New Delhi: Flight operations were affected at New Delhi’s Indira Gandhi International Airport (IGI) on Friday due to the severe heat — the temperature touched 44.9 degrees Celsius in Palam. Due to heatwave conditions, services were delayed in the afternoon for nearly three hours as authorities waited for the sun to lower.
A similar situation was reported from Phoenix in the United States of America in June last year when dozens of flights were canceled at the Phoenix Sky Harbor International airport for a few days after temperatures soared to around 48 degrees Celcius (118 degrees Fahrenheit).
But how do rising temperatures affect air services?
It is difficult for an aircraft to take off when there’s severe heat as the air becomes thinner. When the density reduces, there is lesser air to lift an aircraft off the ground. This puts additional pressure on the engine to generate more power during take-off. When temperatures rise, like they did in the capital city on Friday, planes require a longer runway length to take off.
Further, severe heat can also result in the overheating of an aircraft’s components.
