Success Stories of the Mobile Sensor MARWIS in Aviation Applications

Throughout the past years, OTT Hydromet has received numerous success stories related to its mobile pavement sensor MARWIS. It is particularly popular in aviation-based applications where it is becoming increasingly established and the advantages of the sensor are more obvious.

Four years after the initial market launch, the mobile sensor MARWIS was tried and tested on a global scale. This was around 2015. In the following years, it proved its strengths in many important projects. Airports, in particular, can take advantage of this flexible and easy-to-use mobile sensor.

The values measured offer key information relative to runway conditions and thus can influence the braking distances of aircraft approaching for landing. Additionally, the MARWIS improves the efficiency of winter maintenance, saves valuable time and preserves crucial resources.

Eindhoven Airport in the Netherlands and Faa’a Airport in Tahiti are two of the numerous airports to make us of the MARWIS.

In the Netherlands, the sensor is used to ensure that runway is usable, even under extreme winter conditions such as snow showers and iced surfaces. In contrast, in tropical Tahiti, the sensor monitors water film heights that can lead to aquaplaning.

More About the Use Of MARWIS on Tahiti Airport

Faa’a Airport, which takes its name from the municipality in which it is located, is French Polynesia’s international airport on the island of Tahiti. It is situated directly on the coast 5 km southwest of the capital of French Polynesia, Papeete.

With space somewhat limited, it only has one runway with a length of 3,420 m. Only airplanes up to the size of Boeing 747 or Airbus A380 can land there.

Between December and February, Tahiti experiences its rainy season, and during this period, there can be a greater amount of water film on the pavements. It is especially important to monitor the water film heights to prevent aircraft aquaplaning and slipping on the water during this time.

More About the Use of MARWIS in Eindhoven

In the winter of 2019, Eindhoven Airport was hit by heavy snowstorms. The Dutch Air Force was deployed to keep the runway passable, which resulted in a lot of extra work. However, with the mobile sensor MARWIS in hand, the situation was readily controlled.

Although the sensor is still undergoing a test phase at Eindhoven, it has consistently delivered satisfactory results.

On particularly bad weather days, the friction of the runway is monitored by the security staff every half hour. If there is sufficient friction, it can be used as usual for take-offs.

One of the test drives during an interview with the Airfield Manager is also available as a video report online at “The Algemeen Dagblad” or “AD” – a Dutch newspaper based in Rotterdam. There it is possible to see how wintry the conditions were on the day of the recording.
