What is SIGN-AIR

SIGN-AIR is a SESAR Fast-Track project focused on enhancing multimodal travel by automating the management of data-sharing agreements between Transport Service Providers (TSPs). Through Data Sharing Agreements (DSAs) and Smart Contracts (SCs), SIGN-AIR enables seamless data exchange while ensuring compliance with regulatory frameworks.

Simulation Environment

The experiment takes place in a dedicated test room at ENAC, utilising the GENETICS Airbus Defence and Space platform, which includes:

ENAC’s role in PRIAM

ENAC contributes to the project by extending its optimisation methods for multimodal transport networks to new emerging mobility modes like IAM. Our work focuses on the development of an optimisation model that synchronizes IAM services with other transport modes, leveraging multimodal data sharing to enhance passenger experience while considering IAM-specific constraints like battery charging.

ENAC’s role in ATMACA

ENAC is researching ATMACA applications for Green Route Operations. The new ATMACA communication protocol, with its Air-to-Ground instant text messaging capability, would enable aircraft to share real-time weather information (wind and temperature) with ground units.

Accurate real-time weather data will enhance:

What’s new and what improvements?

• Replacement of the former lamp projectors with latest-generation laser technology
• Reduction of the number of projectors by a third: two projectors needed for 120° instead of three and therefore reduction of the maintenance burden and its cost
• Increase in resolution from 2K to 4K, guaranteeing an even more realistic simulation that allows better visibility of distant traffic and obstacles

A technological challenge successfully met

One of the major challenges of this upgrade was to adapt the image

At the Digital Sky Marketplace, SESAR projects presented innovative and sustainable Air Traffic Management (ATM) solutions across key domains:

U-SPACE & Urban Air Mobility

• EUREKA (SESAR 3 Fast Track project) – A European solution for vertiports and Urban Air Mobility (UAM).

Multimodality & Passenger Experience

• SIGN-AIR – Transforming data-sharing across Europe to enhance multimodal transportation.

AI for Aviation

This partnership aims to establish joint training programmes tailored to the needs of the industry, organise large-scale scientific and industrial events, and facilitate student and faculty exchanges between the partner institutions. It is fully aligned with Qatar’s National Vision 2030, which aims to develop a high-performing and innovative aviation sector on an international scale.

Five scenarios were explored, each highlighting different conditions for using airspace. These scenarios included a number of key players:

• Maturing key deliverables:  OSED (Operational Service and Environment Description), Technical Specifications, Cost-Benefit Analysis Standards and Regulations
• Refining Validation Plans, including human performance and safety assessments, to prepare for the upcoming wave of exercises planned in 2025 to validate the concept.
