On a local flight in your area if you've flown for awhile you have an intuitive feel for the weather and terrain conditions. You have a fairly good expectation of what the weather will do and what changes you can expect. Remove yourself to a distant part of the country or world and that expectation falls apart completely. It is better now than when I started flying because of the profusion of cockpit weather products. But that intuitive knowledge is still missing. Us flatlanders don't understand mountains, someone from the midwest may be clueless about flying over coast or water, and other issues. Thus in my own opinion a long cross country flight is nothing whatsoever like a local flight.
I might add that a long flight involves issues almost never encountered in a short flight, including maintenance away from home base, diverting due to weather, and a host of other issues. They are nearly apples and oranges in my opinion. And that is what I have stated, my opinion. But to me telling students that a trip across the US is just like a bunch of milk runs strut together is a blatant misrepresentation, again in my opinion.
Indeed your example is quite illustrating. Someone who grew up in Florida won't know a damn thing about flying in mountains, snow, icing and a whole other bunch of issues.
Hmmm. Interesting points.
Of course while we all know the reality is that, say, a mountain lubber such as myself WON'T know say, coastal fog... not from experience anyway...
Do you think anyone should be signed off for a Private checkride without at least a passing knowledge that coastal weather exists, even if they've never seen it, and since their role has now become Pilot In Command, they'd better look up or talk to some folks who understand it before they go fly to a coastal location from their land-locked high plains existence and life knowledge?
How about by the time they earn an Instrument rating? Commercial? ATP?
Ever met a Private Pilot who wasn't told they "now have a license [sic: certificate] to learn"?
I think about this stuff a lot as a newbie instructor.
I need to get the point across that there's regional weather and things a pilot from "here" won't know "there", but their base knowledge (how to read a weather forecast, map, radar, METAR, TAF, etc etc etc) HAS to cover 90%+ of what they need to know -- and then they have to gain experience on their own. I can't often take them to a coast and show them a marine layer. I can at best show them a photo of it or a video.
The cell phone will always be on too, if someone really has a question -- "Hey, I'm seeing something I've never seen before... and want an opinion..."
I really do think with the basic building blocks learned in the Private rating, someone CAN treat a long XC as a few shorter ones. But they also have to recognize they don't know the regional weather and perhaps alter their personal minimums and what not as they get further from "home".
Plus, who knows? There are students who are military brats or whatnot, who actually have seen all sorts of local weather all over the country or even multiple countries. They'll know more about it than I will... but the base techniques they need to learn won't change.
I can teach how to read stop lights. I can't teach that done city somewhere isn't standard and flips theirs from green through yellow to red a second faster than the usual/standard. But they can still read the stop sign. Can also give a heads up... "I've heard there are a few weird stop lights out there. Especially in X area. If you drive there, keep an eye out for it."
And I wholeheartedly agree with you. A cockpit is a CRAPPY place to be doing a weather briefing. Cockpit weather is to augment a proper briefing on the ground where one's full attention canbe given to the topic at hand.
I think your statement proves the base knowledge works. You know you don't know mountains. You'd ask about them or plan to go around them if your perfect route would take you directly over the Rockies.
Your students in your classes show up (hopefully, I know I know...) with a base knowledge level but don't know as much about genetics as they will when they leave. There's always levels to knowledge. It's super cliche' to say it, I know... but a good pilot is always learning. Long XCs crossing weather systems is a BIG learning step that most folks have to take eventually. Every airport has someone willing to help if something just doesn't seem right or a feeling of "I need to know more about what's happening here..." is nagging a pilot.
And one can always turn around and go back. The ultimate "I'd rather not get hurt doing this" move. One should never be too proud to bail out and go back the other direction.
Example: If one somehow missed that mountains can be dangerous and one encounters continuous moderate turbulence at the foothills, turning around and landing somewhere and asking a local why... instead of plowing on into the heart of the big rocks... shouldn't be ruled out.
