INSTRUMENT NAVIGATION

Figure 3

Always read the computed heading/course FROM your present position TO your desired

point (Figure 3). Failure to do so will result in a reciprocal heading which is an incorrect

solution. This can be avoided by a l w a y s placing the under the

on the CR-2.

By relying exclusively on the computer, without employing logic in the solution, a reciprocal

heading may seem feasible. Such reliance will sometimes cause significant navigational errors.

Do not let it happen to you. THINK!

Note in Figure 4 how your CR-2 calculations agree with your mental picture.
