Lateral Separation

Minima On Diverging Radials

When using degree divergence use the following rules

Consider separation to exist between aircraft:
  •  Established on radials of the same NAVAID that diverge by at least 15 degrees when either aircraft is clear of the airspace to be protected for the other aircraft.
  • With non−VOR/DME based navigational equipment established on tracks of the same waypoint that diverge by at least 15 degrees when either aircraft is clear of the airspace to be protected for the other aircraft

Use TBL 6−5−1 and TBL 6−5−2 to determine the distance required for various divergence angles to clear the airspace to be protected. For divergence that falls between two values, use the lesser divergence value to obtain the distance

In the figure above you can see that since the planes diverged by 45 degrees there needs to be 6 NM between them to ensure separation
