Understanding Air Transport Systems 
Airline and airport operations systems and their role in facilitating the movement of passengers and goods by air.

The role of airlines engaged in airports is to facilitate the movement of passengers and goods by air by executing the airline's schedules. Airline and airport systems handle everything from checking passengers to ensuring the aircraft is safe and ready to take off.

Landside airlines perform several essential tasks to prepare passengers for their flights; when passengers check in to drop off bags, they are processed in the background along with other services such as catering, security, and cleaning. All this happens in the background while passengers wait to board and transit from landside to airside. (Cheng-Lung, 2016,p. 7)

Once past security and boarding gates, airside operations get underway. The main focus is on a safe and efficient turnaround as quickly as possible. This includes boarding and onboarding passengers, cleaning the cabins, crew swaps, maintenance checks, refuelling, cargo handling, catering, and special needs. The main goal is to prepare the aircraft for its next flight quickly while maintaining safety and comfort. (Cheng-Lung, 2016,p. 7)

Some airlines conduct their own ground handling in their respective hub airports, while others opt to subcontract them to other ground handling companies at smaller airports to save on costs. This enables airlines to operate without investing in much ground handling equipment and services at smaller airports. (Cheng-Lung, 2016, 7)

These systems combine to ensure that passengers and cargo can be reliably and conveniently transported from A to B.

Components of Operations Systems

Air traffic control: 

Air traffic control, commonly referred to as (ATC)is one of the most critical components of airline and airport operations. “The Air Traffic Controller (ATCo) is responsible for monitoring aircraft movement within specified airspace by using radar and/or procedural control as its monitoring instrument” Rahman, Halim, and Sidik, (2019, p. 1).
They facilitate aircraft's safe and efficient movement on the ground and within the airspace.ATC is responsible for monitoring and instructing aircraft from push-back through take-off and navigating the aircraft's safe movements. They use various state-of-the-art technology, such as radar/satellite communications and navigation systems. UK Civil Aviation Authority (Nd)

ATC’s primary focus is to prevent accidents and manage traffic flow efficiently.

Ground Handling


Ground handling involves all services required to turn an aircraft around for its next flight while it’s on the ground. These services include baggage handling, cargo loading, ramp handling, refuelling, catering, and maintenance checks. 
The key to a company’s reliable flight schedule depends heavily on having efficient ground handling operations with minimal turnaround times. Rahman, Halim, and Sidik ( 2019).§

High standards in ground handling enable airlines to use their resources more efficiently, contributing to their overall operational reliability. At major airports, airlines have their own ground handling employees. However, small airports might opt for third-party ground handlers to save on cost.


Integration and coordination: 



Integration and coordination of systems Play an important role in ensuring the safety and efficiency of airline and airport operations. (FAA,2016)

The interconnectedness of ATC and ground handling means that one cannot operate safely without the other. Receiving real-time data from ground handling is paramount to ATC's management of aircraft movements and departures. Symbiotically, ground handling also relies on air traffic control for instructions such as refuelling, time frames, departure times, and pushback. Ashford et al., (2011)

Clear and concise communication and coordination between these two systems help prevent delays and maximise security and resource management. Integrated communication channels that can share real-time data and make live adjustments to changing weather patterns and delays further improve efficiency. Ashford et al., (2011)

This coordination ensures that aircraft turnarounds are conducted efficiently while maintaining safety, greatly helping airlines maintain operational reliability. 






Transport Infrastructure and Planning Process

Transport infrastructure and planning processes are fundamental in shaping an airline and how its operations are run, and how effective they can be. The Planning process for airports will encompass various separate elements such as airport layout, passenger terminals, cargo terminals, runway layout, and any other supporting infrastructure.
Each of these steps is hugely important in ensuring that an airport can handle the passenger and cargo demand it targets while maintaining safety and efficiency.
Transporting planning is shaping our environments, and it is important to consider both the infrastructure’s short-term traffic issues and the long-term goals. Effective interdisciplinary collaboration is the key to achieving sustainable outcomes from infrastructure development. (Bruton, 2021, P 51)


Passenger Terminals:

“Airport passenger terminals constitute one of the principal elements of infrastructure at the airport.” (Ashford, Mumayiz and Wright, 2011, 10.1 Function of Airport Passenger Terminal section)
Terminals have become architectural monuments for countries to present themselves. 
When designing a terminal, it is important to consider its functional design rather than just the architectural design. According to (Ashford, Mumayiz and Wright, 2011), a passenger terminal performs their main functions: change of mode, processing, and change of movement type.

Change of mode: Few air trips are made directly as air trips are connected to mixed-mode transport with surface access linking to the air. When designing a terminal, it is important to consider the movements of passengers to and from the airport.

Processing: Passenger terminals are where processes such as ticketing check-in and baggage drop-off are performed. Therefore, when designing a terminal, it is important to have ample dedicated space for passenger processing.


Runway and taxiways

 “The runway is a linear strip of land used for aircraft take-off and landing>”( (Teodorovic and Teodorovic, 2015, P 259). The design and connectivity between runways and taxiways are crucial for lowering taxi time and keeping a good traffic flow at the apron. The key to improving airport movement efficiency is parallel runways, rapid taxiways, and clear and visible signage.(FAA,2016)






When designing a runway, it is important to consider these crucial elements:

1.	Supports the weight of the aircraft without rapid deterioration.
2.	Sufficient drainage to prevent water build-up. 
3.	Sufficient length for the type of aircraft to take off and land safely.
4.	Sufficient width for lateral directions when taking off and landing.
5.	Free of hazardous obstacles.
6.	Enough visual guidance for the pilots during low visibility.
7.	Minimal crosswinds. (Teodorovic and Teodorovic, 2015, 259)



All these requirements are subject to the aircraft and its characteristics, such as size, width, payload, and performance. Therefore, choosing the right aircraft can be vital for a runway design as it will determine the markets and traffic forecasts, which have to be done before construction. (Teodorovic and Teodorovic, 2015, 259)



















Discuss strategies for optimising operational utilisation of Aircraft and Gates.


