Admittedly, this picture is not fully realistic for two reasons. First, it's quite unlikely that the Swiss Air Rescue REGA will fly to Innsbruck. Second, they don't use the AW139 but a mix of AW109SP "Da Vinci" and H145.
Nevertheless, REGA has ordered three AW169 – which is the smaller sister of the AW139 – from Leonardo in order to provide all-weather HEMS service. As those aircraft will be equipped with an ice protection system, those helicopters will expand the operation limits for air ambulance helicopters to bad weather with icing conditions. They already do instrument approaches on hospital helipads during bad weather which I think is pretty amazing!
