Severe cold wave sweeps Delhi, North; dense fog disrupts travel

Friday's was the coldest night of the season in Delhi. Early morning minimum temp was 3.9 deg C, three notches below the season's average and lowest in five years. Due to the 'very dense fog', visibility was zero at 5:30 am at the IGI airport. Fog would delay passenger arrivals at the airport but, with the ILS, flight ops were mostly normal Friday. Trains were running late.

By Sunday the mercury is expected to move up but not before it dips further: Punjab, Rajasthan may experience freezing point. The 'very dense fog' will stay until January 15. (The accompanying report was written by Artificial Intelligence)

NEW DELHI, Jan 12: Delhi experienced a severe cold wave on Friday, with the temperature dipping to a chilling 3.9 deg C in the wee hours. The city was also enveloped in a thick blanket of fog, reducing visibility significantly.

The day started with a dense fog that covered the city, causing a significant drop in temperature. The Indian Meteorological Department reported that the visibility at the Delhi airport was near zero in the early morning hours.

This dense fog is a common occurrence in Delhi during the winter months, particularly in January.

The cold wave conditions were severe, with the minimum temperature recorded at 3.9 deg C. This was a sharp drop from the previous day's minimum temperature of approximately 7 deg C. The maximum temperature for the previous day was less than 15 deg C, providing little respite from the cold.

The weather affected daily life and disrupted flight schedules. However, the use of advanced technology like the CAT III navigation system ensured the safety of air travel during these adverse conditions.

The foggy conditions triggered the activation of the CAT III navigation system at the Delhi airport. This system is designed to help planes land safely during dense fog and inclement weather conditions when visibility is low. It allows for landings with a minimum visibility of 50 metres. Despite this, the fog led to delays in several flights as some aircraft are not CAT III compliant.

Precautions for travel in fog: During dense fog, it's important to take certain precautions, especially if you're driving. Here are some expert suggestions:

  • Slow Down: Reduce your speed to ensure you have enough time to react if traffic slows or stops suddenly.
  • Use Low-Beam Headlights: Make your vehicle visible to others both ahead of you and behind you by using your low-beam headlights. This means your taillights will also be on.
  • Use Fog Lights: If your vehicle is equipped with fog lights, use them along with your low-beam headlights.
  • Avoid Abrupt Stops: Unless absolutely necessary, avoid making abrupt stops in the middle of the road.
  • Use Indicators: Always use your indicators when changing lanes or making turns to alert other drivers of your intentions.
  • Stay Updated: Keep track of the latest weather forecasts and take necessary precautions.

Remember, safety should always be your top priority. If the fog is too dense, it might be best to delay your trip until conditions improve. Stay safe!

What is CAT III: CAT III, or Category III, is an Instrument Landing System (ILS) used at airports, including Delhi's Indira Gandhi International Airport, to enable aircraft to land in low visibility conditions. This system is particularly useful during dense fog and inclement weather conditions when visibility is low.

The CAT III system at Delhi airport is a state-of-the-art anti-fog landing system known as CAT III B Instrument Landing System (ILS). It helps planes land with the aid of radio signals and sometimes high-intensity lighting arrays. The system allows for landings with a minimum visibility of 50 metres. CAT III B has an additional ability to stop itself after landing on the runway, compared to CAT A.

In the CAT II system, a pilot is guided by the signaling system till 100 feet above the ground, when the runway isn’t in sight. In CAT III-B, an aircraft can descend till 50 feet above the ground because of the advanced signaling system. Then the pilot would see the approach and touchdown zone-lighting system.

In category III B approach, the entire process is automated and a voice prompt tells using a countdown how far the plane is away from the runway, when the flaps have to be deployed and when the brakes need to be applied.

The initial cost of setting up the whole CAT III B system at an airport can go up to Rs 10 cr and the maintenance cost can go around Rs 50 lakh on a monthly basis.

CAT III B airports: The airports equipped with the CAT III B system to ensure the safety of air travel during adverse weather conditions in India are: Delhi's Indira Gandhi International Airport; Netaji Subhas Chandra Bose International Airport, Kolkata; Kempegowda International Airport, Bengaluru; Amritsar Airport.; Jaipur Airport; Lucknow Airport

CAT III is not airline-specific: It's important to note that the use of CAT III is not specific to any airline but rather depends on the equipped aircraft and the airport's facilities. Most modern commercial aircraft are equipped with CAT III ILS capabilities, and many airports around the world have CAT III ILS installed on at least one of their runways. Therefore, airlines operating these aircraft and flying to these airports would be able to use the CAT III system.

For safety reasons, aircraft must be certified and system-compliant and the pilots trained to use the CAT III systems.

Types of aircraft landing systems: There are several types of aircraft landing systems used around the world. Here are some of them: -

  • Instrument Landing System (ILS): This is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. It uses two directional radio signals, the localizer for horizontal guidance, and the glide slope for vertical guidance.
  • Microwave Landing System (MLS): This is a type of precision approach system that uses a set of radio signals to provide precise lateral and vertical guidance to an aircraft approaching and landing on a runway.
  • Joint Precision Approach and Landing System (JPALS): This is a differential, GPS-based precision landing system that guides aircraft onto a carrier deck or a land-based runway in all weather conditions.
  • Autoland: This is a system that fully automates the landing procedure of an aircraft's flight, with the flight crew supervising the process.
  • Transponder Landing System (TLS): This is an all-weather, aircraft-independent landing system that provides precision guidance for a variety of aircraft types.
  • Precision Approach Radar (PAR): This is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached.

Each of these systems has its own unique features and is used under different circumstances depending on the requirements of the aircraft and the airport.

