INSTRUMENT NAVIGATION

In Figure 28, if we wanted to intercept the 330R we would apply rule two. Since we are

presently on the 350R and we desire to be on the 330 R (20 left of 350) we must turn the

aircraft 20 left of 330 to 310. Once established on a heading of 310R, the tail of the needle

will move left and eventually reach the 330" R.

Figure 28

Now let us shift our discussion to tracking inbound on a radial. Tracking inbound will differ

in some ways from the techniques you have already learned. Instead of using the tail of the

#2 needle you will now be using the head. The head behaves in a manner different from the tail.

Rule Three: In order to intercept a certain course, determine how many degrees to the right or

left the head of the #2 needle must move, and then turn that same number of degrees to the

opposite side of the head of the #2 needle. (i.e. the head falls)
