Runway Weather Information System(RWIS)

Features

• Reduces runway maintenancecosts

• Reduces chemical applicationbased on reported conditions

• Improves decision making andmakes critical decisions easier

• Ease of use lowers amount oftraining time required

RWIS system consists of in-pavementsensors, sub-surface temperatureprobes, and a full suite of atmosphericsensors. Data from all sensors arecollected and processed in an on-field

remote processing unit (RPU). The datafrom RWIS system provides accurate andreliable information to improve thetiming of airport maintenance deicing

applications. Deicing chemical'seffectiveness is determined bythe surface temperature and not the airtemperature.

Winter weather impacts our runways and taxiways very differently than it impactsthe atmosphere, so measuring specific runway conditions is critical. Accurate, real-time weather monitoring of the runways and taxiways is one of the most cost-effective ways to ensure safe, continuous airport operations. Vaisala Runway WeatherInformation System (RWIS) is designed to provide airport staff with criticalinformation to make informed decisions about treating, clearing, and maintainingthe airport surface.

Navigator Cloud SoftwareVaisala’s unique cloud option enhancesthe RWIS user display by adding ourproprietary IceBreak pavementforecasting model. Using the secureVaisala Cloud also provides worry-freeoperations to the airport, decreasingdowntime and eliminating the need foran on-site server.

Vaisala becomes the airport’s weatherpartner by collecting RWIS reports,remotely monitoring the system andsensors, and archiving all data in oursophisticated redundant data centers.The Cloud allows you to feel safe thatyour data is protected, and availablefrom anywhere you have internet, notjust inside the airport network atthe airport.

ForecastingIn addition to the IceBreak forecastmodel, Vaisala offers full forecastingservices. Custom forecasts are generatedfor each airport customer and are

delivered daily, including a daily outlook,24-hour forecast, and 2-5 day forecast.Meteorological Consultants are available24/7/365 for telephone and emailconsultations, and provide email,telephone, or text message alerts in caseof weather events. Vaisala’s forecastingservices are flexible and customizable tothe airport’s particular needs.

MaintenanceVaisala offers a comprehensivemaintenance program that includes:remote monitoring, 24-hour telephonesupport, onsite support for outages, andreplacement of failed components.
