AVISTRAT-CH: Redesigning Swiss airspace
Overview
- Switzerland’s airspace has become very complex. Airspace violations and unauthorised approaches by aircraft are on the increase. There are also new things to deal with, such as drones.
- The FOCA's response to this is AVISTRAT-CH, a programme which covers both airspace and infrastructure on the ground.
- The aim: to provide a safe, efficient and environmentally sustainable system that meets future usage requirements.
- The strategy: to create a flexible airspace and an optimised Swiss airport system through coordinated activities in 25 areas of action.
- Implementation: in stages. Two sub-projects are currently under way to set the foundations on which further activities are to be based. The Air Force, air management, aerodromes and the aviation industry are involved.
Why does Switzerland need AVISTRAT?
Switzerland's airspace and aviation infrastructure (air traffic management infrastructure and aerodromes) is a system that has grown over decades and has been repeatedly and incrementally modified throughout that period. Flying in this fragmented airspace has become increasingly complicated and challenging. New demands on airspace have emerged recently, such as drone operation.
The increasing number of airspace violations, some of which have also affected scheduled and charter flights, indicates that the existing system no longer meets current requirements. Action needs to be taken. The Swiss Transportation Safety Investigation Board (STSB) has also made various recommendations to this effect.
The mandate
In mid-2016, DETEC instructed the Federal Office of Civil Aviation (FOCA) to optimise the organisation of Swiss airspace, taking into account the impact of aviation infrastructure. To this end, the FOCA set up a programme called the Airspace and Aviation Infrastructure Strategy of Switzerland, or AVISTRAT-CH for short. AVISTRAT-CH aims to reduce the risks associated with using Swiss airspace and to ensure that this limited resource is deployed efficiently, with as much regard for the environment as possible.
The AVISTRAT vision
To provide a safe, efficient and environmentally sustainable system that meets future usage requirements.
The strategy
In a series of coordinated activities in 25 areas of action, to establish an optimised, coordinated Swiss aerodrome system in Switzerland and create an airspace which meets the needs of all users.
Implementation
A number of activities are already taking place in the 25 areas of action outside the AVISTRAT-CH programme; the results of these will also feed into achieving the AVISTRAT-CH objectives.
Two sub-projects have been launched specifically for AVISTRAT-CH, relating to the two strategic priorities mentioned in the strategy report. These address the coordinated development and use of the aerodrome system and airspace access using equipment. The aim of these sub-projects is to establish the necessary foundations for directional decision-making by 2025. The lead responsibility for the Swiss aerodrome system lies with the infrastructure operators, with the FOCA providing support. The FOCA is responsible for optimising Swiss airspace.
Sub-project: Coordinated development and use of the aerodrome system
The Swiss Aerodromes Association (SAA) is currently analysing the development trends of the more than 50 Swiss regional aerodromes. The first results are expected by the end of 2024.
Indicative roadmap:
Moving forward, the aim is for the Swiss aerodrome system to be able to integrate new types of air traffic and allow competence clusters at aerodromes, to increase safety thanks to a more coordinated and comprehensive system, and to make the aviation system more economically, socially and ecologically sustainable in general. In addition, the issue of the displacement of general and business aviation from the international airports will be addressed.
Strategic Initiative “Access to the airspace using equipment” (SI-2-4)
This strategic initiative defines which services should be used in the future for an optimal use of the airspace and which technologies will enable this. With the FASST-CH (Future Aviation Surveillance Services and Technologies in Switzerland) project, the FOCA is laying the foundation for defining the services and technologies (including infrastructures) to enable a simplified access to the respective airspace. This will be realised by establishing a holistic i-Conspicuity ecosystem.

Cronoprogramma indicativo:
The implementation of the strategic initiative ‘Access to the airspace using equipment’ (SI-2-4) will create the conditions for realising the strategic initiatives ‘Targeted development of the airspace’ (SI-2-1) and ‘Dynamic management of the airspace’ (SI-2-3).
The envisaged optimised airspace should create demand-oriented airspaces that can be quickly and flexibly adapted, enable increased capacity and more efficient flight routes, create increased safety through electronic visibility and simpler airspace structures, as well as simplify the integration of new types of traffic. Particular attention is paid to the safety of air traffic in the vicinity of the national airports of Basel, Geneva and Zurich.
Stakeholder involvement
In some cases it is necessary and desirable to involve aviation stakeholders when establishing the principles of the AVISTRAT-CH programme. As soon as the bases for discussion are established, the usual processes are launched and stakeholders and interest groups consulted.
