Civil Airfield Buttwil (LSZU)

Buttwil (LSZU) is an attractive airfield situated on a hillside, known for its scenic location and friendly, helpful staff. The airfield operates without PPR except during winter (1 October to 1 April), when prior permission is required. Customs are available with advance arrangement, typically via the website form and a phone call at least two hours before arrival. The field has two circuits, with runway 34 in use most of the time; both left- and right-hand circuits are flown simultaneously by powered aircraft, and long finals are also common. The approach to runway 34 requires careful technique due to trees near the threshold and a short available landing distance of 495 m; the displaced threshold is not marked. The circuit can be busy with helicopters, gliders, parachuting, and nearby model flying, especially on weekends.

The grass runway condition varies: some reports note it as well maintained and well drained, while others mention it can be rough or less optimal at times; caution is advised on the grass taxiway, while asphalt taxiways and parking are in excellent condition. Fuel (Avgas, Mogas, JetA1) is available on request (PPR). Parking is organized; overnight parking is possible.

The on-field restaurant offers good food and a pleasant atmosphere but has variable opening hours. Walking routes and hiking opportunities start from the airfield, with access to the village for bus connections.

The A/A frequency is shared with Bex (LSGB), so clear use of airfield names in radio calls is important to avoid confusion. Most flight service staff speak German; English may not always be understood.

Example: landing fee about CHF 20; overnight parking about CHF 12; customs about CHF 20 per movement.
