BAROMETRIC MINIMUM ALERT
For altitude awareness, a barometric Minimum Descent Altitude (MDA) can be
set by the user and is reset when the power is cycled. Once the user-defined
altitude is within the range of the tape, a cyan bug appears at the reference
altitude on the Altimeter. Once the aircraft reaches the user-defined MDA/DH, the
bug and text turn yellow and the aural alert, "Minimums. Minimums", is heard.
