Altitude select erratic

Airbus 320 altitude select. When changing altitude select the altitude moving very fast. to stop it i need to engage altitude . It happen in up or down selection. any solution ?

Can’t help you with the Airbus, but I don’t think you’re going to get a lot of answers by posting this in Flying-World Discovery.

You may want to move it to Self-Service and Bugs.

Use your mouse wheel instead, and if you find it continuously scrolling, click again to stop it.

Thank you for your help. It worked perfectly

I also just had this issue after a 2hr flight.
The Altitude select on the FCU scrolled fast to 1000 ft and aircraft started to dive - No way to move the altitude back to 5000 ft nor level the aircraft.
As I was on the glide slope, I engaged the APPR, but did not respond to the approach mode.

I had to fly the landing phase manually.

I’m using the A32NX v0.4.1 stable release btw.

The fault did not come back on another test flight.

didn’t work for me, but i suspect the mouse wheel triggered it. :+1:

for altitude select try using the mouse wheel only, do not click . It look that the issue is with altitude only. for example changing airspeed by clicking the mouse is OK.

No, it happens to all the knobs. It’s random. Sometimes I got it on altitude, then it stops and I didn’t get it again. Sometimes I got it when I was turning the cabin temperature control overhead. Again click it again and it stops and I didn’t get it again.

I think it just randomly happens to everything with a knob. My guess is something to do with the mouse click input that randomly assigns “toggle” instead of “hold”. That’s why you need to click it again to toggle it off.
