The Altitude Reference Bug is displayed at the Selected Altitude or the edge of the tape (whichever is closer to the current altitude) to provide increased altitude awareness and to set the desired hold altitude for the autopilot.
Set the Altitude Reference Bug:
Turn the ALT Knobs to set theAltitude Reference Bug. The small ALT Knob sets the hundreds and the large ALT Knob sets the thousands. This altitude also appears in the Altitude Reference Box above the Altimeter.
Altitude Trend Vector
The end of the trend vector displays approximately what the altitude will be in six seconds if the current rate of vertical speed is maintained.
Barometric Setting Box
Select barometric pressure:
1)Turn the BARO Knob to select the desired setting.
2)Push the BARO Knob to select standard pressure 29.92.
