2.4.4 Minimum Descent Altitude/Decision Height
Alerting
For altitude awareness, a Barometric Minimum Descent Altitude (MDA) or
Decision Height (DH) alert can be displayed on the PFD. The values are set in
the Active Flight Plan page. When active, the minimum descent altitude setting
is displayed in the minimums window at the bottom left of the Altitude Tape
when you are within 2500 feet of the selected minimum altitude.
NOTE:
The Altitude Minimums Alerting Bug appears parked at the bottom
of the altitude tape as soon as a value is set in the minimums alerter. The
bug will unpark and start to move up the tape as soon as the altitude is
within the range of the tape. The bug is reset when power is cycled.
The following visual annunciations occur when approaching the MDA/DH:
•When the aircraft altitude descends to within 2500 feet ofthe selected
altitude setting, the BARO MIN box appears with the altitude value in cyan
text.
