GoNoGo gives you a clear FAVORABLE, MARGINAL, or NO-GO recommendation for your route — not just raw data to interpret yourself. Enter your departure, destination, and waypoints. GoNoGo pulls real-time weather from official FAA and NWS sources, analyzes the hazards, and tells you whether it's safe to fly. WHAT GONOGO CHECKS: - METARs, TAFs, PIREPs, AIRMETs, and SIGMETs from aviationweather.gov - TFRs from the FAA - NOTAMs for airport closures and navigation aid outages - NWS gridpoint forecasts for ceiling, visibility, wind, thunder, and icing out to 72 hours WHAT MAKES IT DIFFERENT: - Go/No-Go verdict — not just data, but a decision - Risk gauges for ceiling, visibility, wind, crosswind, icing, and convection - Personal minimums — set your own thresholds and GoNoGo scores against them - 72-hour travel window finder — see when conditions will be FAVORABLE across your entire route - Route watching — GoNoGo checks in the background and notifies you when conditions change BUILT FOR VFR PILOTS: - Student pilots preparing for cross-countries - Private pilots making weekend go/no-go calls - Rusty pilots who want extra confidence in their weather assessment All data comes from official government sources. No account required. No ads. No subscription. GoNoGo is a decision support tool only. It is not a substitute for official weather briefings and is not approved for operational or navigational use. See FAR 91.103.
