Garmin G300 Pilot’s Guide 190-00921-00 Rev. EWarnings, Cautions & NotesWARNING: Navigation and terrain separation must NOT be predicatedupon the use of the terrain function. The G300 Terrain Proximity featureis NOT intended to be used as a primary reference for terrain avoidanceand does not relieve the pilot from the responsibility of being aware ofsurroundings during flight. The Terrain Proximity feature is only to be usedas an aid for terrain avoidance and is not certified for use in applicationsrequiring a certified terrain awareness system. Terrain data is obtainedfrom third party sources. Garmin is not able to independently verify theaccuracy of the terrain data.WARNING: The displayed minimum safe altitudes (MSAs) are onlyadvisory in nature and should not be relied upon as the sole source ofobstacle and terrain avoidance information. Always refer to currentaeronautical charts for appropriate minimum clearance altitudes.WARNING: The altitude calculated by G300 GPS receivers is geometricheight above Mean Sea Level and could vary significantly from thealtitude displayed by pressure altimeters. Always use pressure altitudedisplayed by the G300 PFD when determining or selecting aircraftaltitude.WARNING: Do not use outdated database information. Databases usedin the G300 system must be updated regularly in order to ensure thatthe information remains current. Pilots using any outdated database doso entirely at their own risk.WARNING: XM WX Satellite Weather should not be used for hazardousweather penetration. Weather information is approved only for weatheravoidance, not penetration.WARNING: NEXRAD weather data is to be used for long-range planningpurposes only. Due to inherent delays in data transmission and therelative age of the data, NEXRAD weather data should not be used forshort-range weather avoidance.
