Since 000 is not a real direction... (North is 360) ..., is there some
significant history why easterly/westerly cruising altitudes were
chosen on


Of course it is a real direction - its the same direction as 360. Its
merely a piece of terminology that is no longer in use for one reason or
another.


Zero is no longer in use for north? Is it not the marine standard for
north?
