• 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 barometric minimum descent altitude/decision height and bug:
1) Press the TMR/REF Softkey.
2) Turn the large FMS Knob to highlight the Minimums field.
3) Turn the small FMS Knob to select BARO. OFF is selected by default. Press the ENT Key or turn the large FMS Knob to highlight the next field.
4) Use the small FMS Knob to enter the desired altitude (from zero to 16,000 feet).
5) To remove the window, press the CLR Key or the TMR/REF Softkey.

Altitudeltitude Alerting
The Altitude Alerting function provides visual and audio alerts when approaching the Selected Altitude. Whenever the Selected Altitude is changed, Altitude Alerting is reset. Altitude Alerting is based on the altitude information shown on the PFD selected with the XFR Key on the AFCS Control Unit. Altitude Alerting is independent of the AFCS.

The following occur when approaching the Selected Altitude:
• Upon passing through 1000 feet of the Selected Altitude, the Selected Altitude Box changes to black text on a light blue background, flashes for 5 seconds, and an aural tone is generated.
• When the aircraft passes within 200 feet of the Selected Altitude, the Selected Altitude changes to light blue text on a black background and flashes for 5 seconds.
• After reaching the Selected Altitude, if the aircraft flies outside the deviation band (±200 feet of the Selected Altitude), the Selected Altitude Box changes to yellow text on a black background, flashes for 5 seconds, and an aural tone is generated.

Low Altitudeltitude Annunciationnnunciation NOTE: This annunciation is only shown if TAWS is inhibited.
When the Final Approach Fix (FAF) is the active waypoint in a GPS WAAS approach using vertical guidance, a Low Altitude Annunciation may appear if the current aircraft altitude is at least 164 feet below the prescribed altitude at the FAF. A black-on-yellow LOW ALT annunciation appears to the top right of the Altimeter, flashing for several seconds then remaining displayed until the condition is resolved.
