WIND SHEAR SYSTEMS INTEGRATION PLAN, VICON (VISUAL CONFIRMATION) RELIABILITY ANALYSIS

This study supports the system reliability area of the VICON Operational Evaluation Program. VICON is the FAA's VIsual CONfirmation system which visually confirms that an aircraft awaiting takeoff has been verbally cleared for takeoff by the airport controller. Specific objectives of the study are: evaluate system failure modes and identify critical system components, evaluate the need for concept or design modifications needed to support reliability objectives for the production system, provide inputs to the VICON maintenance and spares recommendations, and to determine the sensitivity of system reliability/availability values to design and spare parts options. It is found that the predicted availability of the VICON system as installed at Bradley International Airport is 99.94% for the seven month test period. It is also found that the number of spare parts to provide a 99% assurance that there will be no degradation of VICON system performance due to a lack of spare parts over 6 months is predicted to be sixty-three total spares covering twenty-seven different component types. Thirty percent of the spares are required for the conroller's operating switches.
