SyStem overvieW Flight inStrumentS AutomAtic Flight control SyStem overSpeeD protection note: Overspeed protection is not active in ALT, GS or GP 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. eiS AuDio pAnel & cnS Flight mAnAgement AvoiDAnce hAZArD AFcS ADDitionAl FeAtureS Airspeed Indicator Figure 7-41 Overspeed Annunciation unDerSpeeD protection Underspeed Protection is designed to discourage aircraft operation below minimum established airspeeds and is available when the autopilot is on. When the aircraft reaches a predetermined airspeed (Table 7-6), a yellow MINSPD annunciation (Figure 7-42) will appear above the airspeed indicator. When the airspeed trend vector reaches a predetermined airspeed (Table 7-6), a single aural "AIRSPEED" will sound, alerting the pilot to the impending underspeed condition.
