What Happened?
On November 8, 2024, at approximately 5:45 AM, a technical glitch affected the Automatic Message Switching System (AMSS) at Delhi’s indira Gandhi International Airport (DEL). the AMSS is a critical component of the air traffic control system, responsible for processing flight plan messages. This disruption led to delays in flight planning and processing.
The Airports Authority of India (AAI) initially responded by deploying additional personnel to manually process flight plans, a substantially slower process than the automated system. According to the AAI, the Original equipment Manufacturer (OEM) was engaged to address the issue.
The AAI announced on Friday evening, November 8th, that the “technical issue in the AMSS, which caused delays in processing flight plan messages” had been addressed. However,backlogs persisted,causing continued,albeit reduced,delays.
Impact on Flights
The disruption impacted a considerable number of flights. According to Hindustan Times, more than 800 flights were delayed. Delhi’s Indira Gandhi International Airport is the busiest airport in India, handling a significant volume of domestic and international air traffic.
Delhi international Airport Limited (DIAL), the airport operator, confirmed on Saturday, November 9th, that airline operations had returned to normal.
| Date | Time of Disruption | Estimated Flights Affected |
|---|---|---|
| November 8, 2024 | Approximately 5:45 AM | 800+ |
Technical Details and Resolution
The issue was identified in the IP-based AMSS system on November 6, 2024, two days before the disruption. A joint team from the electronic Corporation of india Limited (ECIL) and AAI personnel remained on-site to monitor the system and address any lingering issues.
While the AMSS systems are now functional, the AAI acknowledged that some backlogs may cause minor delays in automated operations. They anticipate a full return to normal functioning shortly.
