localizer approach and gs intercept altitude

[Matt]

Hi everyone. 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!

6 NM from runway threshold to MAP? Maybe I'm just tired.

Just follow the procedure

[Matt]

Yes, you are right. It should be 0.6, not 6.0.

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.

Unless the step has a max altitude you may use any altitude above the
min (including the GS altitude).

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.

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.

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

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.
