Thanks to ALL for your constructive replies and farrell for your consideration.
The 'different rules, different cultures' statement is a cop out to be honest. China is a signatory to ICAO, and has made good use of International best practice systems such as RVSM, however applying it to it's archaic airspace system is 'papering over the crack', or a quick fix if you like.
China has some of the most modern airports in the world that it should be rightly proud of, but is let down by the airspace mangement (slot times and sequence for departure, airways routes that are too congested in limited airspace causing the "decend 3,00 feet per minute" when 200NM from the destination), or closing airports when some storms around too prematurely. You can have 3 runways, but it does not increase the traffic flow for China right?
This also does not fix the 'delay not determined' situation. You need a SLOT system for ARRIVAL and DEPARTURE that is fair and honest. ALL carriers, Chinese and Foriegn get it at other countries airports, so the different rules , different cultures is being disrespectful and just plain wrong. This creats a bad impression for China, and one that a proud, emerging country should correct.
We know that the 'restriction' is caused by military, but they need to face up to what is best for China. The UK also has very busy airports, such as the London area (Heathrow, Luton, Stanstead), with very busy military flying, but there is NO big impediments as caused by the China 'differnet culture, different system' way.
Time to accept there is a problem and address it?
