SELECTED ALTITUDE CAPTURE MODE (ALTS)
Selected Altitude Capture Mode is automatically armed with activation of the following modes:
• Pitch Hold
• Vertical Speed
• Indicated Airspeed
• Go Around
• Vertical Path Tracking (if the Selected Altitude is to
be captured instead of the VNV Target Altitude)
The white ‘ALTS’ annunciation indicates Selected Altitude Capture Mode is armed (see Figure 7-5 for example).
The
ALT SEL
Knob is used to set the Selected Altitude (shown above the Altimeter) until Selected Altitude
Capture Mode becomes active.
As the aircraft nears the Selected Altitude, the flight director automatically transitions to Selected Altitude
Capture Mode with Altitude Hold Mode armed (Figure 7-6). This automatic transition is indicated by the green
‘ALTS’ annunciation flashing for up to 10 seconds and the appearance of the white ‘ALT’ annunciation. The
Selected Altitude is shown as the
Altitude Reference beside the ‘ALTS’ annunciation.
At 50 feet from the Selected Altitude, the flight director automatically transitions from Selected Altitude
Capture to Altitude Hold Mode and holds the reference altitude. As Altitude Hold Mode becomes active, the
white ‘ALT’ annunciation moves to the active vertical mode field and flashes green for 10 seconds to indicate
the automatic transition.

causes the flight director to revert to Pitch Hold Mode with Selected Altitude Capture Mode armed for the
new Selected Altitude.
