Flyable nationwide means that you can fly nationwide.

The route that an airplane flies is called an air traffic line, or route for short. The aircraft route not only determines the specific direction, start and end points and stopping points of the aircraft's flight, but also stipulates the width and flight height of the route according to the needs of air traffic control to maintain air traffic order and ensure flight safety.

According to the origin and destination of aircraft flights, routes can be divided into three categories: international routes, domestic routes and regional routes.

1. International routes refer to routes connecting two or more countries.

2. Domestic routes refer to routes within a country, which can be divided into three categories: trunk routes, branch routes and local routes.

3. Regional routes refer to routes connecting ordinary areas and special areas within a country, such as routes between mainland China and Hong Kong, Macao and Taiwan.

In addition, routes can also be divided into fixed routes and temporary routes. Temporary routes are usually not allowed to intersect with air routes, fixed routes or pass over airports with frequent flights.
