Greek ATC: they would ask you your DME from a station that you had no desire to route to or from, and so had to dig out the chart, and tune your one DME to it, and then try to get the answer back to them....they were the butt of all english atc jokes.
It was not really the controller's fault that they had no radar, just another sad story about Greek reality and politics............
Given the traffic levels, the fact that not even the frequencies worked properly, and that they applied procedural en-route control until approximately 1995 it is a miracle that no serious accident happend.
In general it is not so much the controller's fault but that of the Greek CAA and the politicians.
If you ever wondered why you have to ident or confirm your squawk when transferred eg to Heraklion APP it is because the appoach radar and computer system is not compatible with the ACC system in Athens..... you can perhaps imagine how the decision to buy non-compatible systems was taken............
Also controllers have a hard time obtaining new and more reasonable STARs and SIDs from the CAA in Athens.... sometimes they have to wait and insist for years........
Now I find them very very efficient., I think the Watchman radar was the solution ... Comments.???
Some approach radars for the smaller busy charter airports would be nice though.........
It seems that they will at least get a radar image from the en-route radars this year......
