שים לב לקטעים\איורים הבאים:
ציטוט:
The block 50 F-16 Terrain-Referenced Navigation System provides a "position" input to help a new algorithm decide what nearby terrain could present a hazard to the aircraft. Based on the fighter's maneuvering attitude at any given moment, a specific area of the terrain database is "scanned," and elevation information is compressed into a 2D model.

Ultimately, the computer determines how much time is available before the aircraft will break through a pilot-selected minimum descent altitude (MDA), then triggers an autopilot- commanded protective maneuver. Typically, two chevrons (><) appear in the head-up display 5 sec. prior to an automatic fly-up, warning the pilot that Auto-GCAS is about to take over. If he takes no action, the chevrons move toward each other until their points meet, a flashing "break-X" symbol appears in the HUD and an aural warning annunciates, "Fly-up! Fly-up!"
At that instant, the Auto-GCAS commands some of the most aggressive, eye-watering maneuvers this ex-USAF flight test engineer and civil pilot has ever experienced.

If aircraft speed is insufficient to climb adequately during a pull-up, the system also will announce, "Power! Power!", urging the pilot to push the throttle forward and gain airspeed.

ואם כבר דיברת על נחיתה, ניתן להבין שכאשר כני הנסע מורדים המערכת משהה את עצמה.
ציטוט:
For our flight, Prosser set the Auto-GCAS in "Active" or "Low-Level" modes, with "Standby" appearing on the HUD only when the landing gear handle was moved to the gear-down position.
.
.
On final approach for landing at Edwards, the Auto-GCAS switched to "Standby" as soon as the gear handle was lowered. If we had made a touch-and-go, the system would have automatically reactivated at gear-up. For safety reasons, it also is automatically deactivated when the air refueling door is opened, or alternate flaps are selected.
