Interesting mystery in Hong Kong

In October 2019, a Virgin Atlantic 787-9, as VS-206, was on an ILS approach into Hong Kong. As they got to waypoint RIVER, the aircraft suddenly veered to the right and descended below minimum safe altitude for the sector. The crew disconnected the autopilot, and were able to reestablish in the localizer and landed safely.

What makes this interesting is that this is the fourth similar event, all near the RIVER waypoint. In July of last year an Ethiopian 787-8 lost control. In September, an Etihad and another Virgin Atlantic 787-9 both veered off the localizer and descended below minimums. Investigators are looking at all the data to determine if it's something on the aircraft side, or the ground equipment causing it to happen.

Did you not post about a month ago about how some airports and aircraft autopilot systems were not linking up correctly?

Connection maybe?

One of the theories is something about the 787 systems, and possibly terrain. That approach apparently is more difficult and has high terrain near it.

I don't know HKG to well, it's out in a bay. Aside from normal hills terrain, would skyscrapers disrupt the autopilot?

See, all water except North bay as your suggesting.

One of the approaches goes towards the mountains before turning and paralleling them.

The waypoint in question is here. You can see the terrain around it. All the incidents have occurred at this point.

Got to be something to do with the 787 I'd say as that seems to be all it's affecting.

There's something about the glide slope antenna setup that's causing it. I would hazard its getting some kind of reflection that's causing a false glide slope. What I cant say.

I suspect you're right. Interesting that the 787 is sensitive enough that it's affected where others aren't.

Interesting, and scary. I've seen many discussions on here about how dependent pilots are on automation. All it takes in a situation like this is the pilots not immediately realizing what's happening and you've got a crash.

Thank God I don't have to fly anymore.
