The vibration system is designed with a resonance body to reproduce the typical frequencies that occur in helicopters. While motion cueing is based on the human perception model for optimum motion perception, the vibration cueing system reproduces the original vibration characteristics. Vibration cueing enhances the realism.
The instructor and the pilot communicate via an intercom system, just like in a real helicopter. Original aviation headsets are used for all involved person to provide a real sound impression.
