I have been flying the pro line 21 package since Raytheon started putting them on Hawker 800s. Cant complain a bit really the only problem is when you got two guys fighting each other over how to run the system. Remember there is somewhere between 2 and 18 different ways to accomplish the same thing on the box thats a great thing and sometimes not so great.
learn the basics LEARN THE BASICS and step down on the automation at the first sign something isnt right because Dogs watching TV will bend metal. Oh BTW when you start thinking your an expert.... the 21 will quickly correct you my friend.
