First off GREAT aircraft! now to my problem/lack of knowledge. When cruising and I want to descent to a lower altitude I first select the lower alt value and arm it, then press "IAS" and start pulling back on the throttle. Is this the correct procedure? (like the CRJ-200) when I do this the plane will not descend and the IAS does not hold. I have also selected "VS" and then use the pitch wheel but that didn't help either. I must be doing something wrong or out of sequence. Thanks!
