Banking Law and Urban Air Mobility Regulation in Spain

1. Introduction

Urban Air Mobility (UAM) refers to the use of advanced aircraft, especially electric vertical take-off and landing aircraft (eVTOLs), for passenger or cargo transport within and around cities.

In Spain, UAM does not yet operate under one single “Urban Air Mobility Banking Act.” Instead, it is regulated through several overlapping areas:

• EU aviation law;
• Spanish aviation and drone law;
• EASA aircraft-certification and operational rules;
• airport and vertiport regulation;
• airspace and U-space regulation;
• environmental and urban-planning law;
• payment and financial-services regulation;
• banking, lending and leasing rules;
• competition and State-aid law.

The banking-law dimension becomes important because UAM projects require substantial capital for aircraft, vertiports, charging infrastructure, software, insurance and fleet operations.

Therefore, Spanish banks financing UAM projects must assess not only the borrower's creditworthiness but also whether the underlying aviation project is legally capable of operating.

2. What Is Urban Air Mobility in the Spanish Context?

UAM generally includes:

1. passenger eVTOL services;
2. air taxis;
3. urban cargo drones;
4. medical and emergency UAS operations;
5. vertiports;
6. charging infrastructure;
7. fleet-management systems;
8. autonomous or highly automated aircraft;
9. digital air-traffic-management systems;
10. connections between airports, cities and transport hubs.

A useful legal distinction is:

UAS-based UAM

This includes unmanned aircraft and drone operations.

Manned eVTOL UAM

This includes aircraft carrying passengers and therefore falls much more heavily within conventional aviation certification and operational regulation.

This distinction is important for banks because the regulatory risk of the financed asset depends upon which category the project belongs to.

3. Main EU Legal Framework

Spain is an EU Member State, so much of the important aviation framework comes directly from EU law.

A. Regulation (EU) 2018/1139

This is the basic EU aviation framework establishing common rules in civil aviation and creating the institutional framework for EASA.

For UAM financing, it matters because aircraft and aviation products need to satisfy applicable EU safety requirements.

A bank financing an eVTOL cannot simply treat it like an ordinary vehicle.

The aircraft may need:

• type certification;
• airworthiness approval;
• operational approval;
• qualified operators;
• maintenance arrangements;
• safety-management systems;
• appropriate insurance.

If these conditions are not satisfied, the economic value of the financed aircraft may be substantially reduced.

4. EU Drone and U-Space Regulation

For drone-based UAM, two major areas are particularly important.

Regulation (EU) 2019/947

This establishes rules and procedures for the operation of unmanned aircraft.

Regulation (EU) 2019/945

This establishes requirements concerning unmanned aircraft systems and their operators.

Regulation (EU) 2021/664

This creates the EU regulatory framework for U-space.

U-space is particularly important for future urban air mobility because cities may have many aircraft operating simultaneously.

It addresses matters such as:

• flight authorisation;
• network identification;
• traffic information;
• airspace management;
• information services;
• coordination between UAS operators.

For a bank, this produces an important financing question:

Can the proposed UAM business legally obtain and maintain the airspace access necessary to generate revenue?

5. Spanish Regulatory Framework

Spain implements and supplements the EU framework through its national aviation institutions and legislation.

The principal authorities include:

AESA

The Agencia Estatal de Seguridad Aérea (AESA) is Spain's principal civil aviation safety authority.

It has important responsibilities relating to:

• UAS;
• aviation safety;
• operators;
• aircraft;
• operational requirements;
• authorisations and supervision.

Ministry of Transport and Sustainable Mobility

The Ministry has broader responsibility for transport and aviation policy.

ENAIRE

ENAIRE has major responsibilities concerning Spanish air navigation and air-traffic-management infrastructure.

For UAM, coordination between aircraft operators, vertiports, U-space services and conventional airspace becomes particularly important.

6. Spanish UAS Framework

Spain adopted Royal Decree 517/2024, which provides additional national rules concerning UAS operations and establishes measures for implementing the EU drone framework.

This is important for UAM because Spain must integrate drone operations into:

• national airspace;
• protected areas;
• urban environments;
• security-sensitive areas;
• airports;
• infrastructure;
• emergency services.

Consequently, financing a drone-UAM company involves regulatory due diligence concerning the company's ability to conduct its proposed operations.

