The spraying of lime is a cost-effective method for reducing a lake’s pH levels, restoring its natural balance.
This all leads to an extremely well-organised and hardworking fleet. On average, they're able to drop some 30 loads per hour from the sling.
Along with lime spraying and forest fertilisation, this year Scandair will carry out approximately 60,000 sling loads with their H125 helicopters. With a hook lift capacity of 1,400 kg, it makes for a lot of material dropped from the air.
At an average of 700 flight hours per helicopter per year, the Scandair fleet is one of the busiest in the area – considering the company also helps out with firefighting when there’s a need. “We’re still flying the H125 after 10 years because it’s the most cost-efficient helicopter out there for these types of operations,” explained Johansen. “We have ordered 16 new helicopters in 10 years. We have a high cycle consumption, so it becomes expensive if we keep them for too long.”
The volume of work for Scandair’s seven pilots hasn’t diminished with the COVID-19 pandemic. Johansen thinks it may even grow once people are able to meet and discuss projects in person. And as long as the environment needs a boost, this niche industry may become mainstream.
