The cold weather has its challenges and failures. That, cold. And you should be more enthusiastic about pre-flight inspection, prep, and de-icing. But many pilots love winter flying, not just for its unique beauty, but because their airplane seems better than warmer temperatures. Here is a (simplified) explanation.
First, to clarify: Airplanes may perform better in cold weather, but this does not mean safer. The potential for icing and its impact on lifting and handling is a dangerous threat to freezing temperatures. But the icing, cold air can help planes to take off and fly better.
It is about air density and engine power
So why are airplanes doing better in cold weather? Simple, air is cooler than warmer air, contributing to engine performance and air lift. But why?
Airplane performance, including departure distance, accession rate, and engine power, is greatly affected by air density, also known as the density of the thickness.
In general, both turbines and internal combustion / reciprocating piston engines are operating better in cold air because cooler air permits the engine to use a larger mass of air / fuel mixture in the same amount of use . It means more power.
In propeller-driven planes, the tank is painful in the air, and pushes a broader air upwards, which means more thrust and power.
More power allows an airplane to speed up faster. That extra power increases the rate of climbing, reduces roll elimination, gives wings more lift, and allows the plane to take off at a lower ground speed .
So. It's not really the airplanes that go out better in the cold air; It is that their engines produce more energy when they take off in the cold air. Again, when the air is cooler, and thus more accurate, a larger mass of air can enter engine cylinders at each stroke, and that is equivalent to more energy.
More power also means more fuel
Remember that, while engines are making more power in cold air, fuel increases increases with power. Scientific, wind contracts when it's cold and dense. This means that the air you are taking during the combustion period has more oxygen in it. When there is more oxygen, the engine is paid by using more fuel.
Faithful is also true …
In general, as temperatures rise, the strength and performance of the plane drop. As the air heats up, it grows and becomes more dense, or thinner, as the air at higher altitude.
So on a hot summer day, a plane engine gets the lower air, with less oxygen. That makes less lift, and the plane needs to travel faster and farther to take off and fly, as it is at a higher altitude. The up side is, because the air is "expanded," you can use less fuel to get up.
Other benefits of flying in the winter
In cold, dry days, not only cooler, harder air contributes to better-performing airplane engines, but less convective heating means lower chaos.
Continual heating is the waves or thermals created when the heat from the large bodies of the earth emits heat in cooler air, creating bumps, known as chaos.
In more complex activities, the likelihood of typhoons is lower, so if the air is low, flights are usually clearer. Also, lower moisture improves visibility.
Another benefit of winter flight: fewer air traffic. That means less stress, and greater flight pleasure.
