This time, exceptionally, I am not going to blame all the world's problems on the ATPL hour builders
These are mostly relatively bright young men who do know how to use the internet - much more so than the older instructors who know as much about the internet as the average person of similar age (not a lot, usually). It would be trivial to get them to teach the material.
They have also (usually) sat the ATPL ground school which deals with weather pretty exhaustively. OK, it does it in a rather theoretical manner and again without teaching how to get the raw data via the internet (GFS in particular) but this is only a short step.
The problem is with the syllabus which is deliberately really really basic.
It is so backward that the mind boggles how much effort must go into keeping it so backward, and who bothers to keep up this pretence that "the olde ways are the best".
Fortunately for the CAA, when they want to prosecute somebody, they can use a GPS to find their way to the courtroom, they can use computers to type up their evidence, etc
Nothing backward in that.
Anybody with some sort of technical education, who enters PPL training, wonders where all this cr*p is coming from and how long they will have to put up with it.
The lack of GPS is the most obvious thing but that's because everybody knows about it, and most reasonably smart people use it elsewhere. But nobody outside aviation will know about internet notam and weather sources - unless they happen to read stuff like this.
The circular slide rule is the second one.
