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

Passive & active RWY sensors
![Page 6: 2012 04 24 Runway Ice Warning System](https://reader037.vdocuments.site/reader037/viewer/2022110302/54681466af795985308b46ba/html5/thumbnails/6.jpg)
Passive Runway sensor
IRS31-UMB
» Measurement principle:Passive salt concentrations- and freeze point temperature measurement by measuring the conductivity dependent on water film height
![Page 7: 2012 04 24 Runway Ice Warning System](https://reader037.vdocuments.site/reader037/viewer/2022110302/54681466af795985308b46ba/html5/thumbnails/7.jpg)
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.
