When flying with real world weather on my FSX, I find that when I am descending, I get these constant "hic-ups" with my alt and speed gauges.

I have the winds and turbulence disabled yet continue to get these jumps (every second) in alt and speeds.

Is there something I can do to prevent this from occurring?

Thanks in advance.

I believe this is an FSX weather bug, which can be resolved by using better weather add-ons or wind smoothing of a program such as FSUIPC. I also experience rapidly alternating winds, which sound like the ticking of a clock.
