Sion's 6,562-foot runway is marginal for the Gulfstream G650, so it operates weight-limited — reduced fuel or payload, crew-calculated for the day's conditions. The alpine valley approach is a further consideration. Final landing performance is calculated by the operating crew for the specific date, weather, and load.
