Performing ILS07R VHHH landing, wind calm, LOC/APP set, wanted to achieve autolanding. Before 400 ft, things went well, flaps, gears ready. But, at about 350ft, the 744 started to turn wildly, rudely to left, leaving the ILS track and Glideslope, (with autopilot). Finally, the aeroplane crashed. Playing with IVAO, ActiveSky, PMDG v1.1, PMDG sound track. Playing GE engine (KLM) from EHAM to VHHH

Sounds like wake turbulence to me as you did mention you had AS.

Too add, if it is wake turbulence it's not a bug. Please make sure you have wake turbulence disabled in AS.Also, as in any landing it is up to the PIC to be ready to quickly perform a missed approach when the approach becomes unstable (either automated or taking over manually). :-)

Do you have the great freeware VHHH add-on airport? By Thomas Kwong I believe.The one issue I have found with that scenery is the very thing you describe. I'd need to have a look at the AFCAD file but it's almost like another ILS beam in the area on the same frequency.

Also, I had my wake simulation on during flight, but I had already disabled it before landing

Well I have Thomas's scenery but not any real weather programs, so I'd say that's the source of the issue.

The problem I think is that , the ILS magenta started to jump to left and up, as the 744 wanted to chase it back, it turned left and climbed, causing this odd behaviour. The final approach did not have any problem

>>>The problem I think is that , the ILS magenta started to jump>to left and up, as the 744 wanted to chase it back, it turned>left and climbed, causing this odd behaviour. >>The final approach did not have any problem>>I am again stunned ...4,4 NM final - 1150 ft - AND 198 kts IAS - flaps 1 - gear in transition ( in my computer the gear won't go before flap 20 ....)You are in trouble . . . and only 15700 LBS of fuel left ( which is realy not much to reach Canton with 30 mins holding required )!
