Need info on aircraft separation

[Al B]

According to FAA regulations, is there any restriction on the
horizontal separation of aircraft?

I was unable to find anything in the FAA regs:

http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgFAR.nsf/MainFrame?OpenFrameSet

Part 91, Section 111 ("Operating near other aircraft") doesn't seem to
answer this. Part 91, Sections 159 and 179 deal with the vertical
flight deck concept based on compass direction, but doesn't indicate
any required horizontal separation.

The real question I'm trying to get an answer to has to do with
whether there is any required horizontal separation of passenger jets
that are flying at different flight decks.

If anyone knows the answer to this, I would really appreciate your
answer. Thanks!

If adequate vertical separation exists, no lateral separation is
required.
Vertical separation between airliners flying under instrument flight
rules (IFR) is normally 1,000'. The vertical separation of IFR
jetliners and general aviation aircraft flying under visual flight
rules (VFR) is normally 500'.
There is NO separation required for two VFR aircraft except to not
cause a collision hazard.

Above FL290 vertical sep is 2,000', at least until domestic RVSM is
implemented. But, just as a slight correction, it's not just between
airliners. It's between any traffic (air carrier/gen av/military).

If you're asking if there is any regulatory separation minima placed upon a
pilot, the answer is no. Separation minima is established for controllers
and it varies with the Class of airspace and the type of operation; IFR,
VFR, or SVFR.

Vertical separation between aircraft flying under IFR is 1000' at and below
FL 290, 2000' above FL 290. It doesn't matter if they're airliners or not.

IFR/VFR vertical separation is 500' in Class B and Class C airspace, it
doesn't matter if they're jetliners or general aviation. There is no
IFR/VFR separation in Class D or Class E airspace.

VFR/VFR separation is required in Class B airspace.

Yes Steven, I took into consideration the knowledge level of the
person requesting the information.
