ALL-WEATHER FLIGHT SAFETY AND EFFICIENCY

Iceland
Published: Dec 1, 2022

HOW AN AIRPORT ON A REMOTE ICELANDIC ISLAND ENSURES YEAR-ROUND FLIGHTS USING THE
VAISALA FORWARD SCATTER SENSOR FD70

The client: Isavia
Vaisala provided: Forward Scatter Sensor FD70

THE CHALLENGE: REMOTE LOCATION, WILD WEATHER

Some airports have very few weather challenges. Others have nearly all of them.
The remote island of Grímsey straddles the Arctic Circle 40 km north of Iceland.
This Icelandic island has about 60 residents plus visitors who rely on Grímsey
Airport for transportation as well as supplies and services — especially because
ocean transport can be treacherous in this region. With only a handful of
flights occurring each week, weather- related downtime is not an option.

Grímsey Airport must operate in every kind of weather, which can occur any time
of year. Rain, snow, ice, high winds, salt and low visibility are all common
conditions here, so precise weather and visibility detection are crucial for
making accurate decisions and maximizing uptime.

Isavia, the organization who operates and maintains the airport, is tasked with
ensuring safe and efficient flights no matter what the weather brings. When it
was time to replace their visibility and present weather sensor, Isavia sought
the highest quality and most dependable solution available.

THE SOLUTION: THE STANDARD IN AIRPORT WEATHER ACCURACY

Because of their longtime experience using Vaisala technology, Isavia
confidently chose the Vaisala Forward Scatter Sensor FD70 to optimize airport
operations and ensure safe flights.

The FD70 sets the standard in airport weather accuracy, detecting 100% of
precipitation from the lightest drop to the end of the storm. As the leading
forward scatter technology for visibility and present weather, including runway
visual range (RVR), the pioneering FD70 provides constant, reference grade
performance — even freezing drizzle and rain, ice pellets, and intense or mixed
precipitation.

"Grímsey is small community with important ties to the rest of Iceland, so
inhabitants depend on Grímsey Airport for everything from imported goods to
transportation. The FD70 is critical for helping us ensure safe and efficient
flights, especially in freezing conditions."
Hjördís Þórhallsdóttir, District Manager, Isavia

Clear messages and remote performance monitoring minimize maintenance, and the
FD70’s rugged, modular design with no moveable or consumable parts can stand up
to every kind of weather.

THE BENEFIT: ALL-WEATHER CONFIDENCE

Isavia never misses a weather event, thanks to the unprecedented accuracy and
reliability of the FD70. The organization can focus on airport operations
without worrying about maintaining the sensor, which is important at this remote
location. For example, the FD70 status messages indicate when windows are
getting dirty in advance, which saves time.

The FD70’s robust design, downward looking geometry, heated window, and dirt and
salt compensation algorithm all combine to provide long maintenance intervals
and ensure reliability. Isavia can operate this crucial airport with confidence
all year round to serve this community and everyone who visits.

ALL-WEATHER FLIGHT SAFETY AND EFFICIENCY

The remote island of Grímsey straddles the Arctic Circle 40 km north of Iceland.
This Icelandic island has about 60 residents plus visitors who rely on Grímsey
Airport for transportation as well as supplies and services — especially because
ocean transport can be treacherous in this region. With only a handful of
flights occurring each week, weather- related downtime is not an option.
