14.25 Is there a way to determine the "lead point" for turning onto a radial?

From FlightSim

Divide the DME at which the radial will be intercepted, by 60. This will be the number of degrees per NM at that point on the radial. Convenient #'s are 10, 15, 20, 30, 40, and 60. Multiply the degrees per NM times the turn radius at your bank angle. This gives you the lead point for a 90 degree intercept. For other intercept angles, multiply the computed lead point by a value determined by the intercept angle. For 60 degrees = 1/2, 45 degrees = 1/3, 30 degrees = 1/6. Note that the computation doesn't account for wind, and will change with bank angle. This formula is for a standard 30 degree bank angle.

To determine your turn radius......someday when you're out boring holes in the sky get to your pattern speed and cross a radial and immediatly note the DME and begin a standard rate turn. After 180 degrees, again note the DME. Ergo......turn radius.
