Clouds In Your CAVU

For a supposedly CAVU day, I was now pointed at a solid cloud bank. I transitioned to instruments while still VFR and entered the clouds continuing toward VOR #3. It was still smooth as I crossed it and adjusted course toward VOR #4. Shortly after crossing VOR #3, there suddenly were a lot of pilots on the frequency asking for course and/or altitude changes to get out of this weather. I was still enjoying a smooth ride.

Key Takeaways:

A pilot, flying on instruments through unexpected clouds, experienced severe spatial disorientation and blurred vision after a single jolt of turbulence coincided with a quick head turn.
This disorientation led to significant deviations (40 degrees off-heading, 400 feet low) and temporary difficulty interpreting the instrument panel.
The pilot recovered by intensely focusing on the attitude indicator to regain basic orientation and correct the deviations.
The incident highlighted the critical importance of minimizing head movement when flying in or near turbulent conditions to prevent spatial disorientation.

Reading Mike Hart’s February 2019 article, “Losing Orientation,” brought back a not-so-fond memory. As a recently certified instrument pilot, I had started making semi-regular trips to visit my mother. I was flying a Piper Warrior II, but we hadn’t gotten around to installing a GPS yet. So my trip was a series of four VORs up and the same four in reverse to get home.

On the day in question, Flight Service’s briefing basically consisted of, “Enjoy your flight; it’s CAVU all the way.” Off I went and had a nice day and lunch with mother. Late that afternoon, I called Flight Service about the flight home and received the same briefing: “CAVU.” Soon, I was enjoying a smooth ride up at 10,000 feet, had crossed VOR #2 and adjusted course toward VOR #3…and what’s that ahead?
