D.

Intercepting a radial from an arc lead point calculation

1.

Estimate the ground speed

2.

Apply the following formula to determine lead radials:

“60/DME x 1% ground speed = lead radials”

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
