Shared resource management for integrated avionics systems

Increased demand for avionics system functionality has lead to $10-15M avionics suites on recent aircraft. Support costs are high due to low avionics system reliability. When required, new functions have to be "shoe horned" onto aircraft at great expense. Integrated avionics systems are being developed to address these problems. Common module, shared resource avionics systems offer the potential for controlling the cost, size, and weight of avionics while providing a 25-fold increase in system availability and growth potential. The challenge to realizing the potential of these systems is effective utilization of the avionics resources.>
