OK. You will have the possibility to change some parameters, to add some software lines around the core, but no access to the core.Türkiye has been granted the authority to interfere with the mission computer and have full control over the operational software. Turkish engineers will be able to modify the Eurofighter's avionics software according to national needs and integrate domestic weapons/data link systems.
As windows : you can add some add on, change a lot of parameters, but can't modify the core of the soft.
