More severe weather will affect commercial airplanes

I have been watching a series Mayday, on airline crashes in the past. One show focuses on severe weather. I was thinking, this would be an easy factor to see how we are being affected by climate change, how aviation is affected. Sure enough, they predict a lot of changes in how airplanes fly, because for instance with higher temperatures, you must lower the weight of the airplane.


A 2016 report from the International Civil Aviation Organization (ICAO), a UN agency, warned that higher temperatures caused by climate change could "have severe consequences for aircraft take-off performance”, including how many passengers and how much fuel airplanes are able to carry.

Global warming will also affect how airports are built. Changes in temperature and rainfall could “increase the demand for cooling for buildings or increase the drainage requirements for runways,” said the report.


As scientists focused on the impacts of climate change and extreme weather on human society and natural ecosystems around the world, our research has quantified how extreme heat associated with our warming climate may affect flights around the world. We’ve found that major airports from New York to Dubai to Bangkok will see more frequent takeoff weight restrictions in the coming decades due to increasingly common hot temperatures.

Here is a Mayday show on Cruel Skies

This special looked at the role of bad weather in aviation disasters and examines the US Aviation Weather Center in Kansas City, Missouri, to see how information on weather is transmitted to pilots in the sky.

1. Already happening.

There were planes grounded last summer because of excessive heat. This problem will spread until engines are redesigned to compensate.

2. A real issue in Aspen Colorado

Every pilot I know does an air density altitude check before taking off in the summer heat.
That includes all aircraft, private or commercial.
There is a little circular like slide rule. You put in the temperature and the altitude of the airport.

Altitude = less lift on wings
Temperature = density of the air = less lift on wings.

Maybe some pilot could tell us more about this topic?
