How Cold Weather Helps Your Planes Fly Better

It’s no secret that planes are most comfortable flying in warm air. But did you know that colder air can actually help your aircraft fly better?

In this post, we’ll talk about how the temperature of the air affects a plane’s performance and why cold weather can actually be a good thing for pilots.


A drop in temperature means a drop in air pressure.

It’s simple science: when the air gets colder, it can hold less heat energy, so its molecules move more slowly. That means they collide less often and don’t exert as much force on surfaces around them, such as your plane’s wings or fuselage. 


It could cause less drag on your plane (and thus more lift). A similar effect happens when you’re flying at higher altitudes, where less pressure pushes down on your aircraft—the lower-density atmosphere causes you to lose some lift and gain some speed.


Decreasing the air pressure reduces the amount of drag on the plane.

That’s because there is less resistance for it to push against as it travels through the atmosphere. Less drag means that planes can reach their destination faster and with increased fuel efficiency.


The decrease in air pressure has another important effect: it increases a plane’s weight, making it harder to generate enough lift while taking off or landing on a runway. Just like driving a car, adding more weight to your vehicle (such as putting luggage in your trunk) makes things much harder for your engine to get up to speed.


And this same principle applies here! When airports are located at sea level or very close by, they use shorter runways to accommodate heavier aircraft with greater ease.


However, when airports are located at high elevations (elevation above 7,000 feet), they need longer runways so as not to hinder takeoff and landing operations.


That slower speed also means planes need less fuel to fly in cold weather.

In short, the denser cold air provides more lift for planes to fly with. And as we all know, a lift is just a fancy way of saying that an aircraft can fly. 


So, as you might have guessed from the title of this article when it comes to flying in cold weather: more speed equals better performance.


That means that you can decrease your fuel consumption and save money by flying at slower speeds during winter months. But there is one catch! 


Increasing your speed may generate more takeoff power and create a faster climb rate out of an airport. Speeding up your plane could also cause negative side effects, such as stalling on takeoff or landing due to lack of speed during ascent or descent, respectively.


In all, the colder winter weather is good for your light aircraft. And as long as it doesn’t get too cold and cause ice on the wings, you’ll be able to enjoy your flight even more!
