Plan a leg

Two idents. The distance, the track to steer as you leave, the cruise levels the semicircular rule offers, and roughly how long it takes in the sort of aircraft people fly here. No winds, because there is no wind model behind this and pretending otherwise would be worse than saying so. If you would rather be told where to go, say so below and it will pick something.

Find me a route

Answer as much or as little as you like. It will not offer you a leg the aeroplane cannot make, a runway it cannot get into, or a destination the airline has never flown to.

The solid line is the route. The faint one is the straight line on this projection, which is longer to fly and is what people expect the route to be.

Roughly how long

Still air, plus half an hour for the climb, the descent and the taxi at both ends. A real day is longer or shorter by whatever the wind is doing.

  • Narrow body450 kt35 min
  • Wide body490 kt35 min

Both ends

Halfway is 39.8°N 89.3°W, which on a long leg is further north than the map makes it look.
