1. An interface device, the device comprising:

  • a first input configured to receive audio signals from a microphone;

    a first output configured to output audio signals to an audio headset;

    a second input configured to receive audio signals from a mobile computing device;

    a second output configured to output audio signals to the mobile computing device;

    a third input configured to receive audio signals from an aircraft audio panel;

    a third output configured to send audio signals to the aircraft audio panel;

    a push-to-talk switch that when engaged is configured to transmit audio signals from the microphone to air traffic controllers; and

    a microcontroller configured to;

    generate a first signal path between the first input and the second output when it is determined that the microphone is receiving a first signal, wherein the microcontroller provides a second signal to the second output when it is determined that the push-to-talk switch has been engaged by grounding and un-grounding a switch located on the first signal path between the first input and the second output in a predetermined pattern; and

    generate a second signal path between the second input and the first output when it is determined that a signal level on the third input is below a predetermined threshold.