7. Why Banking Law Matters

UAM is primarily an aviation-regulatory subject, but banking law becomes important whenever a financial institution provides funding.

A Spanish bank might finance:

Aircraft

For example:

• eVTOL aircraft;
• drone fleets;
• replacement batteries;
• avionics.

Vertiports

Funding may cover:

• construction;
• landing infrastructure;
• passenger facilities;
• charging systems;
• safety equipment.

Digital infrastructure

Loans could finance:

• U-space systems;
• flight-management platforms;
• identification systems;
• cybersecurity infrastructure.

Fleet leasing

A bank or leasing company may finance aircraft and lease them to the UAM operator.

Project finance

A large vertiport or UAM network could potentially be structured as a project-finance transaction.

8. Regulatory Due Diligence Before UAM Financing

A Spanish bank should normally examine several layers of risk.

8.1 Aircraft certification

The lender should determine whether the aircraft has the necessary regulatory status.

An uncertified aircraft can represent a very weak collateral asset.

8.2 Operator authorisation

The bank should verify whether the borrower is legally capable of operating the aircraft.

A company may have an excellent business plan but still be unable to operate commercially without the required aviation approvals.

8.3 Vertiport permissions

The lender should examine:

• land rights;
• planning permission;
• aviation permissions;
• safety requirements;
• environmental requirements;
• access to electricity;
• charging infrastructure;
• connection to transport networks.

A bank financing a vertiport therefore needs much more than a normal property-security assessment.

9. Collateral Issues

UAM creates unusual collateral questions.

Suppose a bank lends €100 million to a company purchasing eVTOL aircraft.

The bank may take security over:

• aircraft;
• shares;
• receivables;
• insurance proceeds;
• leases;
• equipment;
• charging infrastructure.

But the bank must ask:

What happens to the collateral if the aircraft loses its aviation certification?

The economic value of the aircraft may fall significantly.

Therefore, aviation regulatory compliance becomes a credit-risk issue.

10. Aircraft Leasing and Banking

Leasing could become particularly important in Spanish UAM.

Instead of purchasing aircraft outright, an operator could obtain them through:

• operating leases;
• finance leases;
• secured lending;
• sale-and-leaseback structures.

The financial institution would need to understand:

• ownership;
• registration;
• possession;
• maintenance obligations;
• insurance;
• repossession;
• regulatory restrictions;
• cross-border movement of aircraft.

The legal ability to repossess and remarket the aircraft is particularly important.

11. Payment and Consumer-Finance Issues

A UAM operator could sell tickets through:

• mobile applications;
• digital wallets;
• bank cards;
• subscription models;
• mobility platforms.

Where financial services are separately provided, EU payment-services rules can become relevant.

The bank financing the platform should also consider:

• customer funds;
• payment processing;
• fraud;
• cybersecurity;
• refunds;
• data protection;
• outsourcing.

If a UAM platform combines transportation with financial services, the regulatory perimeter becomes more complicated.

12. ESG and Green Finance

Electric UAM is often promoted as a sustainable transportation technology.

Banks may therefore consider:

• green loans;
• sustainability-linked loans;
• green bonds;
• infrastructure financing;
• EU-supported financing.

But a bank should not assume that every eVTOL project automatically qualifies as “green.”

It should examine:

• lifecycle emissions;
• electricity source;
• battery production;
• charging infrastructure;
• noise;
• land use;
• actual substitution of higher-emission transport.

Green-finance claims must be supported by appropriate evidence.

13. State Aid and Public Financing

UAM infrastructure may require public-sector participation.

For example:

• government grants;
• municipal infrastructure;
• public guarantees;
• subsidised loans;
• airport support;
• research funding.

EU State-aid law can therefore become relevant.

A Spanish bank participating in a publicly supported UAM project must determine whether the financing structure complies with EU State-aid rules.

14. Competition Law

UAM infrastructure could become a bottleneck.

Consider a situation where one company controls the only commercially viable vertiport in a major Spanish city.

Competitors may need access to it.

Competition-law questions could then concern:

• refusal of access;
• discriminatory access;
• excessive prices;
• exclusive agreements;
• dominant position;
• interoperability.

