OVERSPEED PROTECTION
NOTE:
Overspeed protection is not active in Altitude Hold, Glideslope or Glidepath modes.
While Pitch Hold, Vertical Speed, Flight Level Change, Vertical Path Tracking, or an altitude capture mode is
active, airspeed is monitored by the flight director. Pitch commands are not changed until overspeed protection
becomes active. Overspeed protection is provided in situations where the flight director cannot acquire and
maintain the mode reference for the selected vertical mode without exceeding the certified maximum autopilot
airspeed.
When an autopilot overspeed condition occurs, the Airspeed Reference appears in a box above the Airspeed
Indicator, flashing a yellow ‘MAXSPD’ annunciation. Engine power should be reduced and/or the pitch reference
adjusted to slow the aircraft. The annunciation disappears when the overspeed condition is resolved.
