This annunciation is not shown for systems with TAWS or Terrain SVT, unless terrain alerting is inhibited. When the Final Approach Fix (FAF) is the active waypoint in a GPS SBAS 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 left of the Altimeter, flashing for several seconds then remaining displayed until the condition is resolved. Altimeter Figure 2-51 Low Altitude on GPS SBAS Approach minimum deScent Altitude/deciSion height Alerting For altitude awareness, a Minimum Descent Altitude (MDA) or Decision Height (DH), based on barometric or temperature compensated altitude can be set. When active, the altitude setting is displayed to the bottom left of the Altimeter. Once the altitude is within the range of the tape, a bug appears at the reference altitude on the Altimeter. The following visual annunciations occur when approaching the MDA/DH: • When the aircraft altitude descends to within 2500 feet of the MDA/DH setting, the 'BARO MIN' or 'TEMP COMP' box appears with the altitude in light blue text (or magenta for TEMP COMP). The bug appears on the altitude tape in light blue (or magenta for TEMP COMP) 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 heard.
