Airlines to Save Around INR 150-180 Crore Annually by Using Delhi Airport's Eastern Cross Taxiway

Airlines are likely to save around INR 150-180 crore annually by using the Delhi airport's Eastern Cross Taxiways that help reduce taxiing time as well as fuel consumption by aircraft, according to a top official.

The Indira Gandhi International Airport (IGIA) in the national capital, operated by DIAL (Delhi International Airport Ltd), handles up to 1,500 aircraft movements daily.

In a recent interview, DIAL CEO Videh Kumar Jaipuriar said assuming 10-15% of aircraft use the Eastern Cross Taxiways (ECT), it is expected that there would be savings of around 55,000 tonnes of carbon dioxide. There can be savings of INR 150 to INR 180 crore for airlines by using the ECT, he said.

The ECT, which is 2.1 km long and can accommodate wide-body aircraft, will reduce the time spent on the tarmac by passengers after landing and before take-off of their flights. It was inaugurated on July 14. Delhi Airport became the first airport in India to have four operational runways. The 4th Runway also would help reduce Carbon emissions significantly.

Citing back-of-the-envelope calculations, Jaipuriar said DIAL has estimated how many aircraft will be using the ECT and how much travel time will be reduced.

"Each litre of ATF produces 2.5-3 kg of carbon dioxide. If we are talking about saving 55,000 tonnes of carbon dioxide, you divide it by 3 and that means around 18,000 tonnes of ATF." "Each tonne of ATF costs Rs 1 lakh and it is Rs 100 per litre… savings for airlines because of lower taxiing time is expected to be around INR 150-180 crore," he said.

On average, Jaipuriar said 7-8 minutes of taxiing time is saved for an aircraft that lands in the north and comes to the south through the ECT. As per DIAL, the ECT is estimated to save around 350 kg of fuel every time an aircraft taxis through the runway from RW 29R to Terminal 1 and vice-versa.

"This translates into a reduction of nearly 1,114 kilograms of CO2 emissions for each aircraft taxiing along this route. On an annual basis, the ECT is estimated to reduce emissions of approximately 55,000 tonnes of CO2 from aircraft," it said in July this year.

DIAL had also said 55,000 tonnes of CO2 emission is equivalent to planting about 15 lakh trees.

The ECT connects the northern and southern airfields on the eastern side of the airport and will reduce the taxiing distance for an aircraft by 7 kilometres. The distance an aircraft needs to cover after landing on the third runway and going to Terminal 1 (T1) will be reduced to 2 kilometres from 9 kilometres now.

The dual-lane ECT can handle wide-body aircraft, including A380, B777 and B747. Each lane is 44 metres wide with a gap of 47 metres between them to allow simultaneous passage of two aircraft.

Busiest Airport in India

Civil Aviation Minister Jyotiraditya Scindia stated earlier that IGIA can soon become the world's largest airport with the ongoing expansion of the airport. It can even surpass Atlanta Airport in terms of passenger capacity and become one of the world's biggest airports.

"The Delhi airport caters to 70 million passengers, which will likely go to 109 million by the end of this year. It is the only Indian airport with three runways, and the fourth one will likely become operational in September," Scindia added.

DIAL (Delhi International Airport Limited), a joint venture majority-owned by the GMR Group, had in 2019 announced an investment of INR 9,800 crore to upgrade the existing Terminal 1, build a fourth runway and for other development works to increase the airport's capacity to 100 million passengers a year from 66 million now.

In 2016, Delhi Airport ranked 9th among the world's ten busiest airports, as it handles 5.9 crore people annually. Meanwhile, the IGI Airport was recently named among the world’s 10 busiest airports by passengers handled. As per the Airports Council International (ACI), Delhi Airport ranked at the ninth spot for 2022, ahead of Paris’s Charles de Gaulle Airport. The Delhi airport is India’s largest and is the only airport from South and Southeast Asia to feature in ACI’s list of the 10 busiest airports. As per ACI data, the Delhi airport handled almost 5.95 crore passengers in 2022. The airport was ranked as the 13th busiest for 2021 and 17th busiest for 2019.

