In Norway, around 700 flights each year cannot be flown due to bad weather and poor visibility. This is about to change with the introduction of new navigational instruments and flight procedures that use satellite-based GPS technology.
Known as PROuD, this collaborative European project to improve safety in EMS missions. Airbus Helicopters is supporting PROuD with its H135, certified for highly precise instrument landing approaches in difficult terrain and weather.
Together with Norwegian Air Ambulance, Airbus Helicopters recently performed impressive test flights with the H135 in June 2015.