His inaction amounts to defeating the rights of the people of the State to welfare measures sought to be implemented through the Bills, the Kerala Government's petition submitted, while the State of Tamil Nadu remarked that its "Governor is acting as a political rival."

Tailpiece: Coming up back to back, the petitions in their totality seem to question the provision of Raj Bhavan, and not motives of a Governor as a person.

Hundreds of cars piled up behind the wreckage of crashes occurring one after other in backing up - continuous crashes to the rhythm of metallic clanks and bangs back to back. According to reports, some ops required 'Jaws of Life' to pull apart the mangled cars to save lives inside.

Shocking news from the UK: Leading grocers have started bribing policemen with free food and drinks to persuade them to take action against shoplifters.

Shoplifting has risen by about 27 per cent in 10 major cities across the UK this year. The cost of retail crime last year was $2.15 billion. Besides, “We are seeing organised gangs threatening staff with weapons and emptying stores," Helen Dickinson, chief executive of the British Retail Consortium, said. Data shows that the police failed to respond to 73 per cent of serious retail crimes that included assault and abuse of workers, apart from shoplifting.

Isar Mohammad allegedly picked up a banana offered to Ganesh idol on Chaturthi at a makeshift temple in Delhi and consumed it.

Harris said hip-hop is “the ultimate American art form” that “shapes every aspect of American popular culture.” “Hip-hop culture is American culture,” she said in a talk at her official residence at the US Naval Observatory in Washington, D.C.

The social media had mixed reaction. There was much appreciation that she dances better than any VP in American history. But some called her "moves" as “cringe” while others did not like her pink pants - "pink pants don’t look good.” In fact, her ensembles have always been incongruous.

"Let’s see how the (Governor's) Vice-Chancellors are given salary." Mamata's extreme statements will put the Marxist Government in Kerala, which is also facing similar issues, to shame. Has she begun the countdown for a war on the streets?

It's true Mamata has come to see a conspiracy to demolish the established systems across the country, but lacks the ability to foresee what exactly is being pushed.

Brandishing a sword, Mahant Paramhans told reporters on Tuesday he himself will behead MK Stalin's son for his remarks against Sanatan Dharma in case nobody came forward to accept his offer he made in his video. Udhayanidhi reacted to the saint's Monday video, "I will speak more. I am the grandson of the artist who put his head on the rail track for Tamil Nadu."

Somanath elaborated, "I am an explorer. I explore the Moon. I explore the inner space. So it's a part of the journey of my life to explore both science and spirituality. So I visit many temples and I read many scriptures. So try to find the meaning of our existence and our journey in this cosmos. So it's a part of the culture that we are all built to explore, find out the inner self as well as outer self. So for the outer, I do science, for the inner I come to temples." (See videos)

Rao the mathematical legend had fathered the path-breaking Rao-Blackwell theorem, one of the most important theorems in mathematical statistics, at the age of 25. That brought him global fame. He is also famous for his Cramér-Rao Bound inequality theorem relating to quality of estimators in statistics which has had a profound bearing on applications of modern economics and several other diverse fields. Simply put, with the pioneering statistician computation became a tool to analyse even socio-economic challenges of modern times.

The alleged incident has received such a flash publicity that a standardised city's hugely middle class population will have second thoughts about eating outside for some time. Now everything on the table looks suspicious!

“All subjects directly connected to the people should be shifted to the State List. Particularly the subject of education. Only if this is done can cruel exams like NEET be abolished,” Stalin said. Education was moved from the State List to the Concurrent List with the 42nd Constitution Amendment made by the Central Government in 1976.

Decentralisation has been at the core of Tamil politics since the times of CN Annadurai. Stalin indicated there will be political changes in the offing.

TAILPIECE: While the Centre and the States are at loggerheads, it takes a different cognitive acumen to know that entrance tests are not the way for students' admission to courses.

Maruti is recalling 87,599 S-Presso and Eeco vehicles to inspect and possibly replace parts in the steering system. All reputed companies around the world do recall their products when a defect comes to light.

Meanwhile, a question arises why just in about a year so many accidents have taken place involving Mercedes sent to India while the car has won safety awards abroad? In most cases, the vehicle collided with divider, while manoeuvring a turn. Was there a split second delay in the steering system coming to a grip when at high speed? Did anybody in India bother to study a pattern in several of these accidents that took place one after other?

Former Tata Sons chairman Cyrus Mistry died when his Mercedes-Benz-SUV hit a divider in Gujarat. Cricketer Rishabh Pant's Mercedes-Benz-SUV rammed a divider in Uttarakhand and smashed. It went up in flames but he escaped with injuries. Brother of PM Narendra Modi, Prahlad Modi's Mercedes-Benz-SUV met with a similar accident in Mysuru. And many more.

  • Experts blame violation of the Visual Flying Rules (VFR) for most of the chopper crashes in the mountains as the leading cause. VFR means fly only visually - because of the lack of navigation aids in remote areas or unreliability of GPS-like aids in hilly terrains or a remote manipulation of instruments in cases of sabotage - as the topography plays havoc especially in the monsoon (mid-June to September).
  • Even when VFR is followed, most crashes occur due to CFIT (Controlled Flight into Terrain) - that is, everything else is OK but the aircraft collides with hills or trees hidden by the clouds. This also occurs mostly in the monsoon.
  • On Tueday with Manang, the chopper was brand new, pilot was highly experienced. But it hit an 'invisible' tree and then crashed against a hillside. This CFIT occurred when the pilot tried to dodge patches of clouds even as he was following the VFR.
  • Simply put, everyone knows flying in the hills during the monsoon is risky, but the companies want to make more money in any which case. This type of tragedy is very frequently invited in the Indian hill State of Uttarakhand as well, where pilots are even made to fly without the mandatory rest.
