pointer while the other end moves continuously up or down according to the rate of vertical speed. For any
constant rate of vertical speed, the moving end of the line shows approximately what the indicated altitude
value will be in six seconds. The trend vector is absent if the altitude remains constant or if data needed for
calculation is not available due to a system failure.
Setting the Selected Altitude:
Turn the ALT SEL Knob to set the Selected Altitude in 100-ft increments (if baro-min reference is set, the selected
altitude can be set in 10 foot increments to match the baro-min value).
If set, the Minimum Descent Altitude/Decision Height (MDA/DH) value is also available for the Selected Altitude.
