MINIMUM DESCENT ALTITUDE/DECISION HEIGHT ALERTING
For altitude awareness, a barometric Minimum Descent Altitude (MDA) or Decision Height (DH), based on
barometric altitude can be set. When active, the altitude setting is displayed to the lower left of the Altimeter
and with a bug at the corresponding altitude along the Altimeter (once the altitude is within the range of the
tape).
The following visual annunciations alert the pilot when approaching the MDA or DH:
• When the aircraft altitude descends to within 2500 feet of the MDA/DH setting, the ‘BARO MIN’ box appears
with the altitude in light blue text. The bug appears on the altitude tape in light blue once in range.
• When the aircraft passes through 100 feet of the MDA/DH, the bug and text turn white.
• Once the aircraft reaches the MDA/DH, the bug and text turn yellow and the aural alert, “Minimums
Minimums”, is generated.
Alerting is inhibited while the aircraft is on the ground and until the aircraft reaches 150 feet above the setting
for the alert. If the aircraft proceeds to climb after having reached the MDA/DH, once it reaches 50 feet above
the MDA/DH, alerting is disabled.

The MDA/DH may be set from either PFD and is synchronized on both PFDs. The function is reset when the
power is cycled.
Setting the Minimums Descent Altitude/Decision Height:
1)
Press the
TMR/REF
Softkey.
2)
Turn the large

3)
Turn the small
FMS
Knob to select BARO. OFF is selected by default. Press the
