Approach climb gradient legality
Hi, here is a question about legality on approach climb gradient, taking an example of RWY07L HKG the required gradient for ILS CAT 1 approach is 7% , if the aircraft capability because of landing weight is only 6.25% it is understood that its not legal to fly the ILS CAT 1 , if the only runway available at time is 07L would that be legal to fly an ILS but use (higher) minimums that of a LOC ONLY (GS OUT) approach from the same chart as this is 5.7% only and aircraft is able to satisfy it.
Question 2 , In the same situation would that be legal to still use CAT 1 ILS minima knowingly that the aircraft can not satisfy published missed approach and in case of go around fly the operator's published Engine out procedure instead and inform ATC.

You have to use the DA appropriate to your expected climb gradient. That would mean using 1,230' for a 2.5% climb gradient. I also would not request to use a published EO procedure, even if ATC knew what yours was. And if I did ask, I would not expect them to permit lower a lower DA. But if I had an engine failure on a go around below the higher DA, I would follow the published EO procedure. If that means you can not make an approach, then so be it. Your payload has to be commensurate with performance limitations imposed by the weather and runways at your destinations and alternates.

You might find something in the notes section of the performance manual (landing performance, for the runway in question) that covers this.
Looking at the runway you asked about our manual does give alternative go around procedures (i.e. lateral routings) in the unlikely event (for our type) that you need the "standard" minima but can't achieve the associated MACG.
