RADIAL TO ARC INTERCEPT ADJUSTMENTS
2.
Radial to arc intercept adjustments
a.
When intercepting an arc from a heading significantly more or less
than 90 degrees from the arc, an adjustment should be made to the
result of the formula for arc intercepts
(1) Use 1% for a turn of approximately 90 degrees
(2) For a turn of approximately 45 degrees, use 1/3 of that required
for 90 degrees
(3) For a turn of approximately 60 degrees, use 2/3 of that required
for 90 degrees
(4) For turns of less than 30 degrees, very little lead is required
b.
When intercepting an arc from a radial closer than approximately
12 DME, an adjustment should be made to compensate for outbound
turns greater than, and inbound turns less than 90 degrees
(a) Outbound radial to arc, add approximately 1/2 DME to 1%
ground speed
(b) Inbound radial to arc, subtract approximately 1/2 DME to 1%
ground speed
