On Wednesday, the last day of the year 2025, the capital Delhi was seen in the grip of dense fog. Due to the dense fog, flight operations at Indira Gandhi International Airport were badly affected, where a total of more than 300 flights were affected due to very low visibility since morning. As per available information, 148 flights were cancelled, which included 78 arrivals and 70 departures, while around 200 flights were delayed and 2 flights had to be diverted.

Airlines issued travel advisory

Many airlines including IndiGo, Air India and SpiceJet have issued travel advisories for passengers. Airlines have appealed to passengers to check the latest status of their flights before going to the airport. Delhi’s IGI Airport said that due to dense fog, flights are being operated under CAT III protocol, due to which there is a possibility of delay or cancellation.

The airport said, ‘Our ground teams are present on the spot and are helping the passengers. For latest information, passengers should contact their respective airlines. We apologize for the inconvenience.

Railway services also affected, passengers worried at stations
The effect of fog was also seen on railway services. Trains ran late on many routes, due to which the crowd and waiting of passengers increased at the railway stations of the capital. The speed of trains remained slow due to poor visibility.

Delhi’s air is also very bad
Along with fog, there was no improvement in the air quality of Delhi either. According to the Central Pollution Control Board (CPCB)’s Sameer app, Delhi’s average air quality index (AQI) was recorded at 383 at 6:05 am on Wednesday, which is in the ‘very poor’ category and has reached the ‘severe’ level.

Travelers advised to be cautious
The administration and airlines have appealed to the passengers to check the flight and train status before leaving home and take extra time to plan their journey, so that inconvenience caused due to fog can be avoided.

Flight Delays: The effect of winter has increased significantly across the country and along with it dense fog, severe cold and low visibility have also come. The Meteorological Department has warned that the same conditions are likely to persist for the next few days. Flights are being delayed, canceled and even rescheduled. Let us know where air travel has slowed down.

Delhi was most affected

Most problems are being seen at Indira Gandhi International Airport. On December 21, due to dense fog and low visibility, about 110 flights were canceled and more than 370 flights were delayed. Along with this, the same situation remained on 22 December also. More than 150 flights were late in the morning.

Impact outside the capital also

This problem was not limited to Delhi only. Flights to and from Amritsar, Bengaluru, Hyderabad, Srinagar and Chennai were also affected due to bad weather. Let us tell you that the effect of fog is more severe in the northern areas, whereas in the southern cities, there are delays due to delay in aircraft rotation and congestion at major hubs.

Flights stopped in Srinagar due to snowfall

Due to bad weather and snowfall at Srinagar Airport, many flights were canceled directly. Mountainous weather conditions and low visibility sometimes make operations unsafe. This is the reason why airlines have to temporarily suspend services.

Meanwhile, Indigo has also canceled flights on many routes. Airlines also issued a travel advisory urging passengers to check real-time flight status before going to the airport. Along with this, Air India has also started its seasonal fog care initiative. Under this policy, passengers affected by fog related problems can reschedule or cancel their flights without any extra fees.

advice for travelers

Passengers are being advised to check flight status before leaving home, reach the airport on time and also keep in mind road delays due to fog.

There was chaos at Indira Gandhi International Airport (IGI Airport) in the country’s capital Delhi on Friday (November 7) when a sudden technical glitch in the air navigation system affected the operations of the entire airport. Due to this disturbance at IGI, which is counted among the busiest airports in the world, about 800 flights were delayed and thousands of passengers had to wait at the terminal for hours.

According to sources, this technical flaw in the Air Traffic Control (ATC) system was so serious that both flight landing and takeoff were affected for some time. Many planes were kept in holding patterns in the air, while some had to be diverted to nearby airports. The problem was resolved at around 9 pm, after which flight movements gradually started becoming normal. It is a matter of relief that there was no major accident with any aircraft.

Passengers expressed displeasure

Expressing their displeasure, the passengers said that they were not informed about the situation for several hours. At the same time, passengers of many domestic and international flights were stopped at the gate as runway operations were temporarily stopped.

Where did the problem come from?

