Hey @NailV123!
Before we go any farther, try removing the “NOT”. That will make the volume adjust only while you are in the air. Right now it is set to only adjust while you are on the ground.
If that doesn’t work, do you think you could try to be more detailed in your question? What is happening, what do you want to happen?
Feel free to try to use a translator, or post a larger amount in your native language and we can try to figure this out!
