The valley does the deciding. Samedan sits at 5 600 feet with terrain on three sides, which means daylight operations only, a mountain-qualified crew and a weather picture that has to hold for the whole approach rather than the moment of landing.

Aircraft choice follows from that. Light and midsize types with a steep-approach approval handle it comfortably; anything larger is planned into Zurich or Milan with a 90-minute road or rotor transfer. We file the alternate before the trip is confirmed, not after.

Timing matters more than in most places. Mid-morning departures out of Paris or London put you on the ground before the afternoon valley wind builds, and leave enough daylight margin for a second approach if the first is discontinued.

None of this is unusual for crews who fly the Engadin regularly. It is simply a place where the plan needs to be made twice: once for the trip you want, once for the day the weather gives you.
