The paper attempts to give a comprehensive grasp of the issues at hand through case studies and recommendations, promoting discussion and offering tactics for the efficient administration and protection of airspace sovereignty in the constantly changing global aviation landscape.

Introduction
A key component of general international law is the idea of sovereignty over airspace, which includes states' rights and obligations to manage and control the airspace above their borders. A cornerstone of the Westphalian system, territorial sovereignty is the foundation upon which airspace sovereignty is based. It has developed over time to meet the problems posed by advances in technology, the globalisation of air travel, and changes in geopolitics.

Historically, the growth of aviation in the early 20th century gave rise to the idea of airspace as a sovereign entity. States realised that in order to protect the safety and security of their borders, regulations and standards governing the use and administration of airspace were necessary. The Chicago Convention of 1944, a crucial international accord that established the framework for the concepts of airspace sovereignty, provides clear evidence of the fruition of these efforts.

The Chicago Convention, which outlined governments' rights and responsibilities with regard to airspace sovereignty, created the fundamental framework for the management of international civil aviation. It acknowledged the notion—reiterated by later international accords and customary practices—that each state has complete and exclusive sovereignty over the airspace above its territory.

Sovereignty over airspace, as defined by general international law, gives governments the power to manage air traffic, manage entry and exit points, and implement security measures inside their airspace. States are still constrained by international treaties and accords that standardise air transport worldwide, thus this authority is not unqualified.

The Chicago Convention established the International Civil Aviation Organisation (ICAO), which is essential in promoting state-to-state collaboration to guarantee the safe and orderly functioning of air navigation. The notion of sovereignty over airspace is facing modern problems as the global aviation sector continues to change. These challenges include the development of unmanned aerial vehicles (UAVs), airspace congestion, cybersecurity threats, and environmental factors. These concerns are dynamic, thus a nuanced understanding of airspace sovereignty under general international law is required.

This has prompted continuing discussions and modifications to handle new issues as they arise. The goal of this research is to offer light on the legal foundations that support this important area of general international law by investigating the historical development, contemporary issues, and future developments surrounding the idea of sovereignty over airspace.

At a time when the world community is struggling with the growing demand for air travel and the transformative impact of emerging technologies, this study aims to provide a comprehensive understanding of the current state of airspace sovereignty. It will also offer important insights into the legal, operational, and technological considerations that will shape the future of global aviation.

The conventions, accords, and agreements reached in the area of international aviation law regarding aviation-related activities, accidents, and crimes committed on board aircraft are presented in this article. In order to perform air transport operations, it also examines how nations govern their airspace through the trade agreements they sign.

This analysis primarily states the following questions:

• What are the contemporary issues facing airspace sovereignty in relation to the use of unmanned aerial vehicles (UAVs), regional conflicts, and the influence of cutting-edge aviation technology?
• How has the concept of airspace sovereignty evolved over time, especially in light of significant international accords like the Chicago Convention of 1944?

Concept Of Sovereignty in Public International Aviation Law And It's Historical Development:
The rise of aviation, the shifting dynamics of state-to-state relations, and the requirement for cooperative frameworks to guarantee the safe and orderly use of airspace have all influenced the historical development of the notion of air sovereignty under public international law. From the earliest days of flight to the present, numerous international organisations and agreements have been established to solve the difficulties associated with the use of airspace.

Prior to the 20th century, early aviation and territorial integrity State authority over the Air was not acknowledged in the early days of aviation due to the lack of defined regulations governing airspace. Early aircraft and balloon flights were mainly uncontrolled, and there was no concern about maintaining territorial integrity.

Post-World War I: Following the war, debates over the necessity of international accords to control civil aviation began to take shape. The notion of freedom of the air during peacetime was emphasised in the 1919 Paris Convention, which set the foundation for subsequent advances.

The Chicago Convention of 1944 and the Origins of Air Sovereignty: The signing of the Chicago Convention on International Civil Aviation in 1944 marked a turning point in the development of air sovereignty as an acknowledged concept. The International Civil Aviation Organisation (ICAO) helped to establish this pact, which upheld the idea that each state has sole and absolute sovereignty over the airspace above its borders. Achieving a delicate balance between upholding states' sovereignty over their airspace and fostering international collaboration for the advancement of civil aviation was the goal of the Chicago Convention. It created the Freedoms of the Air and the International Air Services Transit Agreement, which permitted the controlled use of airspace for foreign flights.

