Low frequency roll oscillations with UNS-1

[FD1003]

Hello, I encountered some low frequency roll oscillations with the UNS-1 on the BAe 146- at first I thought it was wind, but if I got in "roll" mode the oscillations stop. I made a video with the oscillations where I also show the current weights and the wind (as calculated by the UNS-1 FMC)

@FD1003 Thank you for reporting this. This isn't something we have seen reported before, but we will investigate this and if we can reproduce it, we'll include an improvement in an update to the 146.

@Mark No problem - it's a very small issue anyway, appreciate your response. You did a wonderful job with the update

In fact I have experimented the same rolls with a 146-100 with no cargo and no pax in quite ordinary wind conditions. I'm using the modern FMS. I've tried several configurations of speed and altitude with no success.

It likes to do pitch oscillations too, especially at lower speeds. I flew into EGLC now, and on the last legs of the approach as the plane slows down to 210 and then 185, it becomes a veritable lowrider. GS was completely useless so I had to hand-fly the whole thing. At higher speeds it was perfectly fine.
