Just so I understand exactly what you are saying, is it your position
that,
when using DEPRE as the IAF for the purpose of starting this SIAP, if one
is inbound, the legal minimum altitude at DEPRE is 2141'?


There is no Minimum Descent Altitude on an ILS approach, there is instead a
Decision Height. AWI123 is level at 3000 and five miles south of DEPRE, on
the localizer, when cleared for the approach. The aircraft leaves 3000
about 2.7 miles south of DEPRE, where it intercepts the glideslope. It
follows the glideslope down, crossing DEPRE at 2141 MSL, to the decision
height of 882 MSL. From that point it will either complete the approach
visually or execute the missed approach procedure.


I didn't see your response of mine to this post of yours. Perhaps you
missed it, or I missed your response. In any event, here it is again:

=======================================

Your answer is not responsive to my question, but perhaps I did not write
clearly. So I will try to be more clear:

I did not mean to ask you about an MDA for this ILS approach. Nor am I
concerned about how the approach is flown from the FAF to DH.

I ask how your procedure without radar vectors satisfies the requirement
that this approach begin at an IAF.

I thought you indicated that DEPRE was the applicable IAF to satisfy this
requirement. Was that an incorrect assumption?

If DEPRE is the applicable IAF, it must have a minimum crossing altitude.
Since traffic is passing DEPRE at 2141', I would have expected that you
would think that is legal when DEPRE is being used as the IAF from which
this approach begins. Is that your position?

If DEPRE is not the applicable IAF, then I don't see how your procedure
meets the requirements of the 7110.65 that a non-vectored approach begin at
an IAF.
