RunwayIce warning systems

Benefit – Ice warning systems» permanent control of the runway for

24h a day and 7 days a week is possible.

» flight security can be optimized

» permanent acquisition of data will optimize the winter maintenance and in special the use of deicing fluids

» help to minimize control trips and organize them more effective

Benefit – Ice warning systems» Certified acquisition of data

» Automatic backup and verification of the runway status (data) » Use in case of refund

examination

» Use of the runway status for airlines possible

System structure

Passive & active RWY sensors

Passive Runway sensor

IRS31-UMB

» Measurement principle:Passive salt concentrations- and freeze point temperature measurement by measuring the conductivity dependent on water film height

Passive Runway sensor

IRS31-UMB

Measurement of…» RWY surface temperature» RWY depth temperature in 5cm and 30cm» Water film height up to 4mm» RWY condition (dry, damp, wet, critical

wetness, critical (snow/ice))

Passive Runway sensor

IMPORTANT:No measurement of freezing point temperature in runway applications with IRS31-UMB possible because of use of deicing fluid

Active runway sensor

ARS31-UMB

» Measurement principle:Measurement of salt concentration and freeze point temperature by active cooling and heating of the sensor surface.

Active runway sensor

Measurement of…» Freezing point temperature

(independent of used deicing fluid)» Deicing fluid concentration

System structure

Only with combination of passive and active RWY sensor determination of following parameters possible:

» RWY surface temperature» RWY depth temperature (5+30cm)» Water film height up to 4mm» RWY condition (dry, damp, wet, critical wetness,

critical (snow/ice))» Freezing point temperature» Deicing fluid concentration

All-in-one weather station

All-in-one weather station

WS600-UMB

Measurement of…» Air temperature» Rel. Humidity» Dew point» Air pressure» Wind speed and wind direction» Precipitation intensity» Precipitation type
