DGCA Grounds A320 Aircraft: Solar Radiation Glitch Alert November 2025

In a sweeping move that prioritizes safety over schedules, the Directorate General of Civil Aviation (DGCA) has issued an immediate directive affecting the workhorse of Indian skies: the Airbus A320 family. Following a rare and somewhat sci-fi-sounding warning from Airbus and the European Union Aviation Safety Agency (EASA), Indian carriers have been ordered to temporarily ground specific aircraft to fix a critical software vulnerability linked to solar radiation.

It wasn’t pilot error or mechanical failure. It was the sun.

Recognizing the severity of the risk, India’s aviation watchdog, the DGCA, didn’t wait. On November 29, 2025, they issued a mandatory directive: No affected aircraft flies until it is fixed.

The order impacts the Airbus A319, A320, and A321 models running a specific version of the ELAC software (standard L104). In India, this affects approximately 338 aircraft, primarily operated by IndiGo and the Air India Group (including Air India Express).

The directive is blunt: airlines must downgrade the software to a previous, stable version that is immune to this specific solar interference before the plane can take off again.

For Indian carriers, this is a logistical nightmare, but one they are tackling with impressive speed. The fix isn’t a weeks-long engine overhaul; it’s a software patch that takes about 30 to 40 minutes per plane. However, doing this for hundreds of aircraft simultaneously is a massive challenge.

While cancellations have been surprisingly minimal thanks to this rapid response, delays of 60 to 90 minutes have been reported as planes are pulled out of rotation for the update.

It is easy to get frustrated by a delay, but this event highlights the robustness of modern aviation safety. In the past, such a glitch might have gone undiagnosed until a tragedy occurred. Today, a single incident triggers a global safety net.

If you are flying on an Indigo or Air India Airbus this week, don’t panic, but do prepare:

Check Your Status: Before leaving for the airport, check your flight status on the airline’s app. The situation is fluid as planes are cleared for service.

Update Contact Details: Ensure your phone number and email are updated in your booking so the airline can contact you if there is a last-minute swap.

Be Patient: The delay you are experiencing is literally the time it takes to ensure your plane’s computer doesn’t get confused by the sun. It is a delay worth waiting for.

For now, the skies over India are getting safer, one software patch at a time. The A320 family remains one of the safest aircraft in history, and thanks to this quick intervention, it stays that way.