Airspace control during the Cold War: Airspace sovereignty problems became even more important during the Cold War. As a matter of national security, states attempted to impose control over their airspace, which increased tensions about the movements of military aircraft and restricted overflights.

The idea of air sovereignty has evolved historically over a long period of time, addressing both state territory and private property rights. There have been two primary schools of thought throughout this development, up to and including the present: those who hold that property or sovereignty extends upward into the air indefinitely and those who view the airspace as free and not a property interest[1].

Article 3 of The Montevideo Convention upholds the idea that a state's political existence exists independently of its international recognition. State sovereignty includes the authority to manage internal matters, such as airspace control and regulation, and to protect their territorial integrity. The provisions of Article 3, which cover the control of airspace but do not specifically address airspace sovereignty, aid in the comprehension of state authority in the framework of public international law.

It states that, The political existence of the state is independent of recognition by other states, even before recognition, the state has the right to defend its integrity and independence, to provide for it's conservation and prosperity, and consequently to organise itself as it sees fit, to legislate upon its interests, administer its services, and to define the jurisdiction and competence of its courts. [2] The Treaty of Westphalia, which put an end to the Thirty Years' War in 1648, is sometimes cited as the source of the modern idea of state sovereignty.

The Treaty of Westphalia is seen as a turning point in the evolution of the concepts of sovereignty and the modern state structure. The Treaty of Westphalia is frequently seen as a pivotal point in the evolution of the contemporary notion of state sovereignty, but it's important to remember that the meaning and implementation of sovereignty have changed throughout time to reflect shifting social, legal, and geopolitical circumstances. The ideas outlined in Westphalia still have an impact on modern debates about statehood, diplomacy, and the use of sovereign power.

INTERNATIONAL LEGAL FRAMEWORK
States and the aviation sector have traditionally shared a specific connection. Following two catastrophic global wars, the Paris Convention and the Chicago Convention were implemented. Wars strengthen nationalism and lend a defensive quality to the noble idea of state sovereignty. The National Defence authorities of several States established a number of airlines as strategic national reserves to support the armed forces in times of war or armed conflict.

Similarly, a sizable portion of the airspace was and still is set aside for military usage. The division of airspace between military and civilian users reflects the importance placed on national security in the framework of sovereignty.

Each contracting party acknowledged that each Power has complete and exclusive authority over the airspace above their territory, according to Article 1 of the 1919 Paris Convention.

The International Civil Aviation Organisation (ICAO), a technical body of the United Nations tasked with organising and regulating transnational air transport, was founded by the Chicago Convention, also known as the Convention on International Civil Aviation. The Convention outlines the parties' rights regarding air travel, creates regulations for airspace, aircraft safety, and enrollment, and removes taxes on aviation energy. 52 nations signed the Convention on December 7, 1944, in Chicago, Illinois, and it became effective on April 4, 1947.

Along with the five official freedoms (later extended to nine by the inclusion of four unofficial freedoms) that govern a state's ability to carry out air transport operations (which encompass the movement of people, products, and mail via, into, and through the airspace of other nations). The first two of these freedoms are automatically granted to signatory nations; the public must agree to the remaining freedoms.

Airspace sovereignty freedoms include:

• 1st - Right to overfly a foreign country without landing
• 2nd - Right to refuel or carry out conservation in a foreign country
• 3rd - Right to fly from one's own country to another
• 4th - Right to fly from a foreign country to one's own
• 5th - Right to fly between two foreign countries during breakouts which begin or end in one's own
• 6th - Right to fly from one foreign country to another one while stopping in one's own country
• 7th - Right to fly between two foreign countries while not offering breakouts to one's own country
• 8th - Right to fly between two or further airfields in a foreign country while continuing service to one's own country
• 9th - Right to fly inside a foreign country without continuing service to one's own country

The Chicago Convention's Article 1 replicates this formula exactly. "For the purposes of this Convention the territory of a State shall be deemed to be the land areas and territorial waters adjacent thereto under the sovereignty, suzerainty, protection or mandate of such State" [3] is how Article 2 defines territory. Several of these terms are no longer in use or relevant. In fact, protectorates and mandates were abolished prior to the Chicago Convention coming into effect.

