Summary
Zurich Airport plans to allow aircraft to depart southward on approximately 18 days per year (during föhn winds). The concept "Departure 16 degrees" is intended to increase safety margins and reduce delays. Affected municipalities and cities reject this—they fear noise pollution and crash risks for densely populated areas. Resistance is substantial; the Federal Office is now reviewing all objections.

Zurich Airport applied to the Federal Office of Civil Aviation for approval of south departures on runway 16—a new operational concept designed to alleviate operational conflicts during föhn winds. The Federal Office is to review all objections; implementation at the earliest in 2027. Opposition is massive: affected municipalities and cities—including Zurich, Uster, and Tübendorf—warn against uncontrolled aircraft noise over densely populated areas and crash risks from fully loaded large aircraft.
Detailed Summary
Operational Problem & Planned Solution
During föhn winds (föhn conditions), Zurich Airport faces an operational bottleneck: aircraft cannot simultaneously depart and land because flight paths would intersect. The new regulation aims to address this through south departures on runway 16. According to airport spokesperson Bettina Kuhn, this concept would be used only during approximately 5% of operating times—about 18 days per year. This would increase safety margins and reduce delays.
Massive Resistance from Affected Regions
The south of the airport is densely populated. Urban Scherer, president of the Association Flight Corridors South-Nei, warns: such a flight procedure would affect thousands of residents across the entire city of Zurich—a risk that should not exist. In addition to noise pollution, opponents fear safety risks: fully loaded large aircraft over densely populated areas. Several municipalities and the cities of Zurich, Uster, and Tübendorf filed objections.
Confidence in Regulation Questionable
South departure opponents fear that an exception for föhn days will soon become standard practice. The airport spokesperson emphasizes instead: the Federal Council has bindingly fixed the use to föhn days; Sky Guide (air traffic control) cannot simply switch. Nevertheless, mistrust remains—a classic regulatory problem between efficiency goals and noise protection.
Key Points
- The airport plans south departures during föhn winds to alleviate operational conflicts
- Affected areas are densely populated; noise pollution and crash risks are real
- The Federal Office is reviewing objections; implementation at the earliest in 2027
- Opponents fear expansion beyond the 18 days/year limit
- Regulatory confidence is low; binding restrictions are controversial
Critical Questions
Data Quality: How reliable is the forecast of only 18 föhn days per year? Is this based on long-term data or estimation models?
Conflicts of Interest: The airport has economic interest in higher capacity and reduced delays. Who independently verifies whether these interests skewed the noise protection assessment?
Causality of Regulation: The airport spokesperson claims the Federal Council and Sky Guide will maintain the 5% limit. What control mechanisms ensure this commitment if operational pressure increases?
Alternative Scenarios: Are there alternatives to south departures—such as landing sequence optimization or slots during föhn conditions—that cause less noise pollution?
Risk Communication: How was the crash risk over residential areas quantified? What insurance or liability rules apply to such scenarios?
Implementation Drift: Historically, air traffic shows deregulation tendencies. How will expansion of the 5% rule be prevented in the long term?
Stakeholder Balance: Were resident interests weighted sufficiently in the planning to date, or does the airport's efficiency perspective dominate?
