The certificate is self issued by DJI the Chinese manufacturer of the drone...it does not give you permission to break Thai CAAT law.
Thai immigration warned me about flying in my land 6 kms west of Hua Hin saying it was illegal.
I will end as I began Hua Hin City is a no fly zone according to immigration and CAAT laws.
You carry on believing you are ok but by self unlocking you are stating you have permission to fly....you do not.
I was hoping you had a legal way to get permission to be able to fly within 9kms of the airport.
Not trying to be argumentative but do not want a big fine. Self unlocking will certificate you to fly above Hospitals, schools, Army camps, National Parks, and even The Grand Palace in Bangkok but will not give you permission!
