India to upgrade air traffic messaging system by 2026
The Airports Authority of India (AAI) is going to introduce a new system called AMHS by March 2026.
This system will help airports and airlines send important messages like flight plans and weather reports more reliably.
The old system had a problem last month that caused delays in almost 400 flights over two days.
The new AMHS system will connect over 80 airports in India and will follow international standards set by the International Civil Aviation Organisation (ICAO).
The AAI has also been told to check all their communication and navigation equipment to make sure they are working well.
This new system will make things faster and more efficient for everyone involved in air travel.
