One of the more interesting thing about licensing young’uns to drive is the idea that a license to drive a car is a license to drive any car they make. You can get your license in a Mini and then hop in a Porsche or a heavy-duty pickup. You don’t have to be rated for the different behaviors these different vehicles exhibit.
When you get a pilot’s license you have to at least take-off and land a plane 3 times with a pilot rated for that plane before you can fly it solo. And being licensed for a single-engine plane doesn’t mean you can fly a multi-engine plane. You have to do much more to get licensed for each type than just take-off and land 3 times.
I can’t imagine what it’s like to learn to fly one of the big air buses. The cockpits are mega-intimidating!
