I love Ch. 9! I fly out of my way sometimes to use it as well! Anyway, yes, it is great. BUT, be aware that it is the captain's choice to turn it on, and he may refuse. But, most do. And, if it is not on at the beginning of the flight, just go up to the cockpit and ask, they like hearing from enthusiasts. Also, Ch. 9 is low on the list of things needing to be fixed by the mechs, so it is rare, but sometimes it is broken. Have a good trip!
