What You'll Learn
How many planes can be stacked on the final approach?
The final approach is the last leg of an aircraft's landing approach when the aircraft is lined up with the runway and descending for landing. In terms of how many planes can be stacked on the final approach, it depends on various factors and there is no definitive or theoretical limit.
Air Traffic Control (ATC) is aware of how many planes are coming into an airport from departure to touchdown, and planes are stacked hundreds or even thousands of miles out. ATC separation rules dictate that the number of planes on an Instrument Landing System (ILS) approach depends on the type of aircraft. For instance, at busy airports like JFK and Atlanta, it is common to see four or more aircraft stacked one after the other on the final approach, with more on the way past the range of sight.
The approach slope, or glide path angle, is also a factor. Airports with steeper approach slopes, such as London City Airport with a 5.5-degree slope, require special approval and longer landing distances, which can reduce runway throughput. Heathrow and London Luton airports are trialling slightly steeper approaches to reduce noise by keeping aircraft higher for longer.
In summary, the number of planes that can be stacked on the final approach depends on factors such as aircraft type, ATC separation rules, and the approach slope of the runway. While there is no definitive limit, factors such as these will influence the number of planes that can safely be stacked during the final approach.

How airport capacity has changed over time
Airport capacity has changed significantly over time, influenced by various factors such as technological advancements, economic fluctuations, and shifts in passenger demand.
Historically, airport capacity expansions were driven by the need to accommodate increasing air traffic. The impact of these expansions, however, varied across airports, with some continuing to operate below their pre-expansion capacity due to factors such as recessions, changes in airline operations, and regulatory shifts.
The introduction of new aircraft technology played a pivotal role in enhancing airport capacity. For instance, the deployment of Boeing's 787 Dreamliner and Airbus's A350, which had lower operating costs and required less capacity than older wide-body aircraft, enabled airlines to initiate nonstop flights to additional destinations. This technological advancement expanded the reach of air travel and contributed to the overall growth in airport capacity.
Passenger demand for air service has a direct relationship with national economic output. As national gross domestic product (GDP) increases, passenger demand tends to follow suit. This correlation was evident in the long-term trend of increasing capacity and passenger traffic in the United States, with a significant rise in revenue passenger enplanements from 677 million in 2000 to 931 million in 2019.
However, airport capacity is not solely determined by passenger demand. The COVID-19 pandemic caused the most significant downturn in global aviation activity since World War II, with a drastic reduction in air traffic. During such unprecedented events, airport capacity adjustments become necessary to align with the decreased demand for air travel.
Additionally, the emergence of new airline business models, such as ultra-low-cost carriers (ULCCs), has influenced airport capacity dynamics. By catering to leisure travelers and expanding operations to previously underserved markets, ULCCs have contributed to the overall increase in airport capacity and passenger traffic.
In summary, airport capacity has evolved over time due to technological advancements, economic fluctuations, passenger demand, and the introduction of new business models. These factors collectively shape the landscape of air travel, driving the expansion and utilization of airport capacity to meet the evolving needs of passengers and the aviation industry.

How many passengers can a busy airport handle?
The number of passengers a busy airport can handle depends on several factors, including the airport's infrastructure, capacity, and efficiency, as well as the efficiency of air traffic control and the number of flights serviced.
A busy airport's passenger handling capacity is influenced by its infrastructure, including the number and size of terminals, gates, and runways. Larger airports with multiple terminals and efficient design can manage a higher volume of passengers. Additionally, efficient use of space and technology can enhance an airport's capacity.
The efficiency of airport operations also plays a crucial role. Well-organized processes, including check-in, security, and baggage handling, facilitate smoother passenger flow, enabling the airport to handle a larger number of travellers. Adequate staffing and efficient staff training further contribute to the airport's ability to manage a higher passenger volume.
Air traffic control (ATC) is another critical factor. ATC manages the sequencing and spacing of aircraft, both in the air and on the ground. Efficient ATC procedures can maximize the number of aircraft that can take off and land, directly impacting the number of passengers an airport can accommodate. However, as noted by pilots, ATC staffing shortages and delays can affect the overall efficiency and capacity.
According to the Federal Aviation Administration (FAA), their Air Traffic Organization (ATO) services more than 44,000 flights and over 3 million passengers daily across more than 29 million square miles of airspace. This provides a glimpse into the scale of operations and the number of passengers a busy aviation system can handle.
While it is challenging to provide an exact number for the passenger handling capacity of a busy airport due to the dynamic nature of aviation, Hartsfield–Jackson Atlanta International Airport in Georgia, consistently ranked as the world's busiest airport, can offer some insights. With its extensive infrastructure and efficient operations, Atlanta Airport has handled over 100 million passengers annually before the COVID-19 pandemic, showcasing the exceptional capacity of a leading global airport.
