Overspeed Protection (OSP) — The GFC 500 will provide Overspeed Protection when the autopilot is
engaged.
When the maximum airspeed of 185 KIAS is reached, visual MAXSPD message will appear above the
airspeed tape and the autopilot will raise the nose of the aircraft to avoid exceeding the maximum
configured airspeed. An aural “AIRSPEED, AIRSPEED” voice alert will sound for installations connected
to an audio panel.
Overspeed Protection is exited automatically when airspeed is reduced below 180 KIAS.
Coupled Go-Around — Pressing the GA button will not disengage the autopilot. Instead, the autopilot
will attempt to capture and track the flight director command bars. If insufficient airplane performance is
available to follow the commands, the autopilot will enter Underspeed Protection mode at the minimum
airspeed.
Electronic Stability and Protection (ESP) — The GFC 500 will provide Electronic Stability and Protection
when the autopilot is not engaged.
Electronic Stability and Protection uses the autopilot servos to assist the pilot in maintaining the airplane
in a safe flight condition within the airplane’s normal pitch, roll and airspeed envelopes.
Electronic Stability and Protection is invoked when the pilot allows the airplane to exceed one or more
conditions beyond normal flight defined below:
•
Pitch attitude beyond normal flight (+20°, -15°)
•
Roll attitude beyond normal flight (45°)
•
High airspeed beyond normal flight (above 196 KIAS)
•
Low airspeed below normal flight (below 65 KIAS)
The conditions that are required for ESP to be available are:
•
Pitch and Roll servos available
•
Autopilot not engaged
•
The GPS altitude above ground is more than 200 feet (for low airspeed mode)
•
Aircraft is within the autopilot engagement envelope (+/-50° in pitch and +/-75° in roll)
Protection for excessive Pitch, Roll, and Airspeed is provided when the limit thresholds are first exceeded,
which engages the appropriate servo in ESP mode at a nominal torque level to bring the airplane back
within the normal flight envelope. If the airplane deviates further from the normal flight envelope, the servo
torque will increase until the maximum torque level is reached in an attempt to return the airplane into the
normal flight envelope. Once the airplane returns to within the normal flight envelope, ESP will deactivate
the autopilot servos.
When the normal flight envelope thresholds have been exceeded for more than 10 seconds, ESP
Autolevel Mode is activated. Autolevel Mode engages the autopilot to bring the airplane back into straight
and level flight based on 0° roll angle and 0 FPM vertical speed. An aural “ENGAGING AUTOPILOT” alert
(or a Sonalert tone) sounds and the Flight Director mode annunciation will indicate LVL for the pitch and
roll modes.
Anytime an ESP mode is active, the pilot can interrupt ESP by using the Autopilot Disconnect (AP DISC /
TRIM INT) switch, or simply override ESP by overpowering the autopilot servos. The pilot may also
disable ESP through a G5, GI 275, or G3X menu option.
The engagement and disengagement attitude limits are displayed with double hash marks on the roll
indicator according to the airplane attitude and whether or not ESP is active in roll. When ESP is inactive
