That could be the case, the person that was telling me the story said he learn't to fly by the seat of his pants in his dads crop duster, using gut feeling and feel , rather than fandangled instruments.
Well its all a matter of perspective, if your head is in the cockpit watching the guages, you will miss the big picture, all pilots have to maintain an instrument scan, and most aircraft I have flown have the old "sacred six", airspeed, altitude, turn and bank, attitude gyro, vsi, and heading indicator. You have to maintain your scan, while maintaining situational awareness of the aircraft and a scan outside for other aircraft, obstructions, and navigating etc, etc. Hence the advent of the HUD on fighter aircraft, it is a game changer, although I really don't like it as well for basic instrument flying, and yes I have spent a little time under the hood. One of the basic flight test checks is "unusual attitude recovery", the drill is the student is under the hood, and lowers his visual scan to his lap, while the instuctor takes the airplane and puts it in an attitude from which it "must" be recovered, it could be a climb or dive or any combination of bank or pitch. The aircraft may be on the verge of a stall, with an extremely high nose up attitude, throttle at idle, or in a dive, in a steep bank, full throttle and airspeed approaching VNE. The instrutor then states, "you've got the airplane" and you must recover, referencing only your flight instruments. Now it is likely that the flight instructor went through several oscillations in order to confuse your sense of equilibrium and spatial orientation!
What your old head was trying to say was that he had an educated butt, and yes that definetly makes you a more capable pilot, you know what the airplane is saying, not just some instrument indications, and as my little tale of unusual attitude recovery illustrates, you have to process information on your main-frame from every source, in the case of the unusual attitude your inner ear will lie, due the fluid being sloshed around, thats why you may be dizzy after hitting your head, or having an inner ear infection. I had ear surgery to correct a broken ear drum, flying a friends Cherokee Arrow at altitude and couldn't valsalve, or clear the pressure due to summer allergies, in the process the Dr. nicked my inner ear, and my head spun for a week, even after he patched my inner ear, I had vertigo for months, so driveing I felt like I was constantly turning left, I had to retrain my brain by following my eyes instead of my inner ear, much the same as instrument flying. Rather than wait to get back in the airplane, I got right back in it, and yes it was very weird, but it was fine.
