## What is GoNoGo?

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
