isn't the whole point the need for training to proficiency and not just ''you will learn it on the line''?
There is no time to learn on the line. You are either fully competent or not. And the same thing for GA flyers...even more so as they rarely have copilots.
Sadly, engineers who create the gee whiz stuff have forgotten some earlier learned lessons. Buttons, switches and the like use to have specific shapes to remind pilots what did what. Multi use switches can be confusing. (reminded of the collision over brazil and whether the transponder was ON on the biz jet)
iceman...sometimes we don't respond to your points just ''cuz''.
I like the physicallity of moving a bug on the airspeed indicator...making a calculation...but I also want an AOA backup. I know one guy who landed hard...oops...garbage in garbage out...20,000 lbs overweight.
