D.
Intercepting a radial from an arc lead point
Sg 4, fr 6
calculation
60
------------ X 1% GS = NUMBER OF LEAD RADIALS
ARC DME
(USING 1/2 SRT)
1.
Estimate the ground speed
Vary AOB to intercept desired
inbound/outbound radial
2.
Apply the following formula to determine
ARC TO RADIAL LEAD POINT
lead radials: "60/DME x 1% ground speed =
CALCULATION
lead radials"
Sg 4, fr 7, p1
3.
Begin 1/2 SRT at the determined lead radial
and vary AOB as required to intercept the
outbound/inbound radial
4.
Check status of turn and vary AOB to
intercept desired radial
