The key is to realize how a chopper works. Simulators More crucial in Training

"When we switched to a fresh model of training, we decided to change how we teach pilots. We introduce fresh training techniques on a powerfully improved platform. This platform is H135 and H145. It is crucial not only to fly a helicopter, but besides to realize how it works, its components and systems, but besides to do as much training as possible, e.g. in a synthetic environment. For example, in the UK, there is simply a desire for 90% of flights to be performed in simulators up to 2040," says Steve Doubleday, Chief of staff Airbus Helicopters in the UK.
