Plotting on the BDHI and using the pencil method we find that 315 is the correct course to

fly from present position to the desired position. (Figure 14)

When a co-DME situation exists, we can forego the pencil method and substitute numerical

computations. Here is the procedure to use:

1. On the BDHI, locate the head of the #2 needle and the numerical value of the radial you

want to intercept.

2. Turn to the heading that is exactly equidistant between the two.

3. Apply crab.

Note that the aircraft is heading 315: equal to the solution of the pencil method (Figure 15).
