When you're approaching an airport for landing, visual aids matter for experiencing a safe touchdown. Among the most useful tools are PAPI lights (Precision Approach Path Indicator lights). PAPI provides instant feedback to pilots on their approach angle.

Let’s get into how PAPI lights work, why they matter, and how they compare to similar systems.

Curious about wingtip vortices and how they work? They’re spirals of air caused by pressure differences on an aircraft wing, creating induced drag that affects performance. Winglets, those angled extensions at the wingtips, help reduce these vortices and boost efficiency.

Let’s dive into the details!

Bernoulli’s Principle is important for many reasons; airplanes wouldn’t sail through the skies, carburetors wouldn’t deliver fuel as well, and your favorite soccer player’s iconic curve shot wouldn’t bend the way it does.

Bernoulli’s Principle is the cornerstone of how fluid dynamics shape the world we live in. Let’s take a look into this principle to understand why it matters so much both in and outside of aviation.
