The global warming made it harder for aircraft to take off

A new study shows that rising Earth temperatures will make aircraft more difficult to take off, people will have to limit the number of passengers and luggage.

According to a study by a group of American scientists published in the Journal of Climate, the temperature rises to dilute the air, reducing the force of lifting the wings.

Large aircraft will be difficult to increase speed, so they will need a larger and longer runway distance to achieve the minimum takeoff speed in hotter weather than usual.

When the runway is not long enough, flights will have to reduce the load.

To estimate how much to reduce, researchers used the Boeing 737-800 in a 'simulated climate model' with summer temperatures at four key airports in the United States. They then compared the results found with different thermal thresholds that required aircraft load restrictions.

The results show that between the years 2050-2070 all four airports will have to increase the "day load limit year" compared to the present (an increase of about 50-200% per year).

Phoenix's airport will have to increase the number of days limiting the flight load by about 20 days. While other airports in New Yok, Washington DC and Denver now have several dozen days each year and may add a few dozen days in the future.

To balance, airlines will have to reduce the number of passengers or cargo unless the airline industry extends the runway or designs many aircraft with 'gravity gas' in accordance with the weather conditions when left. The soil gradually heated up.
