GoNoGo: Preflight Briefing

GoNoGo: Preflight Briefing is a pilot-focused navigation and weather app that helps you make confident go or no-go decisions in minutes. It consolidates route-based aviation weather, NOTAMs, and TFRs into a clear, color-coded briefing tailored to your aircraft and personal minimums. Plan VFR or IFR flights, visualize hazards on an interactive map, and generate a shareable briefing package for safer, faster preflight planning. Core features include route-centric weather with METAR, TAF, radar, satellite, winds aloft, icing and turbulence layers; smart risk cues with personal minimums and departure time sensitivity; and interactive maps that track conditions along your planned altitude and waypoints. Ideal for cross-country planning and everyday operations, this aviation weather app streamlines preflight, boosts situational awareness, and complements your EFB workflow.

1. Download and create your pilot profile, then add aircraft details, preferred units, and personal minimums. 2. Sign in and start a new plan by entering departure, destination, ETD, planned altitude, and optional alternates or waypoints. 3. Generate your briefing to view METARs, TAFs, NOTAMs, TFRs, radar, satellite, winds aloft, icing, and turbulence along your route in a color-coded summary. 4. Review the interactive map, toggle weather layers, adjust time or altitude, and see how changes affect risk and your go or no-go decision. 5. Save or export a briefing package, set alerts for significant changes, and cache data for offline use before heading to the airport.
