Women can fly and talk
but for most men RT is hard work.
I often wondered if there was a better way to teach RT. The way it is done currently (mix it with flying training) makes one learn flying a lot slower than if no RT was needed. It really ups the workload.
In general I think one learns little in the air, especially procedural stuff like RT and instrument flight stuff. Training should be done on the ground, consolidation takes place in the air. So there should be a real RT ground school. I doubt the industry wants this however, since there is no clear charging basis for ground school (which is why most schools don't do any ground school). And the industry is what the CAA listens to.
