It probably depends a lot of what "natural feeling" means to you. The way a Westerner who's educated to sit on chairs for long periods of time in school deals with feeling gravity is far from natural.
If you interact with gravity all wrong and are suddenly put into a complicated situation while flying a plane as a pilot than that will reveal a lot of problems.
It would be interesting to compare different beginner pilots and the way they interact with gravity and see which one's do a better job.
I think it's because humans can easily confuse the pull caused by gravity with a pull caused by acceleration. We could tell the difference using the visual cues when we run or jump... but if you are sitting in the plane, the plane moves together with you, so all objects inside the plane are constantly giving you the wrong cues.
In other words, the plane is "far from natural". Not being from West doesn't help a lot here. Perhaps coming from an alien civilization where kids spend most of their time in flying saucers would make a difference.
