Abstract
System and method for the adaptive control of VHF communications in aircraft. In one embodiment, the invention includes an adaptive communications system for an aircraft having a communications processor that accesses a communications switching model to select a preferred ground communications station. In another embodiment, a method of communication between an aircraft and a ground station includes receiving a communications switching model and determining a flight parameter for the aircraft as the aircraft navigates along a flight route and selecting a ground station based upon the determined flight parameter. The aircraft then communicates with the selected ground station. In still another embodiment, a method for compiling a communications switching model includes receiving signals from a ground station and measuring a signal strength. A preferred ground station is selected based upon the measured signal strength value.
