Ha ! the memories of " le bel etage" so we all 3 have been through the same "thin air control " place " ?
Indeed this corner ( DIK-LNO-NOR) was and still is the most complex piece of airspace in Europe because it involves the airspace of 4 different ANSPs and the USAF ( Spangdalhem ) and it is where the departures ( and arrivals) of 5 major airports collide ( EBBR, EDDL, EDDK, EDDF and to a lesser extend LFPG ) not to mention the dozen of smaller airports around them .
Without drawing strict procedures , it would not work. Another thing is that the traffic levels today are 4 times what they used to be when the " bel etage" was in operation.. and the levels of incidents/ Airprox in there is close to nil.
So the price to pay for some "Bicycles" to stay slow and low in this area .
