I've checked our Aerad charts for 21 at ACE & I sympathise with the problem. The temporary charts issued Nov 2 00, are for the period that LT VOR is u/s. Reading the previous comments I think all has been said already; it's not the easiest approach & has no step down on the temp charts, however you are starting from a greater alt,(3300 v 3000),but it is not wildly different from say Seychelles or the old HKG 13, where in these cases & others, you must not deviate from the procedure or descend early (ie below the nominal 3 deg path, or in this case somewhat steeper; PAPI is at 3.7deg) or you'll hit something hard. The procedure is offset (14deg left) for an excellent reason which has been noted, so if a/c are turned onto the extended R/W C/L too early you'll be in the wrong place. If the procedure could have been made more straight-forward it would have been. Therefore follow the chart (ours or the others) & don't descend below the nominal path, & only line up with the r/w when 100% visual including all hills.The published DA & the circling MDA will keep you above high ground if you follow the procedure. An approach to be very carefully flown. As a result of these comments we are checking our ACE charts to ensure the obstructions / MSA contours are as carefully marked as they should be.
