It also allows heavier air transport throughout the South China Coast, where the mountains often come down to the sea, with few long stretches of flat land for airstrips capable of serving this size plane outside the few river deltas. There is an historic problem of isolation on the South Coast making it a venue for “troubles” to get started, and dissidents to shelter. Lastly, much of inland China south of the Huai River, and especially South of the Yangtze, has lots of water lying around, even though many of the lakes have shrunk due to irrigation and industrial water use. This plane makes it easier to serve them with more than helicopters or small “puddle jumper” airliners.
