As this issue has been discussed many times at recurrent (Global Express), is there an express prohibition on FAR 91 operators using the MDA as DA, IAW the note on the Jepp chart? Where is it?
Most FAA NPAs that have straight-in minimums have the advisory vertical path coded into the procedure's database, RNAV or not (exluding LOC or LDA). Thus, any operator with the requisite avionics can use that vertical path. But, without the stated authorization they cannot treat MDA as DA.
It is a very fine line, indeed.
The requirements for the authorization are contained in some obscure advisory circular and, I believe, is limited to qualified commercial operators.
So, you might ask, why doesn't this IAP simply have a line of LNAV/VNAV minimums with a charted DA? Most likely because the runway's close-in obstacle environment did not pass muster for the FAA glide-path qualification surface (GQS). Also, in this case the descent angle of 3.14 degrees is beyond the limits for Approach Category D.
