are you able to give us an example airport and terminal procedure? Chinese data are limited due the restrictions of China, therefore it´s possible that Jeppesen doesn´t receive the correct data from the government of China.
Again, this is not an issue from our data, it´s more an issue from the source, means from China due the protected/restricted data offering.
The first image above is from China’s AIP and the second image is from Jeppesen. I put the right altitude in feet into the second image to explain where the problem is.
It seems that the data source provided by Jeppesen does have problems with transfer meters to feet. I really understand that a separate inspection and correction of all airport procedures in China will be a huge project, so if you can’t fix this issue, I would still appreciate your attention.
