What is the coldest temperature a plane can takeoff in?

As long as the inside of the aircraft is kept warm enough, planes can take off and land in temperatures as low as minus 67 degrees Fahrenheit. It's often not much warmer than that outside your window at altitude. If you've ever put your hand on the wall or window when you're flying, you'll note that it's cold, sure.

The cold really doesn't hurt the airplane. Airliners fly at 30 to 45000 feet in -45/50 degrees F all the time. The higher you go the colder it gets. The SR71 can go up to around 100000 feet and it flies there at about -100 degrees F.

Since planes are designed to fly in this temperature, cold weather on the ground does not, by itself, inhibit flight. However, cold weather can impact activities on the ground. While less of an issue for take-off, an icy or wet ground can extremely inhibit a plane's ability for landing safely.

Heavy snow or blizzards can make landing and taking off too dangerous, while lightning storms can be very hazardous to any aircraft. Extreme heat can also interfere with an aircraft's performance, so in hotter parts of the world, extreme temperatures can cause significant delays.

Generally airline and passenger/freight carrying operations are suspended during periods of freezing rain. Even without being prohibited by the operators manual, operations in freezing rain are difficult as the applicable Hold-Over Time from an anti-icing treatment is very limiting in freezing rain.

This holds true up to 36,000 feet msl. So, while your standard temperature at msl is 15° C or 59° F, your standard temperature at 20,000 feet msl will be -24.6°C or -12.3°F.

When a plane flies through a supercooled cloud the disturbance causes droplets to collect on the airplane, and since the water droplets are already supercooled they solidify into ice almost instantly. While flying through a large cloud of supercooled water droplets, an airplane can experience considerable ice buildup.

Since cold air is denser than warm air, engines provide more power because there are more oxygen molecules. Similarly, “dense air makes the wings more efficient as there are more air molecules flowing over the wings, which improves takeoff and climb performance in cold weather,” says Haines.

Summer is the busiest travel season throughout the U.S., and weekends see the most airport traffic. Expect the biggest crowds and highest airline fares on Fridays in June, July, and August.

With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing.

Nothing SHOULD happen, and it happens occasionally but usually with no damage. When lightning strikes an airplane, the current flows through the conductive exterior of the aircraft and exits through another conductive point, such as the tail or wingtip.

MORE DETAILS

There is no single maximum wind speed that cancels flights, as it depends on the direction of wind and phase of flight. A crosswind above about 40mph and a tailwind above 10mph can start to cause problems and stop commercial jets from taking off and landing.