The Airport Authority and DGCA immediately deployed technical teams to handle the situation. The failure was related to the navigation data server, causing disruption in communications and navigation systems. During this time the airport staff tried to solve the problems of the passengers.

Advisory issued at around 11:55 pm

In an advisory issued at around 11:55 pm, Delhi Airport Management said, “All flight operations have now become normal. Passengers can travel without any worries.”

Flight operations were severely affected on Friday after a major technical glitch in the AMSS system at Delhi’s Indira Gandhi International Airport, due to which more than 200 flights were delayed. Earlier it was told that this has affected Mumbai Airport also, however later Mumbai Airport Authority said that advisory was issued to the passengers by mistake.

AMSS failed at Delhi airport

As soon as the AMSS system crashed at Delhi Airport, the air traffic control had to leave the automatic mode and work manually. Due to this, the data of each flight had to be processed manually. Distance calculations of the planes also had to be done manually and coordination had to be done through voice communication, due to which the operation of flights became much slower than usual.

Delay of more than an hour at Delhi airport

At present, there is an average delay of 62 minutes i.e. more than an hour in the departure of flights at Delhi Airport. According to data from Flightradar24, this delay has increased after a technical glitch in the air traffic control system. Airports Authority of India (AAI) has said that its teams are busy fixing the AMSS (Automatic Message Switching System), which supports ATC data. There are approximately 1,500 flight movements daily at Delhi Airport. Under normal conditions, 60-70 flights take off and land per hour. In such a situation, due to automation failure, the backlog of flights increased rapidly and the delay extended for several hours, the effect of which was seen in the entire network.

Mumbai Airport issued clarification

Mumbai Airport (MIAL) said that the advisory issued earlier was issued by mistake and was a human error. The airport clarified that all flight operations here are running completely normal and smoothly.

What is AMSS system?

AMSS is the system that sends flight plans, weather information, and other technical data between ATC and airlines. Once it fails, controllers have to enter all the data manually, which makes operations extremely slow and significantly affects flight time.

AAI issued advisory

Airport Authority of India issued a statement saying that due to AMSS malfunction at Delhi Airport, flight operations are getting delayed and the controllers are processing all the plans manually. Technical teams are continuously working on restoring the system. Passengers have been advised to stay in touch with their airlines and keep checking updated schedules.

Advisory issued for the convenience of passengers

Authorities have requested passengers to keep checking flight information from their respective airlines, be prepared for possible delays and follow instructions given at the airport. The situation is being monitored in both Delhi and Mumbai so that the system can be normalized as soon as possible.

A tragic incident took place on October 16 in United Airlines flight UA1093 going from Denver, America to Los Angeles. The Boeing 737 Max 8 aircraft was flying at an altitude of 36,000 feet when the front windshield suddenly broke. A pilot was injured in this incident.

There were a total of 140 passengers and crew members on board the plane. After the windshield broke the plane fell 10 thousand feet. After this, the pilots immediately adopted emergency procedures and brought the plane down and made a safe landing at Salt Lake City Airport. The passengers were later sent to Los Angeles in a Boeing 737 Max 9. No passengers were injured in this incident, but the flight arrived late by about 6 hours.

Pictures surfaced online after the incident

Pictures that surfaced online after the incident showed burn marks on the broken glass and injury marks on the hand of the injured pilot. The plane was about 322 kilometers southeast of Salt Lake City when the crew reported a windshield shattering. Aviation experts believe that the cause of glass breakage could be a collision with space debris or a small meteorite. Generally, the windshield of airplanes can withstand bird strikes or high pressure, but an object hitting it at very high speed can damage it.

United Airlines gave this information

United Airlines said the pilot suffered minor injuries and all passengers are safe. However, the real reason for the crack has not been known yet and the company has not given any official statement on this. This incident is considered serious for the airline industry as windshield breakage is extremely rare. Experts say that such incidents can be dangerous for both passengers and pilots.

Earlier on October 18, a United Airlines plane accidentally collided with the tail of another plane at Chicago’s O’Hare Airport. However, no one was injured in this too and all 113 passengers were evacuated safely.
