Computes the crosstrack correction angle using the 1-in-60 rule. Given an
off-course distance and the distance flown, returns the angle in degrees
needed to correct back to the desired track.
The 1-in-60 rule approximation: 1 degree of track error produces roughly
1 NM of displacement per 60 NM of distance flown. This is accurate for
small angles (under ~10 degrees).
Parameters
offCourseDistanceNm: number
Distance off the desired track in nautical miles.
distanceFlownNm: number
Distance already flown from the origin in nautical miles.
