I don't know how it is in the USA, but in this part of the world, a taxi
instruction does *not* imply the right to cross a runway.


Why not? What's the point of an instruction to do something if it cannot be
done without additional instructions? In the US, a clearance to "taxi to"
any point other than an assigned takeoff runway is clearance to cross all
runways that intersect the taxi route to that point, as one would logically
expect.



No, as I pointed out.


I missed where you pointed that out. In the US, controllers are held
responsible for their actions. Not so in Germany?



But anyway, this isn't the question. Good security management is
designed to be redundant. Being on the right frequency is
just one of several security layers.


Good ATC is designed to not have two or more aircraft authorized to be in
the same place at the same time.



That's right. The airport chart is on page 17.


I don't read German.
