AeroZulu, the conversational VFR flight brief

Field notes

The planner models Brazilian VFR routes as sequences of named visual-corridor points rather than direct airfield-to-airfield lines, including mandatory direction, altitude bands, and radio frequencies. Its displayed data inventory covers ROTAER, REA and REH segments, TMA and CTR boundaries, and restricted airspace. A sample request produces a 17-point GPX file alongside a navigation table, fuel and autonomy details, weather conditions, and a sunset-derived departure limit.
