The Canadian Forces Utility Tactical Transport Helicopter is a modern land aviation aircraft which is used in numerous complex roles. The core of the CH146 Griffon avionics system architecture is a BAE SYSTEMS CANADA INC (BSC) Control and Display Unit (CDU). The location and method of operation of the CDU requires extended head-down operation by the pilot in some circumstances, which has been found to have flight safety implications in the tactical helicopter environments, particularly in bad weather or when using Night Vision Goggles (NVGs). One technology that shows substantial promise to address this issue is Direct Voice Input (DVI). DVI permits the control of equipment using voice commands, and has the potential to greatly reduce the amount of time that the pilot has to direct his visual attention to controls and displays in the cockpit. BSC was tasked by the Defence and Civil Institute of Environmental Medicine (DCIEM) to develop an operationally suitable Operator Interface (OI) for the CH146 Griffon. Additionally, BSC was to perform, in conjunction with the National Research Council (NRC), an assessment of a speech recognition system during operational type missions in a Bell 412 helicopter.
