AUTOMATIC FLIGHT CONTROL SYSTEM
OVERSPEED PROTECTION
Overspeed protection is not active in Altitude Hold, Glideslope or Glidepath Modes.
NOTE:
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 and pitch commands are limited for overspeed protection.
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.
