We have engine out procedures for the 7s in VHHH in order to meet the obstacle clearance requirements. It's separate from meeting 2nd stage climb. Both of them go NE about 6 miles and turn to a 185 heading through the Ma Wan channel, almost an overlay of the Logan 3 departures. If I lost an engine leaving VHHH and had to shoot the ILS 07L to come back I would tell ATC we are unable the published missed approach and if we miss we'll go to Rover and then turn heading 185. The same thing that made us legal to depart in the first place. If they don't like that they can give us 07R.
