Remote channel swap for aviation communications
First Claim
1. An aviation audio selector device comprising:
- a first input for receiving a first audio output signal of a first communication transceiver;
a first output for providing a selected microphone audio signal to said first communication transceiver;
a second input for receiving a second audio output signal of a second communication transceiver;
a second output for providing another microphone audio signal to said second communication transceiver;
a pilot headset connection for connection to a pilot headset;
a copilot headset connection for connection to a copilot headset;
a first audio switching device coupled to selectively provide either said first audio output signal to said pilot headset connection and said second audio output signal to said copilot headset connection, or said second audio output signal to said pilot headset connection and said first audio output signal to said copilot headset connection, depending upon a control signal;
a second audio switching device coupled to selectively provide either a pilot microphone audio signal from said pilot headset connection to said first output and a copilot microphone audio signal from said copilot headset connection to said second output, or said pilot microphone audio signal from said pilot headset connection to said second output and said copilot microphone audio signal from said copilot headset connection to said first output, depending upon said control signal;
a first user-operated switch configured to allow a user to select either said first communication transceiver or said second communication transceiver for connection to said pilot headset connection and the other of said first and second communication transceivers for connection to the copilot headset;
a control circuit coupled to said first user-operated switch and said first and second audio switching devices and configured to generate said control signal to control said first and second audio switching devices depending upon a user selection set by said first user-operated switch; and
a second user-operated switch coupled to said control circuit, wherein said control signal is also dependent upon an activation of said second user-operated switch to allow said user to override said user selection set by said first switch, whereby upon an activation of said second user-operated switch said first and second audio switching devices swap between a selection of said first communication transceiver and said second communication transceiver for said pilot headset connection and said copilot headset connection.

Abstract
A device and method that allows a pilot to switch between communication and navigation inputs without disrupting the pilot'"'"'s current task. An audio selector panel has inputs for at least two communication transceivers and outputs for at least a pilot'"'"'s headset. A rotary switch on the face of the audio selector panel selects which inputs are connected to which outputs. The audio selector panel further includes a remote swap switch that is mounted in a position in which the pilot can activate the switch without removing his/her hands from a yoke or diverting his/her eyes to the switch. The activation of the remote swap switch causes the audio selector panel to switch between the communication and navigation inputs. In this way, the pilot can switch communication and navigation inputs without disrupting the current task of the pilot.
