 INSTRUMENT NAVIGATION
In Figure 28, if we wanted to intercept the 330°R we would apply rule two. Since we are
presently on the 350°R 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 310°R, 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)
