Planes Grounded Due to Record Heat Wave

Why Phoenix’s Airplanes Can’t Take Off in Extreme Heat

Phoenix just provided another reason to hate flying: the heat. With temperatures there expected to hit 119 degrees Fahrenheit, airlines canceled more than 40 flights today.

Wait. What? Airplanes can’t fly because it’s too hot? That’s crazy.

No, not really. According to news reports, the heat poses a particular problem for the Bombardier CRJ airliners, which have a maximum operating temperature of 118 degrees. Bigger planes from Airbus and Boeing can handle 126 degrees or so.

OK. But why?

Summary of the Great Southwest U.S. Heat Wave of 2017

The great Southwest U.S. heat wave of 2017 is gradually diminishing, but it has left behind hundreds of smashed heat records, including at least four all-time hottest temperature marks for major stations. According to wunderground weather historian Christopher C. Burt, this week’s event has been the most intense heat wave yet recorded to affect the Southwest so early in the summer, coming about a week earlier than the previous great June heat waves that have affected the Southwest, like those of 2013, 1990 and 1994.
