A quick question from an instrument student: If I am flying a localizer approach where there is a glide slope intercept alitude (lightning bolt) that is lower than the inbound altitude prior to the final approach fix, can I descend to the gs intercept altitude although I am flying the nonprecision approach? For example, on this approach: http://204.108.4.16/d-tpp/0704/00446I20.PDF Can I descend to 2200 prior to Wesie, or do I have to stay at 2400 until crossing the non-precision FAF?

Thanks Matt Matt, In this case, the 2400 is the minimun altitude while in the hold/course reversal. You are good to 2200 when inbound for the LOC approach, until crossing WESIE. As a side note, who else can spot the huge charting error on that plate? Happy Flying!

Thanks Matt You can descend to 2200 when inbound on the procedure turn, or after crossing LEADS if you start the approach at GDM or EEN, but that has NOTHING to do with the GS intercept altitude. 2200' is the charted altitude for the intermediate segment of the localizer approach. You may not descend below 2200' until after crossing WESIE.

That doesn't make much sense to me. Since at WESIE, if you are on the glideslope, you are at 1862, you'd be intercepting the glide slope from above, which is a Bad Thing. Granted, you're probably only four or five dots high (guessing from the graph) but it's still high. Also, the underlined 2200 at teh lightining bolt is not at WESIE, it is at the point where the slope of the course line in the glideslope view changes. This implies to me that you can descend below 2200 once you intercept the glide slope, and at WESIE you can expect to be at 1862.

Thanks Matt Unless the step has a max altitude you may use any altitude above the min (including the GS altitude). -Robert Back to top ArtP Guest Posted: Sun Apr 22, 2007 8:24 pm    Post subject: Re: localizer approach and gs intercept altitude On Sun, 22 Apr 2007 05:29:33 GMT, Jose <teacherjh (AT) aol (DOT) nospam.com> wrote: Quote: For example, on this approach: http://204.108.4.16/d-tpp/0704/00446I20.PDF You may not descend below 2200' until after crossing WESIE.

This implies to me that you can descend below 2200 once you intercept the glide slope, and at WESIE you can expect to be at 1862. The discussion is about the localizer approach (no glide slope). Until you cross WESIE you don't know where you are so you stay at 2200 feet. After crossing you can go down to 800 feet until you see the runway environment. The glide slope will take you down to 521 but this is the localizer approach so you can't descend below 800.

Duh! Yes, of course stay above 2200 until past WESIE. The GS intercept is of no consequence with no GS.

Jose Jose, It seems that you missed the beginning of this thread: "If I am flying a localizer approach..." When flying a localizer approach, by definition you do not have access to GS information.
