Foreword Sec 1 System Sec 2 PFD Sec 3 MFD Sec 4 Hazard Avoidance Features 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 of the selected altitude setting, the BARO MIN box appears with the altitude value in cyan text. • When the aircraft is within 100 feet of the selected altitude setting, the bug and text turn white. • Once the aircraft reaches the selected altitude minimums setting, the bug and the altitude text turn yellow and the aural alert "Minimums, minimums," is heard one time. The text remains in yellow until the aircraft altitude is more than 50 feet above the set altitude minimum value.
