Is it me or am I seeing double  :(

Remember ILS needles are for guidance only, once you get neerer they will get techy.  The important thinf to remeber is not to chase the needle or you could find yourself going in circles.

The sensitivity of the Localizer at 5.6 miles is 775' for one dot of aircraft displacement. At 1/4 mile it is 215' for one dot.  Even the 172 flying at 75knots, covers 110 feet per second (forward movement). Since the width of even the widest runways is usually 150feet(50m), you can see how it is neccesary for such tight tolerances.

Go to this site: http://www.navfltsm.addr.com/index.htm and do the lessons therein. He even has a very nice modified 182 for you to learn in. Once you go through the lessons you will fully understand aviation navigation. ;D
