Although many modern commercial aircraft are equipped with multiple off-aircraft communication links, in most cases a particular onboard system is limited to using one pre-assigned link. This inefficient method of aircraft-ground communication has led Teledyne Controls to seek a flexible air-ground communication management system that performs a rule-based smart router function to dynamically select the optimal link to be used for off-aircraft communication. An embedded software program, designed to interface with Teledyne’s current products, was created to implement this important function.
