The Argus/Wyvern ratings have very little to do with actual safety. They have much more to do with record keeping and B.S. slinging. I have seen horrible operations get these ratings. Pacific Jet (who broke every rule in the book) was Argus approved. As for Global Exec and Avjet they are actually both top notch organizations (in my opinion), I know the chief pilots and the owners of Global Exec and Avjet., Global is run by pilots and in my opinion has beat down any myths that pilots can't run companies and Avjet has been setting the safety standard in charter for almost 30 years. Unfortunately, when we hire in the Part 135 world we have to rely on pilots experience and training from other operators which sometimes may not be all that great. The Captain of the Avjet aircraft had crashed two other aircraft in his carrier(this wasn't discovered until after the fatal ASE crash) but thanks to good lawyers he had a clean record when he got the job at Avjet, that isn’t Avjet’s fault that the Captain had a protected history of bad decision making skills.
