On A320 and I believe on all modern airliners you are never climb gradient limited with all engines running. So you can always use the lowest minima applicable to your aircraft. When you do the landing performance computation, it will give you the climb gradient in case of engine out. If in your case, if it’s below 7%, you still use the lowest minima but you have to mention that in the very unlikely case of an engine failure below 1332 feet and you have to perform a go around then you must follow the EOSID and not the standard missed approach from the chart. The only reason to use the DA of 1332 would be if you had an engine failure before starting an approach and you don’t have an EOSID for HK which is very unlikely. In HK, it’s better to request 07R in case of engine failure for landing if you are climb gradient limited as it’s 4% instead of 7%. The EOSID for 07L is a total mess.
