SYSTEM AND METHOD TO AUTOMATICALLY PRESELECT AN AIRCRAFT RADIO COMMUNICATION FREQUENCY

A system for automatically preselecting an aircraft voice radio communication frequency when operating on or near the airport surface. An extension of this invention can also be used in flight. A sensor input module receives aircraft state information and flight management system (FMS) airport identification data. An airport map database (AMDB) data receiving module receives AMDB data, including AMDB voice radio frequency data. A pre-select communication frequency processing module utilizes the aircraft state information, the FMS airport identification data and the AMDB data, for determining the next pre-select frequency. An output module provides an output signal representing the next pre-select communication frequency to a pre-select communication frequency display.