This matters to banks because a monopoly-dependent UAM business model may have significant regulatory risk.

15. Data and Cybersecurity

Modern UAM will depend heavily on digital infrastructure.

Banks financing UAM should therefore assess:

• aircraft telemetry;
• passenger information;
• location data;
• identity systems;
• U-space data;
• cybersecurity;
• cloud infrastructure;
• AI systems.

Cybersecurity failure can cause both operational and financial losses.

For larger financial institutions, EU operational-resilience requirements can also become relevant to the bank itself when it provides or relies upon digital services.

16. Insurance and Banking Risk

Insurance is another important component.

A lender may require insurance covering:

• aircraft;
• liability;
• passenger risks;
• infrastructure;
• cyber risks;
• business interruption.

The financing documents may require the lender to receive appropriate rights over insurance proceeds.

Without adequate insurance, the bank's exposure may become significantly greater.

17. Environmental and Urban-Planning Regulation

UAM cannot operate simply because an aircraft is aviation-certified.

A vertiport must also fit into the relevant physical and regulatory environment.

Issues can include:

• noise;
• land use;
• building regulations;
• environmental assessment;
• public safety;
• local planning;
• electricity infrastructure;
• emergency access.

Therefore, aviation approval and urban-planning approval are separate questions.

This is a major issue for project finance.

18. Key Case Laws

There are currently relatively few reported Spanish or EU judicial decisions dealing specifically with commercial eVTOL UAM financing. It would therefore be incorrect to invent UAM-specific banking cases.

The following EU decisions are important because they establish legal principles that can apply to the financing, infrastructure, competition and public-support dimensions of UAM.

Case 1 — Aéroports de Paris v Commission

Case C-82/01 P, Aéroports de Paris v Commission

The CJEU examined the economic activities of airport infrastructure and the application of competition law.

Importance for UAM

The case is useful when considering whether the operation of aviation infrastructure such as a vertiport can constitute an economic activity.

This matters for:

• competition law;
• infrastructure access;
• public financing;
• discriminatory treatment;
• market power.

Case 2 — Leipzig/Halle Airport

Joined Cases T-443/08 and T-455/08, Freistaat Sachsen and Land Sachsen-Anhalt v Commission

The EU courts considered the financing of airport infrastructure and its relationship with EU State-aid law.

Importance for UAM

This is highly relevant by analogy to publicly supported:

• vertiports;
• charging infrastructure;
• aviation infrastructure;
• airport-UAM connections.

It demonstrates why public funding of transport infrastructure can raise State-aid questions.

Case 3 — Altmark

Case C-280/00, Altmark Trans GmbH

The CJEU established important principles concerning compensation for public-service obligations.

Importance for UAM

A Spanish authority might potentially support a UAM service designed to provide public transport connectivity.

If public money compensates an operator for public-service obligations, the Altmark principles may become relevant.

For banks, this affects the predictability of public revenue supporting the project.

Case 4 — Stardust Marine

Case C-482/99, France v Commission

The CJEU considered when State resources and State influence may be relevant under EU State-aid law.

Importance for UAM

It is relevant where Spanish public bodies or publicly controlled entities participate in financing:

• UAM operators;
• vertiports;
• infrastructure companies;
• aviation technology companies.

A lender should understand whether government-backed financing creates State-aid exposure.

Case 5 — Ryanair v Commission

Joined Cases T-238/20 and T-259/20

The General Court examined State-support measures directed toward airlines during the COVID-19 crisis.

Importance for UAM

The decisions illustrate the extensive role of EU State-aid law in aviation financing.

They are relevant to future public support for UAM operators because governments may seek to support strategically important transport companies.

Case 6 — Ryanair v Commission

Case T-225/20, Ryanair v Commission

The General Court addressed another State-aid measure involving the aviation sector.

Importance for UAM

The case illustrates that selective government financial assistance to aviation businesses must be assessed against EU State-aid requirements.

This is particularly important where UAM companies compete with conventional airlines, taxis or other mobility providers.

Case 7 — Deutsche Lufthansa v Commission

Case T-34/21, Ryanair v Commission and related aviation State-aid litigation

The EU courts dealt with the legality of State support to aviation companies during the pandemic.

Importance for UAM

The broader lesson is that government-backed aviation finance can have competition-law consequences.

