This application is intended to confirm and verify the flight route of aircraft in Japan. Complete the air route by forming a connection in four steps from the departure to the arrival of the aircraft. The flight route is based on the Aeronautical Information Publication (AIP) published by the Ministry of Land, Infrastructure, Transport and Tourism. ■ Route creation Create a route from the departure airport to the arrival airport using the stored flight routes (DEPARTURE, ENROUTE, ARRIVAL, APPROACH). ■ Full display of ENROUTE Shows all routes for RNAV, LOWER ATS ROUTES, OTHER ROUTES, OCEANIC TRANSITION ROUTES. ■ Detailed route display Displays individual routes for DEPARTURE, ENROUTE, ARRIVAL, and APPROACH. ■ Waypoint display Displays a list of waypoints that make up ENROUTE and location information. ■ Flight log When you actually fly, you can record the flight route using the location information. It is possible to confirm and verify the flight route from the recorded information at a later date. Please follow the airline's instructions when using location information on board. Also, since the use of location information consumes a lot of battery power, please turn on / off the location information at sufficient intervals (example: 5 minutes or more) when recording. ■ Target airports Routes can be created between the following airports.
