Having done the full procedure a couple of times at Marka per the FMS myself I did not have any issues. Maybe I was just lucky and the area was not hot?
Nimer, you say the procedure turn should be within 5.5 DME AMN, but looking at the Jepp plate it states the turn should be initiated at 5.5 NM, in other words impossible to stay inside 5.5. If this is incorrect maybe local ATC should contact Jepps to have it revised. Not sure how one would be able to turn a jet within D5.5 and still be properly aligned for the intercept though.
Also, you mention being on a heading of 156 in the procedure turn. Maybe I misunderstand you, but can you please tell me your reasoning there. All I see is 106 outbound/286 inbound in the turn.