A Spanish bank participating in a publicly supported UAM financing structure should therefore examine the legal basis of that support.

Case 8 — Kotnik

Case C-526/14, Kotnik and Others v Državni zbor Republike Slovenije

The CJEU examined EU banking-sector State-aid principles, particularly the treatment of bank restructuring and burden sharing.

Importance for UAM banking

Although this was not an aviation case, it is important for the banking side of the analysis.

It demonstrates that public intervention involving banks can be subject to EU State-aid disciplines.

This becomes relevant if a Spanish bank receives public support while financing strategic UAM infrastructure.

Case 9 — Ledra Advertising

Joined Cases C-8/15 P to C-10/15 P, Ledra Advertising Ltd and Others

The CJEU examined legal issues arising from financial assistance and the responsibilities of EU institutions.

Importance for UAM finance

The broader lesson is that financial-stability and public-finance measures remain subject to legal constraints.

This is relevant when UAM financing involves:

• EU institutions;
• public guarantees;
• financial assistance;
• large infrastructure programmes.

Case 10 — Bronner

Case C-7/97, Oscar Bronner GmbH

The CJEU established important principles concerning access to essential facilities and refusal to deal.

Importance for UAM

The case becomes relevant by analogy where an essential UAM infrastructure facility is controlled by a dominant company.

For example:

If one operator controls an essential vertiport and refuses competitors reasonable access, competition law may become relevant.

This can directly affect the bankability of competing UAM businesses.

19. Practical Banking-Risk Matrix

20. Example of a Spanish UAM Project-Finance Structure

Imagine a company proposes a €250 million UAM network in Madrid.

The project includes:

• 30 eVTOL aircraft;
• 5 vertiports;
• charging stations;
• digital booking systems;
• U-space integration;
• maintenance facilities.

A Spanish bank considers providing €150 million of debt.

Before approving the loan, the bank should examine:

Step 1 — Corporate borrower

Is the company properly incorporated and financially capable?

Step 2 — Aircraft

Are the aircraft appropriately certified and legally operable?

Step 3 — Operator

Does the company possess the required aviation approvals?

Step 4 — Vertiports

Are land, planning and aviation permissions available?

Step 5 — Airspace

Can the proposed routes actually operate?

Step 6 — Revenue

Are passenger forecasts realistic?

Step 7 — Security

Can aircraft, shares, receivables and insurance proceeds be secured?

Step 8 — Public support

Does any government guarantee or subsidy comply with EU law?

Step 9 — Competition

Could access to critical infrastructure create competition problems?

Step 10 — Exit

If the borrower defaults, can the bank sell or lease the aircraft and other assets?

This shows why UAM regulation becomes a direct component of banking credit analysis.

21. Key Legal Principle

The most important principle is:

A bank financing UAM in Spain is not merely financing an aircraft; it is financing a regulated aviation ecosystem.

The value of the investment depends on the interaction between:

aviation certification + airspace access + operator authorisation + vertiport permissions + urban planning + infrastructure + environmental compliance + competition law + financial regulation.

A failure in one layer can affect the entire financing structure.

22. Conclusion

Spain's UAM framework is primarily built from EU aviation law, EASA rules, Spanish aviation legislation, UAS/U-space regulation and national administrative law, rather than from a standalone UAM Banking Act.

For banking purposes, the most important issues are:

1. certification of eVTOL/UAS assets;
2. legal authorisation of operators;
3. vertiport and infrastructure approvals;
4. U-space and airspace access;
5. aircraft leasing and security;
6. project-finance structures;
7. insurance and collateral protection;
8. State-aid rules for public financing;
9. competition law concerning essential infrastructure;
10. cybersecurity and digital infrastructure;
11. environmental and urban-planning requirements;
12. long-term regulatory risk affecting the bankability of the project.

The important case-law point is that there is not yet a mature body of Spanish case law specifically on “UAM banking law.” The strongest legal analysis therefore uses directly relevant EU aviation, infrastructure, competition, State-aid and banking decisions—such as Aéroports de Paris, Leipzig/Halle, Altmark, Stardust Marine, Ryanair, Deutsche Lufthansa, Kotnik, Ledra Advertising and Bronner—rather than presenting unrelated cases as UAM-specific precedents.
