Advisory route planning
VFR-descent planner
Suggest a route that keeps a VFR-reporting airport within range at every point — ETOPS planning with a live-weather suitability predicate.
This tool suggests a route and shows margins. It never asserts that the weather will hold or that the route is authoritative. Stale or missing weather makes an airport unusable (fail-safe). Advisory / planning use only — not for navigation.
Plan a VFR-descent route
Range defaults to a 40 nm distance disk. Time-at-speed (range_min + speed_kt) and glide (glide_ratio + altitude_ft) modes are available as query parameters — see /v1/plan. Plans are capped at 600 nm great-circle — farther than that, use the trip planner.
