If the distance remaining equals the distance already flown, the closing angle equals the track error angle for the same lateral displacement.

### Why this is right Both angles use the same lateral displacement. When the distance in each calculation is also the same, the 1-in-60 formula gives equal angles. ### The concept Track error is calculated using distance flown, while closing angle uses distance remaining. If those distances are equal, the ratios are identical. Therefore, the total destination correction is twice the track error angle. This shortcut applies only when the two distances are equal and the displacement used is the same. ### Terms - **Track error angle**: Angular error estimated using distance already flown. - **Closing angle**: Angular correction based on the distance remaining to the intercept. ### Remember Equal distances and equal displacement give equal angles.
