Visible shockwave on a A320 wing. A transonic shockwave forms when locally supersonic airflow over the wing must suddenly slow to subsonic. This abrupt deceleration creates a sharp pressure jump. 📹: u/sweepinglama

Shockwaves can become visible on an airplane's wing during a turn under certain conditions. Commercial jets cruise in the transonic regime (Mach 0.8–0.85), where airflow accelerates over the wing's curved upper surface, creating local supersonic regions despite the aircraft remaining subsonic. This forms a shockwave as air abruptly decelerates to subsonic speeds. The shockwave appears as a shimmering or wavy distortion due to sudden density changes that alter light refraction, similar to heat haze over a hot road. In a turn, banking increases the angle of attack and wing load factor, further accelerating upper-surface airflow and making local supersonic regions—and thus shockwaves—more pronounced. Passengers often report seeing these "dancing" shockwaves move, split, or intensify during maneuvers. Visibility requires sufficient humidity for condensation or good lighting/contrast for density refraction. In dry air, the shockwave may exist but remain invisible. Video and info via u/knowitokay

Selection conversation must have been funny this week for Garry Ringrose - “you play on the wing” - “ya”. “oh & can you jump at 2 on a 5m lineout”...... #LEIvBAT

Bernoulli's Principle It’s a key idea in fluid dynamics named after Daniel Bernoulli. In simple terms: For a fluid flowing smoothly, an increase in the fluid’s speed happens at the same time as a decrease in pressure or a decrease in the fluid’s potential energy. Where: - P = pressure in the fluid - ρ = fluid density - v = flow velocity - g = acceleration due to gravity - h = height above a reference point Bernoulli's Principle basically says that for a fluid that's flowing smoothly, when its speed goes up, its pressure goes down. Think of it like this: fast-moving air or water pushes less sideways than slow-moving air or water. The energy in the fluid stays the same overall, but it shifts between motion, pressure, and height. That's why an airplane wing creates lift. The air moves faster over the curved top of the wing than underneath, so the pressure on top is lower. The higher pressure below pushes the wing up.

An Airbus A380 climbing through the clouds and leaving behind spectacular wingtip vortices. These swirling trails are created by pressure differences between the upper and lower surfaces of the wing and become visible when moisture in the air condenses. 📹: schipholhotspot
