Abstract

An Aircraft Communication, Addressing, and Reporting System (ACARS) to VHF transceiver interface unit (AVIU) which allows direct pilot control of the VHF mode (voice or data) and also commands the ACARS into the proper mode.

Claims

1. In combination:

an aircraft communication, addressing, and reporting system (ACARS);

said aircraft communication, addressing and reporting system providing port select, voice/data, MIC keyline, and audio output representative signals;

a VHF transceiver;

an interface unit coupled between said aircraft communication, addressing and reporting system, and said VHF transceiver;

said interface unit including means for isolating said port select, voice/data, MIC keyline, and audio output representative signals between the said aircraft communication, addressing and reporting system and said VHF transceiver;

to allow the VHF transceiver to be utilized for safety of flight voice communications and for data communications in an exclusive manner.

2. In combination:

an aircraft communication, addressing and reporting system;

a VHF transceiver;

a cockpit voice/data switch;

an interface unit coupled between said aircraft communication, addressing and reporting system, said cockpit voice/data switch, and said VHF transceiver;

said interface unit including means for the operator control of said cockpit voice/data switch to provide control of the VHF transceiver mode of operation to allow the VHF transceiver to be utilized for safety of flight voice communications and for data communications in an exclusive manner.
