With GPS (Global Positioning Systems) now standard equipment in virtually all aircraft, GPS mastery is becoming as necessary to pilots as basic stick and rudder skills. With a unique set of six field-test flight lessons, this guide teaches pilots how to use GPS equipment in all common VFR (Visual Flight Rules) and IFR (Instrument Flight Rules) flight situations, in last-minute changes, as well as in emergencies.* Fully illustrated throughout with charts, maps, photos, and diagrams.
