SYSTEMS AND METHODS FOR CHANGING VHF DATA RADIO MODE DUE TO ELECTROMAGNETIC INTERFERENCE

Abstract:

Techniques for detecting the presence of interference in a channel of a VHF data radio are provided. Upon detecting a sufficient level interference, the mode of the VHF data radio is changed from VHF data link (VDL) mode 2 to VDL mode A. Optionally, the VHF data radio mode may be changed back to VDL 2 from VDL mode A departing or preparing to depart.
