Heat waves can pose a risk to air travel, affecting the performance of aircraft. High temperatures can lead to travel delays, weight restrictions, and even cancellations. The science behind this issue is related to aerodynamics, as planes rely on denser air to generate lift for takeoff.

Further information on how heat waves impact air travel is available from CNN, including insights from a professor at the Universidad Aeronáutica Embry-Riddle with experience as a pilot for United Airlines.
