Computes the lead angle in degrees for intercepting a DME arc from a radial.
The lead angle tells the pilot how many degrees of radial change before the
desired arc intercept point to begin the turn onto the arc.
Uses the turn radius at the given TAS and bank angle to determine how far
ahead of the arc the turn should begin. Defaults to 25 degrees of bank if
not specified.
