> 200 feet vertical and 0.2nm horizontal So that's 375m (1230ft) total for anyone wondering.

  What do you mean by 375 meters "total"? They were 0.2 nautical miles apart vertically, which is 370.4 meters, and additionally they were separated horizontally by 200 feet, which is ~61 meters.

    Presumably they plugged it into the Pythagorean theorem.

  You can't really compare horizontal and vertical distances.
  • mannykannot 7y ago
    This is correct, and it is implicitly recognized in the vertical separation intervals being less than the horizontal ones. What matters even more than distance, however, is time, and in this case, fortunately, the aircraft were travelling in the same direction and so had a low closing speed (it was actually negative, I believe.)

  Planes aren't spherical and don't change directions in all ways as easily... so taking the straight line distance isn't as helpful as you'd think.
