Zurich AirportSkyguide secretly lifts capacity restrictions
Despite the announced extension of capacity reductions, Skyguide has surprisingly lifted the restrictions already. The decision was not communicated publicly.

At the beginning of July, a software glitch at Skyguide caused significant disruptions at Zurich Airport with 68 affected flights, including 18 cancellations and 31 delays.
Despite the previously announced capacity reduction until further notice, this was already lifted on July 12 without public announcement.
A global IT outage at Crowdstrike temporarily caused chaos at Zurich Airport, but there were no long-term capacity restrictions from Skyguide.
At the beginning of July, a software glitch at the Swiss air navigation service Skyguide caused significant disruptions at Zurich Airport. Approximately 68 flights were affected, including 18 canceled departures and 19 arrivals, as well as 31 delayed flights with delays of up to two hours. A total of 17 Swiss flights had to be canceled, affecting 1900 passengers.
Skyguide responded to the glitch by convening a task force. Already in April, Skyguide CEO Alex Bristol had announced a temporary capacity reduction until June 2024 to create a safety buffer and more leeway for air traffic controllers.
Capacity restriction has been lifted
Although two software updates were made, Skyguide spokesperson Barrosa stated that the capacity reduction would remain in effect for the time being. However, in a statement to 20 Minuten, Skyguide has now indicated that the capacity restriction of 20 percent for arrivals, departures, and transit traffic was already lifted on July 12. This decision was not publicly communicated, as it was considered an internal operational matter, according to the Skyguide spokesperson. “Our partners were informed about the lifting.”
The capacity reduction was criticized as the safety margin of 20 percent was deemed too high. Barrosa defended the measure as a necessary step for safety in the airspace and emphasized that the reduction was only applied to the maximum available capacity. “If capacity was already reduced, for example due to bad weather, no additional reduction was made.”
No capacity restrictions during the Crowdstrike incident
Last Friday, in the midst of the summer holidays, a massive IT failure worldwide caused chaos – Zurich Airport was also affected, and for a period, no landings were possible. The cause was a faulty software update from the cybersecurity platform Crowdstrike.
During the Crowdstrike incident, there were already no capacity restrictions in effect from Skyguide. “A short-term reduction was implemented in the morning to check whether Skyguide’s air traffic control systems were affected, which was not the case,” Barrosa explained. The approaches to Zurich were stopped or reduced at the request of the airport due to the parking situation. After a short interruption, Skyguide was able to operate again at full capacity.

Future Trends in Air Traffic Management and Cybersecurity
The recent developments at Zurich Airport, particularly the unexpected lifting of capacity restrictions by Skyguide, highlight the evolving landscape of air traffic management. Initially implemented as a safety measure following a significant software failure, the decision to remove these restrictions suggests a possible shift towards greater operational flexibility within the aviation industry.
Increased Adaptability in Air Traffic Control
Expectations for air traffic management are increasingly leaning towards adaptability. As seen with Skyguide’s rapid response to operational constraints, airports and air traffic controllers may adopt more agile protocols to handle unforeseen circumstances. This could involve real-time adjustments to capacity based on immediate conditions, whether they be technical glitches or environmental factors.
Integration of Advanced Technologies
The reliance on technology such as software updates and cybersecurity measures reveals a growing trend toward integrating advanced technologies into air traffic management. The recent chaos caused by a worldwide IT issue from Crowdstrike underscores the importance of robust cybersecurity systems. Moving forward, airports may invest in more resilient IT infrastructures to safeguard against such vulnerabilities, ensuring smoother operations in the face of potential digital threats.
Enhanced Communication Strategies
The lack of public communication regarding the lifting of capacity restrictions raises questions about transparency in the aviation industry. Future trends may see airports and air traffic management organizations enhancing their communication strategies. Clear and timely updates on operational changes could improve traveler confidence and mitigate frustration during disruptions.
Focus on Passenger Experience
With airlines and regulators increasingly prioritizing customer experience, the ability to quickly adjust to capacity needs will likely become a competitive advantage. Airports that can maintain high service levels, even during technical difficulties or staffing shortages, will have a significant edge in attracting travelers. Enhanced passenger flow management techniques and customer communication tools are expected to become integral parts of air traffic management strategies.
