Why can’t my planes cross certain wastelands?

Aircraft must always have a Landing Pad within their flight range. If no reachable Landing Pad is available at the destination, the flight cannot be ordered.

To move planes across wastelands or between islands, you must capture or build Landing Pads within range to create a valid flight path.

Leveling up aircraft units increases their flight range, allowing them to cover greater distances.

Aircraft cannot convert to trucks or land on unoccupied ground.
