The Directorate of Aerospace Requirements DAR 5 is in the process of upgrading the CF-18A to maintain its technical currency over the next 20 years. Part of this upgrade will be the inclusion of a Helmet Mounted Display HMD with a Night Vision Imaging System NVIS capability. As the use of HMD and NVIS technologies in the CF-18A represent new ways of performing old tasks, it was determined essential to establish how this technology would be used and to document the flow of information in the cockpit. The Defence and Civil Institute of Environmental Medicine DCIEM has undertaken an investigation of HMD and NVIS technologies in order to provide DAR with advice on human factors issues that may arise from their use in the CF-18A. The investigation will focus on the Air to Ground role of the CF-18A as this is the most likely role in North Atlantic Treaty Organization NATO and coalition activities. The Air to Ground role of the CF-18A also presents a high cognitive demand on the skills and abilities of the pilot.This report provides a detailed description of the assumed air vehicle and presents a mission scenario based on a defined CF-18A equipment suite and the employment of the CF-18A in an operational Air to Ground environment. The results of the Human Factors HF Analysis will be used to assess the impact of HMD and NVIS technologies and the flow of information in the cockpit of the Modernized CF-18A.
