Hey there,

Just wondering why the indicated airspeed (IAS), isn't the same as the true air speed (TAS).

Is it something to do with atmospheric pressure?

Thanks,

I've noticed that no one answered to your questions and I don't like when questions are not answered, so I found some information for you.
