The government is requiring that pilots are qualified to use the low-visibility landing system by the beginning of next year. Many pilots are already using the system with visibility at 800 meters, but now they will need to be able to use it when visibility is just 400 meters. About 80 percent of Chinese pilots already have the necessary training, but that won't be the main challenge, according to China Daily:
A senior pilot at China Southern said on condition of anonymity that it is not difficult for pilots to pass instrument-landing system tests. "The biggest concern for airlines and airports would be the cost of refitting their aircraft and airport facilities," he said.
Despite all the challenges China's airlines face, the country is set to be one of the most important aviation markets in the coming years. The latest projections show that 24 percent of all new passenger growth will come from flights within or connected to China, making China the biggest driver of new passenger growth in the world, serving 227 million additional passengers.
That is, if the smog doesn't drive them away first.
