ICAO Discovers That Aviation Has Changed - Now It Needs to Tell the Lawyers

By Garth Calitz

Uncrewed aircraft, cyber threats, satellite navigation, airport charges and data protection are suddenly demanding attention from international aviation regulators. At its 40th Legal Committee session, ICAO has identified a long list of challenges facing modern aviation. The question is whether another round of committees, recommendations and non-binding guidance will actually make a difference.

There is something rather reassuring about the International Civil Aviation Organisation (ICAO). Just when the aviation industry thinks it has encountered every possible regulatory complication, ICAO convenes another committee, produces another set of recommendations and reminds everyone that international aviation needs a modern legal framework.

This time, the organisation has turned its attention to something rather obvious to the rest of the industry for some time: aviation has changed considerably since 1944. The 40th session of the ICAO Legal Committee has concluded with a collection of recommendations addressing uncrewed aircraft, cyber threats, satellite navigation, airport charges, data protection and the interpretation of existing international aviation law.

All worthwhile subjects. All deserving of attention. And, in fairness, all rather important if the industry intends to make it to 2050 without drowning in its own regulatory paperwork. The problem is that identifying the issues and actually resolving them are two entirely different exercises.

The Chicago Convention remains the foundation of international civil aviation. Signed in 1944, it established the principles governing international air transport and created ICAO as the organisation responsible for overseeing the development of global aviation standards. It was an extraordinary achievement for its time.

However, the aviation world of 1944 consisted of piston engines, propellers, paper charts and pilots who generally had the considerable advantage of being physically present in the aircraft. Today, we have remotely piloted aircraft, increasingly autonomous systems, electric vertical take-off and landing aircraft, artificial intelligence, satellite-based navigation and digital systems connecting almost every aspect of aviation operations. Somewhere along the way, the legal framework has struggled to keep pace.

ICAO's Legal Committee has now acknowledged that existing international instruments need further examination to determine how they apply to aircraft operating without pilots on board. This is sensible, although one might reasonably ask why the legal profession appears to be arriving at the party several years after the technology developers.

The challenge is not simply deciding whether an uncrewed aircraft is an aircraft. It is determining who carries legal responsibility when something goes wrong, how international operations should be authorised, which State has jurisdiction and how liability should be apportioned when an autonomous aircraft crosses several national borders.

These are not minor technicalities. They are fundamental questions that need answers before autonomous aviation becomes a mainstream commercial reality. For now, ICAO wants further work to avoid fragmented national regulations. In other words, the industry has developed the technology, and the lawyers are still working out who gets to sign the paperwork.

Another subject receiving attention was Article 15 of the Chicago Convention, dealing with airport and air navigation facility charges. This is particularly interesting because airport charges have become an increasingly sensitive issue for airlines, airports and air navigation service providers.

ICAO wants greater clarity, consistency and predictability in how these charges are interpreted and applied. The Committee acknowledged that States hold differing views about the extent of their obligations under Article 15 and how compliance should be ensured. One would have thought that after more than eight decades, the international aviation community might have settled on a reasonably consistent interpretation of airport charging principles. Apparently not.

For airlines, airport and navigation charges are significant operating costs. For airports and air navigation providers, they are necessary to fund infrastructure, technology and operations. The real issue is ensuring that charges are transparent, justified and applied fairly.

This is particularly relevant in South Africa, where the cost of operating through major airports and navigating the regulatory environment is a recurring concern for the aviation industry.

Perhaps ICAO could eventually produce something more useful than another set of recommendations: a practical mechanism for ensuring that charging principles are consistently applied. The industry would probably appreciate that more than another invitation to participate in a consultation process.

The Legal Committee also examined whether existing international aviation conventions adequately address cyber threats and emerging forms of criminal activity. This is arguably one of the most important issues on the agenda.

Modern aviation depends on interconnected digital infrastructure. Air traffic management, airline operations, airport security, aircraft communications, navigation and passenger information systems all rely on technology that potentially creates new vulnerabilities.

A successful cyberattack against an aviation organisation could cause disruption extending well beyond a company's IT department. It could affect aircraft movements, airport operations and the safety of passengers. ICAO has identified potential gaps in existing international legal instruments and believes further work is necessary.