The Chicago Convention Was Violated in the Ryanair Aircraft Incident The forcible berthing of the RYANAIR aircraft by Belarusian authorities may have breached the Chicago Convention on International Civil Aviation. Papers 1, 3, and 3 bis emphasise the sovereignty of states over their airspace and forbid unauthorised entry or obstruction. Risk to Safety If Belarus's actions endangered the lives of those within the aircraft, the incident would have crossed the border into felonious aviation law.

In particular, Composition 3a of the Chicago Convention prohibits the use of weapons against civil aircraft and stresses that interception must not endanger human life or aircraft safety. global communication As a result of widespread international media coverage of the incident, many nations have blocked Belarusian breakouts from utilising their airspace. This response illustrates the widespread disapproval of behaviour that is thought to violate international morality and enter the civil aviation.

SANCTIONS :

• International sanctions: To implement penalties, the international community may think about working with institutions like the United Nations and the International Civil Aviation Organisation (ICAO). Articles 87 and 88 of the ICAO outline methods for resolving disputes and violations of the Convention, which may include restricting airline travel and suspending voting rights.
   
• State Countermeasures: States impacted by these infractions may choose to avenge themselves unilaterally or to bar planes from the offending state from passing over their airspace. The severity of the offence and the potential consequences will determine the type and degree of these responses.
   
• Legal implications: might include fines and penalties, including referrals to the International Court of Justice, or investigations by foreign authorities, contingent upon relevant international agreements.

CHALLENGES OF AIRSPACE SOVEREIGNTY
The basic idea of airspace sovereignty, which grants countries exclusive control over their airspace, is beset with difficulties on a worldwide scale. These difficulties, which are frequently complicated by regional dynamics, draw attention to how difficult it is to defend territorial airspace. This conversation looks at the main obstacles to airspace sovereignty and how they appear in various geographical areas.

Some Worldwide Issues With Airspace Sovereignty Are As Follows:

• Unmanned aerial vehicles (UAVs) and drones: The proliferation of drones and drone pilots has given rise to new issues in the airspace. These gadgets, which are widely available, present two risks. They may be used for illegal monitoring, which would be a breach of security and privacy. Second, since drones can be misused for evil purposes, stringent laws and preventative measures are needed.
   
• Military intrusions and geopolitical tensions: Military aircraft regularly breach sovereign airspace, either on purpose or as a result of geopolitical tensions. Such incursions heighten tensions between nations and raise the possibility of war. To prevent unintentional escalation, resolving these issues requires diplomatic dexterity and efficient communication channels.
   
• Rapid advances in technology in aviation: such as the ability to stealth and the development of hypersonic aircraft, provide difficulties for airspace control and monitoring. These sophisticated aircraft may be difficult for conventional radar systems to identify, requiring investments in cutting-edge technologies for efficient monitoring and reaction.

Minimizing challenges and ensuring airspace sovereignty:
International cooperation is necessary to address global challenges. In order to guarantee responsible behaviour in airspace, organisations like the International Civil Aviation Organisation (ICAO) are essential in fostering communication and creating uniform laws.

Technology integration: Investing in cutting-edge technologies is essential. Examples of this are anti-drone systems and AI-based aerial monitoring systems. By improving the capacity to identify and address new threats, these advancements protect aerial sovereignty.

Regional Cooperation: It's critical to acknowledge and honour regional dynamics. In order to overcome common difficulties, regional organisations like the African Union and ASEAN can promote collaboration between neighbouring states. Working together simplifies response procedures and improves sovereign airspace security as a whole.

UPCOMING ADVANCEMENTS AND REMEDIES FOR ISSUES PERTAINING TO AERIAL SOVEREIGNTY:
Emerging technologies have a significant impact on airspace sovereignty, posing both advantages and difficulties. Unmanned aircraft systems (UAS), commonly referred to as drones, are a significant technological development with a variety of applications, such as commercial deliveries and surveillance.

