What is too hot to land a plane?

The maximum temperature at which an airplane can take off and land depends on a number of factors, including the type of aircraft, the length of the runway, and the altitude of the airport. But, in general, most airplanes cannot take off or land in temperatures above 120 degrees Fahrenheit.

Air is less dense and generates less lift in extreme heat, making it harder for airplanes to take off, according to the FAA. In some cases, airlines must reduce the amount of cargo and/or passengers on the plane in order to take off in high-heat conditions.

Bombardier jets, for example, are designed to operate in temperatures of no more than 118 degrees Fahrenheit, whereas larger Airbus and Boeing jets are able to operate in temperatures of no more than about 126 degrees Fahrenheit.

When you land, you're aiming for a very specific point on the ground. Withour training, landing a small plane safely and smoothly first time is pretty much impossible. It's even harder in a big plane due to your height above the tarmac when about to touch down, plus the higher speed.

Even taking off and landing in heavy rain, snow, and fog is possible for aircraft equipped with adequate instruments and automated control systems for the conditions. However, heavy winds and thunderstorms, which often accompany rain, can keep aircraft grounded and result in airline flight cancellations.

Contrary to what many passengers believe, commercial airplanes can fly in almost all weather conditions and are rarely affected by lousy weather.

But icing aside, cold air can help a plane take off and fly more efficiently. So why do planes perform better in cold weather? Simply, colder air is denser than warmer air, which contributes to engine performance and air lift.
