New Delhi (PTI): As many as 338 A320 family aircraft operated by Indian airlines require the software upgrade to address a potential issue related to flight controls, and modifications have been carried out in more than half of the affected fleet, according to DGCA data.

Sources told PTI that there are no flight cancellations, but there are delays in the range of 60-90 minutes for some flights as the software updates are being carried out for the affected planes.

On Friday, Airbus said intense solar radiation might corrupt data critical to flight controls in a significant number of A320 family aircraft and that the software changes required to fix the issue would lead to operational disruptions.

The software upgrades have been completed for 189 A320 family planes out of the total 338 aircraft, as per the data available with the Directorate General of Civil Aviation (DGCA) till 10 am on November 29.

The software upgrades on all the affected planes are to be completed by 5:29 am on November 30.

DGCA on Saturday issued an Airworthiness Directive to airlines asking Indian operators to immediately carry out the requisite software upgrades.

This followed Airbus issuing an alert to operators globally and European Aviation Safety Authority (EASA) coming out with an Emergency Airworthiness Directive regarding the potential issue.

IndiGo, Air India and Air India Express operate A320 family planes, which include A320 ceos and neos, A321 ceos and neos. The affected aircraft need software upgrades or hardware realignment.

A total of 200 IndiGo planes have been affected, and software upgrades have been completed for 143 of them, while in the case of Air India, 113 aircraft have been impacted and upgrades have been done for 42 of them, the DGCA data showed.

In the case of Air India Express, 25 planes have been impacted, and the software upgrades have been completed for 4 of the aircraft, as per the data till 10 am.

The software upgrades are being undertaken at the bases of the airlines in Delhi, Bengaluru, Mumbai, Chennai, Hyderabad, Ahmedabad and Kolkata.

In a post on X at 10.13 am, Air India said that following EASA and Airbus directives for a mandatory software and hardware realignment on A320 family aircraft, our engineers have been working round-the-clock to complete the task at the earliest.

"We have already completed the reset on over 40 per cent of our aircraft that are impacted by this, and are confident of covering the entire fleet within the timeline prescribed by EASA," the airline said.

Air India also said there have been no cancellations due to this task, and there is no major impact on schedule integrity across its network.

"However, some of our flights may be slightly delayed or rescheduled," it added.

On Friday, EASA said Airbus asked airline operators to install a serviceable Elevator Aileron Computer (ELAC) in the impacted aircraft.

Generally, ELAC is for flight controls.

Airbus, on Friday, said an analysis of a recent event involving an A320 family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.

"Airbus has consequently identified a significant number of A320 Family aircraft currently in-service which may be impacted," it had said in a release.

Airbus had said it acknowledges these recommendations will lead to operational disruptions to passengers and customers.

New Delhi (PTI): India and Russia on Friday firmed up a five-year plan to bolster economic and trade partnership in the face of Washington's punitive tariff and sanctions regime even as Prime Minister Narendra Modi conveyed to President Vladimir Putin that the war in Ukraine must be brought to an end through dialogue.

Following their summit talks, Modi and Putin unitedly demonstrated their keenness to impart a fresh momentum to the trajectory of the over eight-decades-old partnership between the two nations.

Besides finalising the 2030 economic programme, the two sides signed several agreements to expand cooperation in a number of sectors including health, mobility and people-to-people exchange.

"Over the past eight decades, the world has witnessed numerous ups and downs. Humanity has had to pass through many challenges and crises. And amidst all this, the India-Russia friendship has remained steadfast like a pole star," Modi said in his media statement.

The prime minister, referring to the economic roadmap, said taking the India-Russia economic partnership to new heights is now a common priority for both sides. Modi also said that India and Russia are working towards early conclusion of a free trade agreement with Eurasian Economic Union.

The Ukraine conflict also figured prominently in the talks with Modi saying that India has advocated for peace in that country.

"We welcome all efforts being made for a peaceful and lasting resolution of this matter. India has always been ready to contribute its part and will remain so in the future," he said.

On threat of terrorism, Modi said India and Russia have long been standing shoulder-to-shoulder in the fight against the menace.

"Whether it is the terrorist attack in Pahalgam or the cowardly assault on the Crocus City Hall -” the root of all these incidents is the same," he said.

"India's unwavering belief is that terrorism is a direct assault on the values of humanity and that global unity against it is our greatest strength," he added.

Modi said India-Russia cooperation in the critical minerals sector is crucial for ensuring secure and diversified supply chains across the entire world.

We could also talk about cooperation in construction of small modular nuclear reactors and floating nuclear power plants, he said.

Russia, India and other like-minded nations are working towards a just and multipolar world.
