“Nearly 50 flights out of Phoenix, Ariz. were cancelled Tuesday (20th June) thanks to scorching temperatures across the southwestern United States.”
“Temperature (Heat) related delays could cost airlines millions of dollars” a new study published by Earth Institute at Columbia University
According to FAA, 2.2 million passengers fly every day and all prefer to get to their destinations on time.
However, there are always delays and cancellation of airlines across all airports around the world.
Most delays are due to poor visibility, icing conditions and storms; but the new problem is “heat”.
A new study published today in the journal Climatic Change finds that increasing temperatures may cause more flight delays because some planes cannot take off. Other planes will have to make do with less cargo and fewer passengers, impacting prices and revenues.
Study published says “During the hottest parts of the day, 10 to 30 percent of fully loaded planes may have to remove some fuel, cargo or passengers, or else wait for cooler hours to fly…..As air warms, it spreads out, and its density declines. In thinner air, wings generate less lift as a plane races along a runway.
Thus, depending on aircraft model, runway length and other factors, at some point a packed plane may be unable to take off safely if the temperature gets too high. Weight must be dumped, or else the flight delayed or canceled.”
Also “heat waves will probably become more prevalent, with annual maximum daily temperatures at airports worldwide projected to go up 4 to 8 degrees C (7.2 to 14.4 F) by 2080…..It is these heat waves that may produce the most problems.”
The study suggests that if emissions continue on current trajectories payload weights and fuel capacities will have to be reduced by as much as 4 percent on the warmest days. Imagine what this means for some of the air cargo carriers from a business perspective. For airlines carrying people, a 4 percent reduction could mean 12 to 13 fewer passengers per plane – a big economic impact on already thin profit margins.
