A good go/no-go call weighs weather, NOTAMs, runway performance, and fuel all at once. FlightDecide pulls them into one briefing and gives you a clear GO, CAUTION, or NO GO to review before you leave the ground. Build your flight and get an AI-assisted preflight briefing that gathers the scattered pieces in one place: • Path to GO: for CAUTION and NO GO flights, the exact changes that would flip the call • Free pilot tools: a built-in E6B suite (crosswind, density altitude, true airspeed, weight and balance, and more) that works offline and stays free on every plan • Aviation weather: METARs, TAFs, winds aloft, SIGMETs, G-AIRMETs, and PIREPs • NOTAM awareness for departure and destination • Weight and balance with a CG envelope check and specific load fixes • Takeoff and landing performance against actual runway lengths • Fuel planning with legal reserves and your personal minimum fuel • Cruise altitude: every altitude scored for winds, icing, and turbulence Every flight is scored across 8 risk categories, from weather and NOTAMs to performance, fuel, and weight and balance, then summarized as one GO, CAUTION, or NO GO. Set your personal minimums for ceiling, visibility, wind, and fuel, and your limits go into every analysis. Instead of jumping between a weather app, a NOTAM lookup, a performance chart, and a fuel calculator, you check one briefing. Export any analysis as a PDF for your records. FlightDecide is an advisory tool only and doesn't replace official weather briefings, approved aircraft data, or pilot in command judgment. Always verify critical information with official sources before flight. Privacy Policy: https://flightdecide.com/privacy.html Terms of Use (EULA): https://flightdecide.com/terms.html

  • This app hasn’t received enough ratings or reviews to display an overview.

This release is mostly about the app telling you the truth about what it knows. The app no longer tells you an airport publishes no METAR or TAF when the real story is that the fetch failed. That claim used to appear on the same branch as a network error, so a station with a perfectly good report could read as a station that files nothing. The model-forecast badge made the same mistake in two cases where a TAF exists. Both are fixed, the briefing's weather summary now distinguishes "we asked and the call failed" from "this station publishes nothing", and a brief provider error is retried before anything gets declared missing. Weight and balance uses your aircraft's real CG envelope. The app used to keep only two corner points, so a tapered envelope became a rectangle. The full certified envelope now travels end to end, the table on the aircraft placard comes from the library rather than from a guess, and a caption tells you when a limit between two published points was interpolated. Personal minimums are checked, not assumed. The banner, the PAVE pilot chip and the summary line all read the same ledger. The green "within your minimums" line appears only when every enforced limit was measured and cleared. A breach names the limit it broke, and a ceiling or visibility we couldn't measure says so instead of showing green. Significant weather buried in the remarks section is now read. Funnel clouds, smoke, dust and pressure changes reported only in remarks get a signal on the card, and a tornado that has ended no longer looks like one in progress. The exported briefing record says what it is. Every export carries the time it was made in labelled UTC, the build that produced it, and a line stating it isn't an official weather briefing. Filenames start with the analysis time so records sort in order, exports include the NOTAMs they say they retrieved, and a runway closure is no longer filed under performance estimates. Accessibility: the "Analysis Failed" card shows its whole message at large text sizes, and the analysis progress rows tell VoiceOver which stage they're in rather than just their name. Also fixed: an edge-proxy error no longer shows raw proxy text as the failure reason, and airspace data holds up when the FAA rate limits us.
