The WEF gets underway in Davos, Switzerland from January 16–23.

On January 16, and between January 19 to 25, the airspace around Davos will be restricted within a radius of 25 NM (LS-R90).

Located 150 km from Davos, Zurich Airport (LSZH) will welcome many WEF attendees, but operations will be heavily restricted.

Engadin Airport (also known as Samedan Airport) (IATA: SMV, ICAO: LSZS), is in the Engadin valley of Switzerland, 5 km from St. Moritz. It is roughly 60 km from Davos by car.

Operational Information

All inbound aircraft are required to reserve parking in advance due to ramp congestion. Parking is expected to be tight at Zurich (LSZH), so Friedrichshafen (EDNY), Basel (LFSB), and Dubendorf (LSMD) are worth considering.

Engadin Airport is also not available as a planned alternate during the WEF period.

PPR is mandatory for flights with Y/Z flight plan to or from LSZS and is managed by the airport.

The PPR number must be inserted in Field 18 of the flight plan.

Flights within LSR90 operating under instrument flight rules (IFR) are only permitted for air traffic with departure or arrival with Z- or Y-flight plans and departures with I-flight plans via SID RONAG1E/1V.

VFR Operations

Note: The following regulations apply only to flights operating entirely under VFR and not to flights operating under IFR.

For aerodrome flights at Samedan Airfield (LSZS), SSR code 1666 must be used. A separate report to the PPR office of the Air Force is not required for this purpose. Likewise, no radio contact with MIL RADAR is necessary. In addition, an ICAO flight schedule is not required for these flights.

According to VFR SUP, a Flight Instructor (FI) must be on board for training flights. Solo flights by student pilots are not allowed.

VFR Flights in the Region (e.g. sightseeing flights)

VFR flights within the region must be applied for at the PPR office. Both aircraft and pilot must be accredited according to VFR SUP. Radio contact with MIL RADAR shall be established as far as possible.

VFR Flights From or To LSZS on Published Routes

These flights are subject to accreditation, authorisation, and ICAO flight schedule requirements in accordance with VFR SUP.

Note on PPR Permits

A PPR number issued for Samedan (LSZS) does not automatically count as a permit for flying the LS-R90. These are two independent authorisations.