The Directorate General of Civil Aviation (DGCA) plans to come out with a framework early next year on what could be done to address gender issues, a top official said on Saturday, December 9. Speaking at an event in New Delhi, DGCA chief Vikram Dev Dutt said the issue of gender has been debated at the regulator informally.

"Systemically, when we as a regulator when we look within it... we thought we would show the mirror to ourselves as an organisation... early next year... we will come out with a framework for DGCA in terms of what we would do for gender, beyond paper and official circulars," he said. Specific details about the proposed framework could not be immediately ascertained.

Dutt also mentioned DGCA's larger role in influencing positive change within the private sector and sought stakeholder suggestions. Minister of State for Civil Aviation V K Singh said the tremendous growth story in Indian aviation is synonymous with the vision, inspiration, and strength embodied by women in this field. Women are incredible force multipliers, shaping the ever-expanding horizons of our aviation landscape.

Air travel is a complex symphony of engineering marvels, and one often-overlooked contributor to the seamless operation of an aircraft is the Auxiliary Power Unit (APU). As passengers board an aircraft, especially through the rear door on the tarmac, they may be greeted by the unmistakable sound of an engine running in the tail section. This sound emanates from the APU, a small but crucial gas turbine engine designed to provide electrical power and high-pressure air in various scenarios.

What is an APU?

The APU, or Auxiliary Power Unit, is a self-contained gas turbine engine typically located in the tail section of an aircraft. Despite its small size, the APU plays a pivotal role in ensuring the functionality of critical systems when the main engines are not in operation. This includes providing electrical power for lighting, emergency hydraulics, climate control, and even starting the main engines. The APU is structurally similar to a regular jet engine but lacks the external cowling. Its intake and exhaust are strategically positioned to optimize functionality.

APU Operations

The APU operates autonomously, initiated by a simple switch command from the pilot. It can start automatically, taking approximately 2 minutes, and can function up to the maximum certified altitude of the aircraft. Fuel for the APU is drawn from the aircraft's main tanks, consuming around 15 gallons or 60 kg per hour. An Electronic Control Unit (ECU) oversees APU operations, ensuring safety by monitoring various parameters such as overspeed conditions, oil pressure, temperature, and potential system faults.

Multiple Functions

The APU serves a multifaceted purpose beyond generating electrical power. It doubles as an air conditioner by providing cooled air to the aircraft's climate control system. While some may speculate about additional thrust, the APU, unfortunately, cannot contribute thrust to propel the aircraft forward. Its significance becomes apparent during ground operations, such as temporary airport closures, where the APU sustains essential systems, keeping passengers comfortable during unforeseen delays.

Cabin Pressurization

One of the critical roles of the APU is maintaining cabin pressurization. By supplying bleed air to the aircraft's systems, including the air conditioning packs, the APU ensures that the cabin pressure remains at a level conducive to human comfort and safety. This becomes especially important during takeoff, where the APU can assist in powering the air conditioning packs to enhance engine performance.

Main Engine Starting

The APU plays a pivotal role in initiating the main engines without relying on external ground equipment. It provides the necessary electrical power and high-pressure air for engine starting, eliminating the need for complex ground infrastructure. This proves particularly beneficial in remote airports where comprehensive ground handling facilities may be lacking.

Emergencies and Redundancy

In emergency situations, the APU becomes a lifeline for the aircraft. It serves as an alternate power source during electrical failures, and in the event of a double-engine failure, it becomes crucial for both electrical power and air conditioning/pressurization. The APU's contribution extends to hydraulic systems, where it provides power to emergency hydraulic pumps in case of a hydraulic failure.

Do All Airplanes Have An APU?

While APUs are commonly found in large airplanes, helicopters, and business jets, they are not mandatory for an aircraft to depart. Smaller aircraft often rely on alternate means for engine starting and electrical power. Despite its non-mandatory status, a non-functional APU can pose operational challenges, leading to increased workload and potential delays.

Conclusion

In the intricate dance of aviation technology, the Auxiliary Power Unit emerges as a silent hero, ensuring the seamless functioning of an aircraft's critical systems. From providing electrical power and air conditioning to facilitating engine starts and serving as a contingency in emergencies, the APU's significance cannot be overstated. As technology continues to evolve, the role of the APU remains integral to the safety and efficiency of air travel.
