          than 15 degrees.

REF FIG 6-2-5

Preceding A/C has passed the point of runway intersection and the runways diverge by 30 degrees or more,

or runways diverge by 15 to 29 degrees inclusive and the preceding A/C has commenced a turn.

3 minutes until the following A/C passes through the assigned altitude of the leading A/C;

or 5 miles between DME equipped A/C; RNAV equipped A/C using ATD; and between DME and ATD A/C provided the DME A/C is either  10000ft or below or outisde of 10 miles from the DME NAVAID.

REF FIG 6-2-8 & 6-2-9

What are the 4 ways to separate A/C longitudinally?

following.

2. The A/C are separated by not more than 4,000ft when the altitude change started.

3.  The change is started within 10 minutes after a following A/C reports over a fix reported over by the leading A/C or has acknowledged a clearance specifying the time to cross the same fix.

REF 6-4-3 

1.  Clear A/C on different airways or routes whose widths or protected airspace do not overlap.

2.  Clear A/C below 18,000ft to proceed to and report over or hold at different geographical locations determined visually or by reference to NAVAIDs.

3.  Clear A/C to hold over different fixes whose holding pattern airspace areas do not overlap each other or other airspace to be protected.

4.  Clear departing A/C to fly specified headings which diverge by at least 45 degrees.