The proliferation of drones presents issues for traditional airspace management, since many drone applications necessitate the development of comprehensive legal frameworks to guarantee security and safety. Artificial intelligence (AI) considerably facilitates the optimisation of airspace operations. AI-based technologies will enhance air traffic control by facilitating better decision-making and optimising traffic flow.

These innovations support more effective use of resources and airspace while addressing the difficulties of controlling increasing aviation traffic. However, the incorporation of AI also prompts worries about potential flaws. Strict cyber security measures are therefore required to guard against unauthorized access and possible misuse. Radar technology has undergone significant advancements, including the usage of phased array radar and satellite surveillance systems.

These advancements strengthen situational awareness, facilitate more precise aircraft monitoring, and strengthen airspace surveillance capabilities. By identifying potential dangers and unauthorized intrusions, advanced surveillance contributes to improved aviation security.

In the research "Emerging technologies in aviation: potential benefits and risks," the European Commission highlights the need for cautious control of the deployment of these technologies despite their potential benefits. Striking a balance between resolving security and safety-related issues and reaping the benefits of technological advancements is imperative.

In the midst of changing technology landscapes, international cooperation on standards and regulatory frameworks has become crucial to guaranteeing consistent and efficient airspace sovereignty[4]. In summary, airspace sovereignty is being impacted by modern technology in a variety of ways. In order to maintain effective control of national airspace and realise the full potential of these innovations, regulatory, safety, and cybersecurity challenges must be addressed. These developments offer previously unheard-of opportunities for security and efficiency.

International cooperation: Airspace management requires international cooperation in order to guarantee the safe and efficient use of cross-border airspace. Countries will need to work together to solve concerns including traffic, safety, and environmental effect as international air travel increases. A key player in promoting this cooperation is the International Civil Aviation Organization (ICAO), a specialized agency of the United Nations[5].

The International Civil Aviation Organisation (ICAO) has established global standards and recommended practises for airspace management, which are included in the Annex of the Chicago Convention, a comprehensive international agreement governing civil aviation.

Adherence to established legal frameworks and more international cooperation are recommended as remedies for the issues that airspace sovereignty is currently experiencing. In regions of contested airspace, stepping up diplomatic efforts and fostering global conversations can aid in lowering tensions and fostering understanding. In addition, it is imperative to highlight the ways in which global organisations such as the International Civil Aviation Organisation (ICAO) facilitate collaboration and conflict resolution.

Establishing clear and widely accepted procedures for managing shared airspace is crucial, particularly in regions where disputes are likely to occur. This means advocating for the use of technology to jointly monitor and manage airspace, creating channels for cooperation and communication, and encouraging transparency in military activities.

The aviation industry will be safer and more stable if international accords are better followed and rules-based procedures are given priority. In the end, a combination of diplomatic efforts, international cooperation, and respect for established legal standards is required to tackle the complicated concerns of airspace sovereignty.

CONCLUSION
In conclusion, the topic of airspace sovereignty remains complex and dynamic within the framework of international aviation. Although sovereign rights still apply to the airspace above a country's borders, increased air travel connectivity necessitates international collaboration and legal conformity. International law, which is primarily supervised by organisations like the International Civil Aviation Organisation (ICAO), provides a foundation for the peaceful use of airspace.

However, challenges still exist, particularly in regions where there are territorial disputes and geopolitical tensions. The necessity for a careful balance between national sovereignty and the more general aspirations of the international aviation community is highlighted by events in the South China Sea, the Taiwan Strait, and the Russia-Ukraine war.

The core principle of the suggested remedies is to bolster diplomatic endeavours, promote transparency, and emphasise the role of international organisations in fostering collaboration. Clear guidelines for sharing airspace and embracing technological innovation are crucial for addressing existing problems and ensuring the sustainability and safety of international aviation.

Looking ahead, the expansion of international aviation depends on a dedication to cooperative decision-making, creativity, and adaptability. For the collective good of the global aviation community, states need to approach issues pertaining to airspace sovereignty with a forward-thinking outlook, prioritising mutual accountability and adherence to international law.
