What is the exit limit of C919? Also, what is the maximum seating capacity in a single-class configuration? Considering that its 1 meter longer than the A320, it should be able to carry more than 186 passengers.

This picture is basically accurate, but three things. First notice that the radar and entire airframe are domestic. Western pundits will tell you that making the airframe of a big civilian jet from scratch is some easy feat. It isnt. Second, see that the only foreign made technology which China cannot currently produce is the civilian high bypass turbofan. Third, notice that many of the supposedly foreign-made things, particularly the avionics, are actually made in China by JVs.

COMAC absolutely could have had every subsystem save the engine be domestic, but it deliberately chose foreign suppliers in order to speed up airworthiness certification in foreign markets. And of those foreign suppliers, many are actually in China and produce with a substantial degree of localization.

Not just avionics which are already made in China via SAIFEI i.e. JV with COMAC, even the components for the LEAP engine and other CFM engines are made at Safran's plants in China e.g. Suzhou, Guiyang etc. then shipped to their Villaroche plant in France which is basically an assembly plant just so the engine can be called Western-made.

The Chinese view on these things is that you first bring them in on JVs and then over time you learn how these things work and what are needed to satisfy customer requirements and then you are able to replace them.

Longer term, most of these items have some version of domestic suppliers, since China has large transports that need a lot of the similar subsystems. As your domestic subsystems make investments for C919 & other civil aerospace programs, that cost can be spread out to your military programs and lower costs all the way around. That's why Chinese shipbuilding is so efficient. Can you imagine the cost issues that American military aerospace programs will run into if Boeing has to exit civil aerospace? That would devastate major Boeing suppliers like Spirit Aerosystems and just certain scale cost advantages that American military aviation programs still have.

Think a lot about this. C919 will bring in a lot of Chinese suppliers that will replace certain Western ones. COMAC has a very important role in cultivating domestic supply chain.

There are two reasons to have foreign suppliers for multiple components.

1. Speed of production. It would have taken many more years for the C919 to come to market if every component was designed domestically. It may (probably will) become necessary in the future, but while China has a very strong trade balance there's not much they can do.
2. Capture of the international market. Having American, French, and other partners makes it easier to export to the respective companies. There's a lot of politics in exports and companies manufacturing components for the C919 will be 100% lobbying their governments to certify C919.
