The solution? RNP.
A few days ago heard a great conversation between spanish atc & the crew of a national airline based in the next country, slightly to the west.
Said crew asked for direct to some VOR only to be refused & instructed to follow flight plan route. Crew then asked to fly 3nm "offset right" due to safety. ATC refused only for crew to ask again followed by another very blunt refusal! Crew then asked to confirm the airway was certified RNP 10. imagine the confusion at this question, it took a while for the penny to drop, but eventually it was confirmed as RNP 10 &you can guess what happened next, they announced & turned for the 3nm Offset Right!! I can only imagine 3nm put them on a direct track to the previouse requested VOR!! ATC was speachless & I assume powerless. If we all did this then the spanish bullsh*t would soon stop. Unfortunately I didnt have the balls to follow the example. Pity really.
