Green Approach – a greener way to land

In 2006, SAS pioneered a green approach that involves landing in a way that is more fuel-efficient compared with conventional descents.

Modern aircraft can navigate and fly with great precision. SAS has used this ability to great effect in its “green approach.”

Conventional descents involve aircraft leveling out between changes in altitude. At each leveling, an increase in throttle is required and therefore fuel is burned.

The green approach, however, means that pilots can almost glide on a steady path to the ground with the engine throttle near idle. This reduces fuel consumption and carbon emissions and also lowers noise levels, benefiting people who live near airports.

The green approach is regularly used by SAS when there is a mid to low volume of traffic at airports.
