GoNoGo: Preflight Briefing
iPhone / Météo
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
