SIGMET Plotter 1.9 brings major improvements to route plotting and navigation data. * Expanded navigation database with additional VOR, VORTAC, DME, TACAN, NDB, and waypoint/fix data across the United States. * Improved recognition of navigation identifiers when entering a flight route. * Enhanced route plotting using sequential navigation points. * Better handling of fixes and radio navigation aids for more accurate route visualization. * General improvements to reliability and navigation data processing. These updates make it easier to plot your route and visualize its relationship to SIGMETs, NOTAMs, weather hazards, and affected airspace directly on the map.

Route display enhancement. Improved dark and light schemes

Minor bug fixes. Improved stability.

• Added offline map support for reliable route and SIGMET visualization without internet connection • Fixed waypoint issues that could cause route duplication or incorrect segments • Improved route plotting accuracy and stability

• European Free Route Airspace (FRA) waypoint support added. • Expanded internal waypoint database (Europe, United States, and Canada). • Improved FMC LEGS, oceanic ARINC 424, and PBCS/NAT route parsing. • Performance and stability improvements.

Added support for FMC LEGS input — paste fix names directly and visualize routes instantly. • New Oceanic ARINC 424 reporting points support (e.g. 5040N, 75N70). • Integrated PBCS / NAT half-degree points (e.g. H5320). • Automatic format detection — no manual mode selection required. • Improved waypoint resolution using an internal FAA-based database. • Enhanced route plotting stability and validation logic. • General performance and reliability improvements.

• Clearer map plotting for SIGMET areas and routes • Improved text and image input from briefing PDFs and ACARS messages • Minor UI refinements for faster flight route displays • Stability and performance improvements

Route plotting added. Coordinate extraction improved for greater accuracy and stability.
