Plan a VFR cross-country: waypoints from airport codes, coordinates or a tap on the map; great-circle course and distance; magnetic variation from the World Magnetic Model; winds aloft per leg (typed or the US forecast from aviationweather.gov); wind correction angle, true and magnetic heading, ground speed, time and fuel per leg with climb, descent, taxi and reserve; checkpoints; and a printable kneeboard nav log.
Tool ·
Great-circle distance, initial and final course, and midpoint between airports; multi-leg routes drawn on a map across the date line; a flight-time estimate by aircraft type; a per-passenger CO₂ estimate; and an airport lookup with runways and elevation.
Tool ·
Live aircraft near you or any airport — on a map or an offline radar scope, in a sortable table, and as an "overhead now" list — from public ADS-B feeds or your own receiver's aircraft.json, with trails, altitude colours, emergency-squawk alerts and a watchlist.
Tool ·
"What's that plane?" — point your phone at the sky and see the aircraft labelled where they are, with callsign, type, altitude and distance, using your location, the phone's compass and tilt, and optionally the camera; a sky plot and a list work everywhere else.
