A single engine twin fan jetpack system (Craft) is modelled to explore its behaviour during emergency descent. This is done using numerical modelling simulations. Aviation law in relation to the craft is described. There are no specific standards for the civil certification of jetpacks (therefore no jetpacks have been certified under civil law, except as an experimental aircraft). Ways through which a jetpack or other new categories of aircraft may be certified are described. The behaviour of the craft and parachute are simulated during an emergency descent. The impact velocities for different scenarios are explored and compared to known impact velocity limits. A rudimentary model for the impact of the craft is developed which determines the acceleration on the craft. The pilot is assumed to be rigidly attached to the craft and the peak accelerations that the craft experiences are also compared to known limits. An automatic deployment system for the parachute is developed. This includes FTAs and failure rates of the selected components within the system.
