Adjustments to radial intercepts
Sg 4, fr 13
1.
Inbound radial intercepts require a greater
lead than outbound because the aircraft is
turning more than 90 degrees
2.
For radial intercepts from arcs less than
approximately 10 DME, an adjustment must
be applied to the arc to radial formula to
compensate for turns outbound of less than

INTERCEPTS
90 degrees and turns inbound of more than
90 degrees
a.
Degrees to turn outbound are equal to
90 minus the number of lead radials
determined by formula
b.
Degrees to turn inbound are equal to
90 plus the number of lead radials
determined by formula
c.
As a rule of thumb, reduce or increase
the lead radials determined by formula
by one-third
3.
Some SIDs have the lead radial or lead
DME published
a.
Published lead radials are not all
determined by the same formula and
may require modification when flown at
1/2 SRT
b.
Published lead DMEs must be adhered
to; therefore, and adjustment in speed
and/or angle of bank may be required
to intercept the published arc
