4. The GS fluctuations are reported via a Digital ATIS....you can get this outside of VHF coverage unlike other airports...so you can spend the 2-15hrs of your flight inbound coming up with a plan...there is no surprise here.
5. If you still choose to fly an ILS, you have accepted the risk, best have a plan if you encounter an aircraft upset event. Your decision.
6. If anything needs fixing in HK, it is the extremely inefficient airspace....particularly for arrivals from the north....and there is a 3rd runway under construction.
7. GS fluctuations during single runways ops in the late night period in VMC is a minor issue easily managed by experienced crew....ie don't fly the ILS!
5. If you still choose to fly the ILS WHILE ON THE A/P you have accepted the risk.
Glide slope blanking by aircraft taking the runway is common. As is LOC fluctuations as a plane clears the runway. This isn't new.
Are those sink rates and altitudes correct? 2,600 FPM at 1350'? 1,900 FPM at 525'? Who's minded the store?
If the ILS signal, or autopilot, gets twitchy it's taken out of the loop ASAP.
