I will assume that the DME values in the Approach profile are the slant range and the distance given in the table below is the lateral distance. But I will not forget the possibility of inaccuracy or rounding calculation. | |

But to make all the lateral distances sum up correctly, perhaps the designer had a reason to round the 0.13 up to 0.2 instead of the usual convention. Or it's simply an error. | |
