Learning to fly a plane is easier than having someone learn and explain the different airspace’s, the requirements, and limitations.
The task of starting the plane, taking off, flying level, and landing pretty much a monkey can learn. The weather, ADM, regulations, aircraft systems, weight and balance, navigation. Those are the things I see a decline in. The amount of pilots that I know that can’t fly to another airport 25-30 miles away from their home airport, that are afraid or unable to do that without GPS or ForeFlight. Even though they have been to that airport multiple times is amazing.
