[TOOL] MSFS Local Flight Planner — Open Source Preflight Planning Tool

Hey everyone,

I’ve been tinkering with this as a personal project for a while and decided to clean it up and share it with the community. It’s a local Python-based preflight planning tool I built for my own MSFS 2024 sessions — nothing professional, just something I wanted for my own flying that grew into something bigger.

What it does:

  • Route planning with destination picker and IFR alternate selection

  • Live METAR / TAF weather (FAA AWC with fallback)

  • Winds aloft with wind-corrected ETE and fuel burn adjustments

  • NOTAMs for departure and arrival airports

  • POH-based fuel planning across 52 aircraft profiles

  • Hemispherical cruise altitude selection (FAR 91.159 / 91.179)

  • SimBrief OFP integration

  • Navigraph Charts deeplinks

  • Flight plan export (.pln) with automatic MSFS Community folder copy

  • Flight logbook

Important disclaimers:

This is not a professional tool. The POH data for the aircraft profiles is incomplete and may contain errors — I compiled it from various sources and my own research, but I can’t guarantee its accuracy. Do not use this for real-world flight planning. Ever.

There are probably bugs too. It works well for my setup but I haven’t tested every scenario.

Where to get it:

https://github.com/stratomarco/msfs-flightplanner

Setup instructions are in HOWTO.md. The only thing you need is Python 3.11+ and optionally a free CheckWX API key for international weather coverage.

If anyone wants to contribute — especially correcting or completing the POH data for specific aircraft, or reporting bugs — pull requests and issues are very welcome on GitHub.

Happy flying :airplane:
