January 10, 20215 yr Is it normal/real? When I go into the clouds the speed is about 20kts less, with GA planes. Missing the PMDG DC6 in MSFS 2024 (she's here, but...).

January 10, 20215 yr seems like a simulation of wind shifts near large cumulus systems. It doesnt happen with all clouds. Its just a simgame. It can't be "perfect" - whatever "perfect" might be.

January 10, 20215 yr I haven't noticed this yet, at least not something I couldn't explain. What speeds are you talking about, BTW? Ground speed, IAS, TAS? The density of air in clouds is different, which can explain a small speed difference, but not that much. Ground speed can change quite suddenly when wind direction changes. down/updrafts around clouds can have an effect too. And icing off course. You could easily loose 20kts when you've accumulated enough ice.

January 10, 20215 yr It seems the effect is a bit exaggerated, such as the windscreen icing effect and the effects of the wind with the aircraft on the ground, but there could well be a slight difference due to the reasons orchestra has mentioned above. I was quite surprise to find that the water vapour in clouds is actually LESS dense than normal air, so that would show a reduction in indicated air speed. Twenty knots seems a lot though and I have never notice it that much. Edited January 10, 20215 yr by bobcat999 Rob (but call me Bob or Rob, I don't mind).

January 10, 20215 yr As mentioned, this is a bug. I started a thread on the main forum to vote on... alot of people will argue with you and say it is wind, or ice. No it aint! Take an airplane up on a 20 celsius day through a thick cloud layer, and like the OP said it will reduce speed up to 20 knots. It has been one of the most annoying bugs in the sim for me... means you can't fly in clouds with GA. IRL, you could never, ever perceive speed changes due to clouds alone. Anyone suggesting this is remotely realistic is wrong.

January 10, 20215 yr I had the hardest time climbing in the A320 a few patches ago and couldn't figure it out...now I see if I get to about FL25 - 27 and I am in clouds I really have to cut back on the VS. If there are no clouds and I am at the FL its not nearly as difficult. Doesn't seem that realistic but as usual now that I know what is going on I can plan for it.

January 10, 20215 yr The Working title guys are also aware of this bug, as it was puzzling to them when they were flying the CJ4 through clouds. They have a ongoing relationship with ASOBO and did say they were going to make sure they are aware.
