For those of you on the commercial side of things, especially anyone that does long haul international flights, I have some questions about how you guys handle severe weather. Where I'm at right now, there are a lot of thunderstorms and it seems like everytime we go out, there are SIGMETS all over the place for isolated embedded CBs with tops of 520. Obviously nasty stuff and when you look on SkyVector, you see large swaths of massive clouds that go way higher than any airliner is capable of doing. Yet, I look on flight trackers and it seems like commercial aircraft are trucking right along as if they don't exist, or are at least able to find their way through. We have a radar on board that does a decent job of helping us pick our way through, but some of these storms look massive. How do you guys handle SIGMETS and severe weather, especially outside of a radar environment? Thanks for any help.
