbing from takeoff, however, and have the autopilot set to 20.000 ft, the alert will be given as you pass 19.100ft.
Note! While the other GPWS calls are voice recordings, the Audio Altitude Alert is a beep.
