Mumbai crowned world’s busiest single-runway airport with 1 flight in 65 seconds

Mumbai: The GVK group-run Mumbai airport has become the world’s busiest amongst the single-runway facilities by handling 837 flights a day or one in 65 seconds on an average in fiscal 2017, taking over London’s Gatwick airport that had 757 flights a day.

In terms of the number of passengers also, the city airport tops with 45.2 million people flying in and out in fiscal 2017 as against 44 million at Gatwick airport. Notably, no other large city in the world is served by one airport, that too with a single-runway.

Besides, illegal squatters occupy nearly one-third of the airport land. The second airport proposed in Navi Mumbai is yet to come up. All the leading cities like New York, London, Dubai, and Singapore have more than one airports with multiple runways. The New Delhi airport has three parallel runways in use at any given time. As against this, Mumbai has to make do with a single runway (09/27) for all passenger and cargo aircraft and when it is shut for repairs, it uses the secondary runway (1432).

In terms of aircraft movement in a day, the city airport had one plane take-off or landing in 65 seconds, which means it handled on an average 48 flights, peaking at even 52 movements at times, making it the busiest in the world on both the counts, an airport spokesperson said.

The ATC (air traffic controller) thus has to manage two arrivals every 130 seconds and one departure in between these two arrivals. So there is one take-off or touch-down every 65 seconds from the main runway. That means the land-starved airport handled a whopping 837 flight movements a day, which on an average is 80 flights more than Gatwick handling 757 movements in a day, the spokesperson said. There are days when the number crosses even 900 movements a day, she said.

However, the Delhi airport handles much larger number of passengers. At 45.2 million, Mumbai handled only 18.6 per cent of the total air traffic in the country while the Delhi airport handled 57.7 million passengers or 21.6 per cent of the total air traffic in the country in fiscal 2017. Out of the 45.2 million passengers at the Mumbai airport, 12.4 million were international travellers.

The airport’s originally envisaged capacity is only 40 million passengers. Mumbai currently has an extensive network that takes passengers to over 95 domestic and international destinations. In fiscal 2017, the city airport logged in an 8 per cent growth in volume over fiscal 2016. When the GVK group took over the operations of the airport in fiscal 2006, it handled just 18 million passengers.

By handling 44 million passengers, Gatwick airport in the British capital was delegated to be the world’s second busiest airport with single-runway operations, a position it held for many years. However, it lost the position to Mumbai in fiscal 2017 which handled 45.2 million passengers between April 2016 and March 2017, the airport spokesperson said. “From around 453 aircraft movements a day in 2006, we have grown to handle over 800 movements daily, handling over 45.2 million last financial year.

In terms of cargo shipments, we have grown from 5,32,000 tonne in fiscal 2008 to 78,29,000 tonne in fiscal 2017,” she said. Recently, the city airport welcomed two Airbus A350-900 that resulted in it becoming the only airport in the country to handle daily operations of two of the world’s most advanced premium passenger aircraft, the spokesperson said.

“To augment operational efficiency, we are expediting a host of projects and initiatives including constructing rapid exit taxiways, widening runways and taxiways and improving airspace management, helping us seamlessly accommodate an increasing traffic,” she said.

“Currently, work is on to connect the taxiway to runway 27 which can provide the much-required additional holding area for aircraft ready to take off on the main runway,” the spokesperson added.

This strategic move is in response to the anticipated surge in demand for wide-body freighter aircraft capable of long-haul flights.

Furthermore, South Korea’s forward-looking vision extends beyond aircraft conversion, with plans to establish a Lockheed Martin F-35 maintenance, repair, and overhaul depot at Cheongju Air Base by 2027. This strategic move not only enhances the operational readiness of South Korea’s air force but also positions the nation as a regional hub for F-35 maintenance expertise.

In preparation for this expansion, thirty Republic of Korea Air Force (ROKAF) engineers and technicians are slated to undergo intensive maintenance training in the United States in 2025, a testament to South Korea’s commitment to fostering local expertise and talent.

IAI’s visionary approach to certification and collaboration underscores the potential for transformative change. With plans for the 777-300ERSF certification process set to unfold in Israel, followed by the rigorous scrutiny of regulatory agencies such as the US Federal Aviation Administration (FAA), the stage is set for the ‘Big Twin’ to soar to new heights of success.

In partnership with esteemed entities like STK and Incheon International Airport Corporation, this collaboration promises to unleash a wave of benefits, amplifying the resilience and competitiveness of the Korean aviation sector while catalyzing job creation and economic prosperity.

Can Airline Seat Cushions Be Used As Life Jackets?

In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.

While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.

While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.

What fabric is used in aircraft seats?

Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.

Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.

What is the lightest economy seat?

In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.

According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.

For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
