The Reasons Why Most Commercial Planes are Painted White

Ever found yourself pondering why the exterior of most commercial planes, such as Philippine Airlines, Cebu Pacific, and AirAsia, among others, are painted white for majority of the fuselage? Indeed, this is not just a random occurrence or a mere matter of aesthetics. This pattern transcends across airlines around the world, including Emirates, Cathay Pacific, Air France, and Qantas, all showcasing aircraft with predominantly white exteriors. Despite a handful of exceptions like Korean Air, Play, Southwest Airlines, and Air New Zealand, the majority of the aviation industry does indeed favor white. This prevalent color choice isn’t arbitrary, as there are concrete reasons behind airlines favoring white-dominated liveries.

Reflecting on Radiant Heat

One reason why commercial airplanes are predominantly painted white or light color coating comes down to basic science. White, being the ultimate reflector of sunlight, bounces back the sun’s radiant heat instead of absorbing it. This helps to maintain a cooler and more comfortable temperature for the passengers and crew inside the aircraft. Just like tennis players don white outfits to stay cool under the sun, airplanes use the same principle to ensure a more pleasant journey for everyone on board.

Spotting Aircraft Damage

There is another practical reason behind why majority of planes are pained white or lighter shades when painting aircraft. Visual inspection of an aircraft’s surface is a significant aspect of routine maintenance checks. Light colors, particularly white, make it easier to spot damages such as dents, corrosion, rust spots, cracks, and oil leaks. This visibility allows for quicker repairs, helping to prevent further, potentially more severe, damage. It’s also a way to save both time and money in the long run, a crucial consideration given the lifespan of commercial aircraft.

Aesthetic Appeal and Resale Value

White has long been associated with a clean, sleek, and modern aesthetic, making it an attractive choice for many airlines. This color not only enhances the aircraft’s appearance but also affects its resale value. Aircraft painted in darker hues tend to fade over time, requiring more frequent repainting, which can be a costly endeavor. Additionally, a darker-colored airplane generally has a lower resale value compared to its lighter-colored counterparts, making the latter a more economical choice for airlines.

The Feathered Factor

Bird strikes are a surprisingly common and serious issue in aviation. Lighter or white aircraft tend to be more visible to birds, reducing the chances of collisions. Although a bird strike might not seem overly consequential, it can result in significant damage and potential safety risks during a flight.

An Exception to the Rule

Though the rationale for white planes is compelling, there are exceptions. Air New Zealand, for example, is known for its fleet of black planes, making them distinct and easily identifiable. Yet, such exceptions only underscore the general rule.

The weight and cost of painting an airplane are substantial considerations for airlines. Using less paint by sticking with a white base not only saves weight, translating into fuel savings, but also makes the transition easier and less expensive when planes are sold or leased to other carriers.

From reflecting sunlight to spotting damages, aesthetic appeal, resale value, and even preventing bird strikes, the predominance of white in commercial aviation is more than just a matter of aesthetic preference. It’s a practical, cost-effective choice shaped by a range of considerations, an embodiment of the adage “function over form.”