That is encouraging, but cybersecurity is not waiting for international lawyers to finish their deliberations. Threats evolve rapidly, and the consequences of failing to protect aviation infrastructure could be considerable. The industry needs clear responsibilities, effective international cooperation and enforceable security requirements. It also needs regulators to recognise that cybersecurity is now an integral component of aviation safety.

Aviation cannot afford to treat cyber threats as something to be discussed at the next committee meeting.

ICAO also considered the legal implications of global satellite navigation systems. Modern aviation is increasingly dependent on satellite-based navigation, making the reliability, security and legal status of these systems essential to international operations.

The Committee agreed to retain the subject in its work programme while coordinating with other United Nations organisations to avoid duplication. That last point is particularly interesting. International organisations avoiding duplication is rather like airlines avoiding delays: everyone supports the principle, but the practical implementation can be challenging.

International airlines operate across multiple jurisdictions, each with potentially different requirements governing the collection, storage and transfer of personal information. ICAO believes additional guidance could help reduce conflicts between national and regional legislation. It is a legitimate concern, although airlines might be forgiven for wondering how many more compliance departments they will need before the next passenger boards an aircraft.

One of the more practical outcomes involved Article 12 of the Chicago Convention, which requires States to enforce the Rules of the Air. The Committee endorsed guidance documents and supported the development of a web-based tool to help States implement their obligations. This is intended to reduce uncertainty for international operators. The important qualification is that the proposed tools are facilitative and non-binding.

There is nothing inherently wrong with guidance. In fact, practical assistance for States with limited regulatory resources is welcome. However, aviation safety depends on consistent application of rules, not simply the availability of guidance explaining what those rules should be. A web-based tool is useful. Actual implementation is considerably more important.

All these initiatives support ICAO's broader strategic vision for 2050: air transport for all, zero fatalities and net-zero carbon emissions. It is an impressive ambition. However, zero fatalities is an extraordinarily demanding objective in an industry involving millions of flights, thousands of operators and hundreds of national regulatory authorities.

Net-zero aviation is equally challenging, requiring technological advances, sustainable aviation fuels, new propulsion systems and significant infrastructure investment. None of these objectives will be achieved through legal frameworks alone. They require practical investment, competent regulators, properly trained personnel, effective safety oversight and a willingness by governments to implement what they have agreed to internationally. There is also the small matter of ensuring that aviation remains commercially viable while all these ambitions are pursued.

For South African aviation, ICAO's deliberations should not be dismissed as another international regulatory exercise taking place somewhere between Montreal and Geneva. The implications are very real.

The South African Civil Aviation Authority will eventually have to address many of the same questions involving autonomous aircraft, remotely piloted operations, cybersecurity, satellite navigation and international data protection requirements. South Africa's general aviation sector also has a particular interest in how international regulatory developments are translated into domestic legislation.

The industry has already experienced its fair share of regulatory frustration, with concerns about compliance costs, administrative processes, certification requirements and the practical consequences of regulatory decisions. There is a danger that the introduction of new technologies will simply provide another opportunity to expand regulatory complexity without necessarily improving safety or operational efficiency.

South Africa needs modern, internationally aligned regulations, but it also needs regulation that is proportionate, understandable and practical. The objective should be to enable safe aviation, not make participation in aviation increasingly expensive and administratively exhausting.

ICAO deserves credit for recognising that international aviation law must evolve. Its Legal Committee has identified several important areas where existing conventions and legal interpretations need attention. But there is a familiar pattern emerging.

A problem is identified. A committee studies it. Recommendations are developed. The recommendations are submitted to the Council. Further work is proposed. States are encouraged to participate, and somewhere down the line another committee will probably review progress. Meanwhile, the aircraft keep flying, the technology keeps advancing and the industry continues to deal with the consequences.

The real measure of success will not be the number of recommendations adopted, guidance documents published or workshops conducted. It will be whether international operators experience clearer rules, whether States implement them consistently, whether cyber vulnerabilities are reduced, whether airport charges become more transparent and whether emerging aircraft technologies can operate safely across borders.

ICAO has correctly identified that aviation is changing. Nobody in the industry needed a committee to confirm that. What the industry needs now is action. Because by 2050, there is every possibility that aircraft will be flying autonomously, airports will be managing entirely new classes of vehicles and artificial intelligence will be making decisions that today's regulators have barely begun to contemplate. One hopes that by then, ICAO will have moved beyond discussing the problem.

After all, the aircraft may be autonomous, but the regulatory process appears determined to remain firmly on manual control.
