Talk:Separation (aeronautics)

I've deleted the merged-in conflict section. It looked like it was written from a hypothetical engineering perspective rather than an ATC perspective ('temporal altitude'... 'flight units'...), and therefore has no real place here. The narrative about assistants roles and controllers roles was not globalized (to be honest, I think it was either badly translated into English from another language, or was at least 40 yearsout of date, probably both).BaseTurnComplete (talk) 22:38, 13 December 2007 (UTC)

Flight units
What is a "flight unit"? I can't seem to find a definition (even checked Wikipedia!). In the article, "flight unit" refers to some kind of a unit of distance. I think the article would be more useful if this term were defined, perhaps with a link. — Preceding unsigned comment added by PurpleLobsterNinja (talk • contribs) 22:37, 2 June 2011 (UTC)

Order of magnitude for horizontal separation
On this page, about procedural separation, it is said that the “golden rule“ for horizontal separation of two planes following the same route is a distance in time of 15 minutes. Now for airliners flying at 800 km/h (which is slow), that means a safety distance of 200 km.

But then, there is also the radar separation, for which a common legal value is 5 nautic miles of horizontal distance, that is, 9.3 km. That’s vastly inferior!

What is my misunderstanding here? Does the first rule supersedes the second one for tail-to-head distance (then the second rule would only apply to lateral distance)?
