Improved and tailored low visibility forecasts for Amsterdam Airport Schiphol

Introduction Accurate, reliable and unambiguous information concerning the actual and expected visibility conditions at Amsterdam Airport Schiphol is important for the available operational flow capacity. Inaccurate and unreliable visibility forecasts have a negative impact on safety and operational expenses. Under low visibility conditions the so-called ‘Low Visibility Procedure’ (LVP) comes in charge. Table 1 shows the different visibility categories, including ceiling, with their related capacity and flow restrictions at Schiphol. A new forecast system should enhance the quality of the decision making process under low visibility conditions at the airport.
