Overspeed Protection; Underspeed Protection - Garmin G2000 Pilot's Manual

overSpeeD protection

Overspeed protection is not active in ALT, GS or GP 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 fl ight director. Pitch commands are not changed until overspeed protection
becomes active. Overspeed protection is provided in situations where the fl ight director cannot acquire and
maintain the mode reference for the selected vertical mode without exceeding the certifi ed maximum autopilot
airspeed.
When an autopilot overspeed condition occurs, the Airspeed Reference appears in a box above the Airspeed
Indicator, fl ashing 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.

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.
