This form allows you to determine the distance between any two airports in our database that have coordinates. It can produce a map of the flight route and returns a link to enroute weather information. Just enter the airport identifiers in the two fields below. If you specify your airspeed, it will also calculate flight times. The map will include airports that are close to the route in fairly evenly spaced segments. If you specify the endurance (time that the airplane can fly with a load of fuel) in addition to airspeed the system with calculate the enroute airports so that you can reach every airport within the endurance time (no allowance for fuel reserve or headwinds is made). You can select to have only airports along the route that have METAR and/or TAF information available. Clicking on an enroute airport will return the information for that airport along with links to various information like weather, local maps, NOTAMS, etc.

The input fields are case insensitive, so you can enter upper or lower case letters.

If any of the identifiers is ambiguous, append country, separated by a comma. Enroute aiports need to be separated by semicolons. If you want to use a VOR or NDB as an enroute waypoint, append "-vor" or "-ndb" to the identifier (eg gdm-vor for the Gardner, MA VOR instead of GDM for Gardner, MA airport, ore-ndb for the Orange, MA NDB instead of the Orange, MA airport). You can also specify coordinates for a waypoint. They need to be specified as lat,long, where lat and long are the latitude and longitude in decimal degrees, with west longitude and south latitude being negative, and lat and long separated by a comma, no spaces.
