Pilots planning VFR and business-aviation flights over Switzerland on 28 June 2026 face fresh routing constraints after the Daily Airspace Bulletin Switzerland (DABS) published its 09:00 LT update. The chart—downloadable as “DABS 2026-06-28”—lists several temporary control zones (TEMPO CTR) associated with Swiss Air-Force live-fire exercises and unmanned-aircraft trials in the Emmental and Sankt Gallen regions. Although most areas top out at 5,000 ft AGL, one restricted block east of Lucerne extends to FL 100 between 10:00 and 15:30 UTC, intersecting the preferred low-level business-jet corridor linking Zurich (LSZH) with Milan Linate (LIML). Eurocontrol’s Network Manager issued a flow-management message recommending south-bound jets file via VOGEL–ELBAX instead of the standard ZUE–BASGO sequence. The Federal Office of Civil Aviation (FOCA) emphasised that the DABS is updated at 09:00, 13:00 and 16:00 local time; operators relying solely on early-morning flight packs risk missing late-added danger areas. Skyguide’s NOTAM office reported two infringements last week when foreign-registered turboprops penetrated a drone-test cylinder near Payerne, triggering temporary airspace lockdowns and departure holds at Lausanne-Blécherette. Corporate flight departments are urged to brief crews on the rolling updates and to verify night-flight restrictions published in the 16:00 bulletin, which may include RPAS activities or VIP movement no-fly zones announced at short notice. Handling agents at Zurich and Geneva said they have increased staff on the briefing desk to help short-notice charters amend flight plans. The episode is a reminder that Switzerland’s dense mix of commercial traffic, military training and experimental drone corridors demands continual monitoring—even on ostensibly routine hops across the Alps. FOCA’s KOSIF hotline (+41 44 813 31 10) remains the definitive last-minute check before engine start.
