GAMETGAMET area forecast. An area forecast in abbreviated plain language for low-level flights for a flight information region or | |
GBASGBAS landing system (GLS) means an approach landing system using ground based augmented global navigation satellite system (GNSS/GBAS) information to provide guidance to the aircraft based on its lateral and vertical GNSS position. It uses geometric altitude reference for its final approach slope. | |
Geodesic distanceGeodesic distance. The shortest distance between any two points on a mathematically defined ellipsoidal surface. | |
Geodetic datumGeodetic datum. A minimum set of parameters required to define location and orientation of the local reference system with | |
GeoidGeoid. The equipotential surface in the gravity field of the Earth which coincides with the undisturbed mean sea level (MSL) | |
Geoid undulationGeoid undulation. The distance of the geoid above (positive) or below (negative) the mathematical reference ellipsoid. | |
Glide path.Glide path. A descent profile determined for vertical guidance during a final approach. | |
GliderA non-power-driven heavier-than-air aircraft, deriving its lift in flight chiefly from aerodynamic reactions on surfaces | |
Glider flight timeThe total time occupied in flight, whether being towed or not, from the moment the glider first moves for the | |
