FAA issues permanent restrictions on Washington helicopter traffic

  Of note: the 75 feet of vertical separation mentioned in the article is less than the known margin of error for altimeters used in these aircraft. Before someone asks: no, it's not possible to "just" install higher precision altimeters in every aircraft.

  Wasn’t that a military helicopter anyway? The point is, I don’t believe they care much about FAA regulations anyway.

    They are required to follow ATC instructions and obey airspace restrictions. They do this willingly because it's really, really easy to get into a midair collision of you're flying near an airport. The only exceptions are for urgent reasons of national security, or when they're flying under military ATC.
