A pilot's inside joke turned into a statement piece—this aviation tee is made for those who know their way around a flight panel. Featuring six essential cockpit gauges (airspeed, altimeter, heading, vertical speed, turn coordinator, and attitude indicator), this design is bookended by the deadpan phrase:
“WHAT PART OF DON’T YOU UNDERSTAND?”
Whether you're a pilot, instructor, or avgeek, this shirt lets the instruments speak for themselves.
Great For:
✈️ Flight students flexing their new language
😎 Instructors with a sense of humor
🎁 Gag gifts for pilot friends or proud aviation nerds
🧠 Anyone who knows how to read a turn coordinator
