Caution: Ethiopia's Volcanic Ash Engulfs Indian Skies, DGCA Urges Airlines to Redirect Flights

Post by : Samir Nasser

A significant volcanic eruption in Ethiopia has released ash clouds that have drifted into multiple countries, including India, raising important aviation safety concerns. The Directorate General of Civil Aviation (DGCA) in India has urgently advised all domestic airlines to stay clear of areas affected by volcanic ash to ensure the safety of passengers.

The eruption of the Hayli Gubbi volcano on November 23, 2025, after a staggering 10,000-year dormancy, sent thick columns of smoke and volcanic ash soaring up to 14 kilometers into the atmosphere. These ash clouds have traveled through Yemen, Oman, Pakistan, and have impacted northern, eastern, and northeastern regions of India. The ash is expected to linger in these areas in the following days.

Volcanic ash poses a significant threat to aviation safety due to its abrasive nature, which can severely damage aircraft engines, potentially resulting in failure. Additionally, the ash can affect various components of the aircraft and interfere with operational sensors, creating serious hazards during flights. To mitigate these risks, the DGCA is advising airlines to modify their flight routes, plans, and fuel estimates. Moreover, pilots must report any unusual symptoms such as engine anomalies, cabin smoke, or strange smells that could indicate an ash encounter.

The ash clouds have already disrupted some flights. For example, an IndiGo service from Kannur to Abu Dhabi was rerouted to Ahmedabad, while several other flights in affected regions have been canceled.

In response to the ash fallout, the DGCA has mandated that airlines perform comprehensive inspections of their engines and aircraft structure after flights operating near ash-affected zones. Some airports may temporarily cease operations or face delays if conditions worsen. Flight dispatchers are required to monitor volcanic ash advisories, satellite imagery, weather reports, and forecasts for ash dispersal to ensure updated communication.

Airports impacted by volcanic ash must also conduct inspections and clear runways, taxiways, and aprons before resuming standard operations. In cases of severe ash accumulation, airport activities could be limited or suspended indefinitely to avert accidents and further damage.

The DGCA's advisory echoes the guidelines set forth by the International Civil Aviation Organization (ICAO), reinforcing adherence to strict safety protocols and manufacturer recommendations to safeguard the aviation sector during such natural disturbances.

The incident underscores the urgent necessity for diligent coordination and communication among aviation authorities, airlines, and airports to navigate the dangers posed by volcanic eruptions and ensure safety for air travel in the impacted regions.
