What do the United States do in their syllabus for this issue? (although I note it was mentioned above that their crash rate is high)
Maybe including a NVFR rating in the PPL syllabus (like in the USA) would help with flight planning for bad weather and the usage of instruments?
I wrote to JMc about this years ago but I didn't get an outcome due to the changing of the guard at the time.
Current requirement is 2 hours IF.
