Swiss Mountain Rating 

The training for Swiss Mountain Rating  is the most challenging and beautiful training you can do in helicopter flying. In addition, this training is probably the best training to massively improve your operational safety. Typically, this rating requires about 15 hours of theoretical training and 25 to 30 hours of flight, including landings up to 4200 m/ 14000 ft above sea level and at least 200 approaches with landing in the Swiss Alps.
At the end of the training, a total experience of at least 100 flight hours is required before taking the Swiss Civil Aviation skill test.
