Explained: How heatwaves disrupt flight operations and may cause mid-air turbulence
Delhi to Bagdogra was delayed due to high ground temperatures, which affected flight operations at Indira Gandhi International Airport in Delhi. This has resulted in delays as safety guidelines are followed, sometimes requiring flights to wait for wind speeds to stabilize.
A senior official from the Ministry of Civil Aviation told ANI that that high temperatures cause the air to become thin, impacting the lift required for aircraft to take off, especially during takeoff and initial climb. This can also cause mid-air turbulence for passengers. In extreme weather conditions like high temperatures and high winds, aircraft only proceed after getting clearance from Air Traffic Control (ATC).
To mitigate the effects of high temperatures, airlines may adjust operations by reducing fuel or baggage, and in some cases, even offloading passengers.
Frequent complaints about air conditioning not functioning in aircraft are also linked to high outside temperatures. A senior official from a domestic airline told ANI that the air conditioning systems struggle to cool the aircraft on short-distance flights when temperatures are extremely high. This issue can be particularly uncomfortable for passengers during taxiing and idling on the runway as cabin temperatures rise.
The national capital is dealing with severe heatwaves, leading to water shortages in several areas. The India Meteorological Department (IMD) has indicated that these heatwave conditions are expected to continue over many parts of North India, with some relief
