Dear MEL Topic Readers,
Why high temperatures can make planes too heavy to take off
As global warming heats airports, airplanes need longer runways or lighter payloads to take off. In some cases, some of the passengers were forced to give up their flights, or flights were canceled altogether when the temperature went too high for takeoff. In fact, a study found that the maximum takeoff weight at 10 airports in Greece has been reduced by 127 kilograms each year since the 1970s because of the rise in temperatures. That’s because aircraft get 1% less lift with every 3 degrees of temperature rise. For example, if an airplane needs a 2,000-meter runway for takeoff at 20 degrees Celsius, it’ll require 2,500 meters at 40 degrees. This difference in temperature is just like the one in the morning and the one in a sizzling afternoon at the same airport. Why does the temperature matter so much for aircraft to take off? How are airlines dealing with the rising temperatures?