To achieve maximum profitability for an airline with efficient and minimal costs, aircraft and gate operational utilisation and optimisation play a crucial role. We will outline some of the challenges and key strategies for this optimisation.



Optimal turnaround
The widespread approach to aircraft Turnaround operations is to apply Standard operating procedures(SOPs). The SOPs are first outlined by the aircraft manufacturer, and airlines can customise them depending on their business model to suit their own agendas. (Cheng-Lung, 2016, P88)

The SOPs vary across different aircraft families depending on their design and capacity. Time frame/ Gant charts are the most common illustrations of SOPs.

 
Figure 2 B737 SOP for short-haul turnaround operations.
SOPs align all duties to the departure time, and each task has a specific due date. This prevents delays from piling up.
On the other hand, it is important to consider the interconnectivity of all these processes that aren’t explicit in the chart, such as all tasks being done in chorus. As an example, 23 minutes before departure, refuelling, cargo handling, cleaning and checks are all being done at the same time. Cheng-Lung, (2016, P 88).

Because these activities are done simultaneously, they can be grouped into processes and categorised into different units, such as baggage handling, catering, and cleaning. 
This is known as the Unit strategy and offers various cost and efficiency benefits to carriers who adopt them at their hub airports. Cheng-Lung, (2016, P 88).




Efficient Scheduling:

The optimisation of flight schedules is essential for any airline. According to(Belobaba et al. (2015, p 189): “ An airline schedule is perhaps the most important indicator of business strategy and competitive position”. This involves deciding where to fly, the frequency of the flights, and the schedules to take on these frequencies, as well as which markets to capture. 
These different strategies ultimately determine how the airline will operate and which market segments it will capture.

Some of the key considerations that airlines might face are:

•	Fleet size.
•	Types of aircrafts
•	Number of staff
•	Location of crew
•	Maintenance base
•	Slot restrictions
•	Time restrictions
•	Bilateral agreements
•	Carbon restrictions 
•	Passenger demographics

Airline schedule optimisation consists of preparing future schedules for aircraft and crew ahead of time. Its main objective is to pinpoint the profit-maximising schedules that align with the airlines’ business and strategic objectives. This is an immensely complex mission encompassing various elements.

It involves managing several airport bases with special restrictions at each airport, multiple aircraft types with different performances and maintenance schedules, and crew members from different backgrounds with their work duty limitations.

Flight planners need to consider numerous routes with different destinations and origins, each with its own unique demands and passenger demographics. They also have to manage thousands of daily flights, numerous crew pairings, and the intricacies of each route. 

Due to the numerous uncertainties and complexities of routes, decades of research have gone into models and tools that can generate route solutions. According to Belobaba et al. (2015, p. 189), these suggestions have been reported to save over $500 million for one major US carrier. 






Fleet Planning and management.

The fleet management team often does fleet planning. It typically involves optimal aircraft deployment for each route, trading, leasing, and liaising with contractors and engineering teams. 

Fleet management involves coordinating aircraft deployment and supporting services for optimal operational efficiency. Conveniently, airlines have built big teams of fleet managers and planners. However, the business models seem to be shifting towards more outsourcing to save on costs. Many airlines have changed their fleet planning teams to swap them with project managers.


As Clark (2017, p. 37) points out, flight management has gone beyond selecting the right aircraft for routes, monitoring aircraft values, trading and leasing, and managing contractors. Emirates, which uses an asset management team for its fleet management, further emphasises this. 






Effective fleet management is important to ensure that aircraft and other resources are used optimally to maximise their value while remaining strategic. The conjuncture between fleet and project management allows the airlines to minimise risks and follow the company's set guidelines; this is enabled by multiple departments working together. Clark (2017, p. 37); Cook and Billig, (2017,p 161)


Optimal gate assignment


Strategically allocating aircraft gates is crucial for optimal turnarounds, managing passenger flow, and minimizing delays; gate management systems have evolved to using real-time data and dynamically allocating gates based on live, up-to-date information such as traffic and schedules. These dynamic systems can significantly increase gate utilization and reduce delays and conflicts. Abdelghany and Abdelghany,( 2016,p 109)

At major airports with slot capacity restrictions, aircraft take off and land every few minutes. Good gate assignments are crucial for minimizing walking distances, optimizing baggage handling, and using the airline's resources more efficiently, thereby improving the passenger experience. Some of the key issues gate coordinators have to look out for are.

1.	Minimal walking distance for passengers
2.	Optimal operating costs due to cargo handling and taxi
3.	Suitable gates for the size and capacity of aircraft
4.	Avoiding adjacent gates with high wingspan aircraft
5.	Ability to adapt to delays and cancellations. Abdelghany and Abdelghany,( 2016,p 109)

Strategic allocation of gates plays an important role in minimizing delays and improving the passenger flow and experience. The use of advanced gate management systems can significantly reduce delays and increase the airport's overall throughput. Although it is a complex problem with various components, advanced approaches and innovative systems can effectively address these challenges.
