The VBS AVRS has significant advantages over similar systems, including:

Flexibility.
Numerous helicopter types are supported, and the mockup is lightweight and easily configurable and transportable.

Networking.
The AVRS can be linked to any VBS session over a local or wide area network. Up to three crew members can train in the one aircraft, and multiple simulators can be linked for practice in formation flight. The AVRS can also be linked to other simulations via DIS or HLA.

Cost.
The AVRS is made from entirely commercial-off-the-shelf hardware and software.

Air Crewmen from the ADF are being consulted during AVRS development, and in accordance with their requirements* the VBS engine has* undergone* an amount of modification, including:

Joysticks to control weaponry.
Air Crewmen have access to a joystick from within the mockup to operate weaponry mounted on the helicopter.

External loads.
The engine supports external load carrying including a simulation of rope tension.

Voice over IP improvements.
Air Crewmen will use the same toggle switch they do in a real helicopter for the intercom, however all voice communication will travel over the network. All voice communication will be recorded for inclusion in the after-action review (AAR).

Improved helicopter simulation.
The default VBS helicopter simulation has been entirely replaced by a new, highly realistic model that is configurable for different aircraft types.

Interface enhancements.
The VBS Observer is being updated to provide a range of information to the Instructor, including distance from the helicopter to objects, visual indication of impact point and collision markers when collision occurs (the normal VBS damage model has been suppressed).

Hoisting.
Air Crewmen have access to an operable winch on helicopter types that support hoisting.
