- RNAV (Area Navigation)A method of navigation that allows aircraft to fly on any desired flight path within the coverage of referenced navigation signals or within the limits of self-contained system capability (GPS). RNAV approaches are the most common GPS-based instrument approaches.
- Sectional ChartAn aeronautical chart used for VFR navigation that depicts topographic features, airspace boundaries, airports, navigation aids, and other information at a scale of 1:500,000. Sectional charts are updated every 56 days.
- SIGMET (Significant Meteorological Information)An in-flight weather advisory for significant hazards that may affect all aircraft, such as severe icing, severe or extreme turbulence, dust storms, or volcanic ash. SIGMETs are checked with convective SIGMETs and G-AIRMETs when building a route weather picture.
