This application uses the A* pathfinding algorithm to find the best route of waypoints to follow for your flight.
Select a start waypoint and a goal waypoint from the dropdown menus, then click "Find Path" to find the best route.
EzyDubbs has made a really good enroute waypoint chart which you can use here.
At this point, there is no implementation for SIDS and STARS. This may be a feature available in the future, but the wide arrange of charts available makes it a lot harder to add.
This route planner was made by Efteman1.
