Any pilot with a modicum of aviation knowledge, can understand the online aviation products without LM intervention.
I'd argue that with a grain of salt. How many folks pop up here asking if they can make a flight five days from now, and don't realize the tools simply aren't always there to make that determination?
I feel lucky I got to take two college level meteorology courses in my past -- and I try to share a little of that knowledge but I also know I'm not even close to passable as a "forecaster".
I'd much rather walk into a building with a student and talk to a real meteorologist on one of those "iffy" days looking for reasons to go or not go, than try to coach someone through it. Obviously as a CFI I will not have that option. All I can do is explain it as best as possible and try to teach judgement capable of saying "That airport down there looks a lot better than being up here right now."
People with tight modern travel schedules to keep, tend toward forgetting that you might be able to do HALF the flight, land somewhere you didn't plan to land, and then re-assess and continue the flight as a new leg of what's remaining, after the weather problem passes on by.
But there's days I'd much rather talk to someone like
@scottd or hope he's taught a computer what he knows, than try to figure it out myself.
That was probably one of the "ah-ha" moments in the Instrument rating for me, too... when
@jesse showed me that the decisions on weather get *harder*, not *easier* when real IMC snuck into our training schedule. That experience is literally invaluable. "Can we really go in this? Where's the freezing level? What's our out?" It gets your attention a whole lot more when it's not simulated.
