[Periodic Stutter when using Navigraph Navdata]

Confirmed - had no idea it was this that was causing it

[A350 just took a nose dive into the runway on ILS]

Update: I think this is something to do with activating approach phase and managed speed. I've just done 3 landings in Dubai in the A350-1000 and the first one I activated approach phase, but for the next two I didn't and just used LOC/APPR. 

First landing - wild oscillations at about 500ft

Second and Third - smooth autoland, no issues.

I have this behaviour 100% of the time I don't fly manual landing. Exactly the same as the video quoted:

Here you go. 

Normally I would fly manual but I was just landing into Dubai with limited visibility so left it on autoland. At around 500ft the plane starting oscillating up and down (attack angle would go from 1% to 7% and back again) with massively varying throttle.

Checked all the inputs and this was fine. I can replicate this 100% of the time at any airport (confirmed it happens at Manchester, Heathrow, Hong Kong). However it did not happen until about 3 weeks ago, and the initial build would land flawlessly. 

Happens on 900 & 1000. I've not tested 900ULR yet. 

 

edit: just realised this is the 2024 forum. This is happening on 2020 as well.
