Navigation

[Guest]

I can fly on NDB's, VOR's,GPS is like walking down the street.Now, if I get to my waypoint,try for the ILS approach,I can not find the glide-slope. must I find the outer markers with the red rings? {in the GPS map}?

I suggest the aviation section of www.stoenworks.com Look for an article entitled "Flying the Coupled Approach." There are many other articles that you might find helpful.

The service volumes (area in which the signals are useable) for localizers and glide slopes are relatively small.Localizer coverage is between 10 and 35 degrees either side of centerline out to 10 miles and only 10 degrees of centerline out to 18 miles. Glide slope is typically only useable out to 10 miles.If you intercept the localizer 18 miles out, you would still be outside the range of the glide slope. Have patience ... it will come in.The other thing to be concerned with is the glide slope intercept altitude. The standard glide path is 3 degrees. If you are too high on approach you may never get a glide slope indication because the indicator just stays stuck at the bottom! Normally the intercept altitude at the outer marker is 1400' AGL (although many approaches actually intercept the glide path slightly outside the OM). You should always try to capture the glide slope from below. If you don't have proper charts, I would descend to approx 2000' AGL about 15-20 miles out (only try this in the flatlands!!) to pick up the localizer.I would really recommend getting some real approach charts (many online resources) and flying the procedures as published. It's a lot easier (and safer!!) than trying to slog it out on your own.

here is the PREMIER site for learning navigation (my opinion of course)http://www.navfltsm.addr.com/
