All these Hongkong incidents of GS fluctuation are handled very unprofessionally risking precious lives without reason. The approach needed to be planned on threat assessment. The good old FORDEC would have you land without problem. What's the threat ? GS fluctuation may cause the AC to dive or climb. What are the options? 10km visibility allows you to do
1. LOC only approach and B787 has even IAN or
2. purely a visual approach or
3. Select ILS but don't arm approach instead use LOC. You can set up required descent you can track GS when OK and ignore it when misbehaving. When visual just go ahead and land.
Is this rocket science? Just flying manually will not solve the problem it will hit sea manually.
