Seeing is Believing: Learning to Respect Spatial Disorientation

One of the best lessons I ever received from my flight instructor was a lesson of disorientation. It was fairly early in my flight training. We took off from Santa Monica airport one late afternoon in the early summer. The weather was perfectly clear with light winds, but there was a thick marine layer slightly off the coast. Due to the LAX flight paths, we had to hug the coastline. As we skirted the Malibu beachfront on our way toward the Simi Valley practice area, my instructor Jason Van Camp said: “Let me show you something.”

He told me to close my eyes for a few seconds. While I had my eyes closed, Jason pointed the airplane toward the Southwest, aiming it straight for the marine layer. He also put the airplane in a slightly banked attitude. The point with the exercise was not unusual attitudes. It was to see the hazards of poor visibility and disorientation.

Once he told me to look up, I opened my eyes and was astonished at what I saw. I had no clue what was up or down. And being inexperienced with the instruments, I had no way of figuring it out. My inner ear was no help. It was unnerving. And while the experience was uncomfortable, it truly taught me to respect spatial disorientation.

Too many pilots get killed every year because they fly into clouds inadvertently. According to the latest Air Safety Institute Nall Report, 518 deaths were caused by VFR flight into IMC conditions in the past 10 years. It’s one thing to get under the hood and having an instructor put you into an unusual attitude. It’s quite another to see what it’s really like to be in the clouds. Even if you have no interest in getting your instrument rating, I highly recommend getting into an airplane with an instructor and getting into the clouds. It will teach you never to trust your inner ear and never to get into the clouds without being instrument rated and current.

My flight instructor did it starting in a straight and level trimmed aircraft condition. Even listening to change of aircraft engine noise and the feel I was way off course, losing altitude and at a slight bank angle. Fantastic lesson and it sticks in your mind and a good lead on to VFR night flying. Especially valuable when you are flying at night with a 747 going overhead. Even with the 1500 ft. separation with the strobes and noise there tends to be marks in your undies upon landing.

Back in 1974, my instructor started hood time on my second lesson. Subsequently, every lesson had more, and more challenging hood time. Saved my bacon. On my solo cross country at 18.6 hours, I had to choose between an off-airport landing and climbing through an unforcast cloud deck. It was like the man was sitting on my shoulder shispering in my ear and the climb was uneventful at 70 kts and zero course deviation. 4 years later, I gained an honest instrument rating but the original training never left me. I can hear his sage advice today.

Decades ago, departing PHF on RW2 into the blackest night I have ever seen. All was fine as long as I could look over the nose and see the departing runway lights. The lights went out, the feeling of panic, and fortunately logical thought returned and focussed exclusively but imprperly on the artificial horizon. At 400 feet, this saved the day, or perhaps the night.

I wonder how many accidents could be prevented with a couple of hours of real flight dual every year rather than a third class medical which provided zero evidence of adding to safety, but does make the FAA feel good.

One embarrassing flight I had as a military helicopter pilot in Germany one day left me glad to have been instrument rated right out of school. Flying along on a parts mission I found my VFR route blocked at the beginning of a mountain bordering my intended landing zone. Little did I know as I approached a thickening cloud layer; I was being surrounded from the rear with no room to turn back. Yes having to declare an emergency for inadvertent IMC was embarrassing but the recovery saved my life. Knowing what I know today; I would urge all VFR pilots to at least know how to use the instruments, they may save you one day, and it leaves you with options you would not have otherwise.
