Abstract

A digital audio warning system (DAWS) that can monitor all relative aircraft systems and provide audio for any warning that requires immediate action. Current aircraft systems only monitor their individual system. The DAWS can monitor all relative aircraft systems. The DAWS may not replace the conventional warning signals, but can be a second level of warning to the flight crew. These warnings are relative to “red flag” type warnings and are not meant to replace warnings such as traffic collision avoidance system (TCAS) or enhanced ground proximity warning system (EGPWS) warnings.

Claims

1. A digital audio warning system comprising:

one or more receivers, the receivers adapted to monitor a plurality of systems;

one or more discrete logic inputs, the discrete logic inputs adapted to monitor one or more discrete systems;

a digital logic controller adapted to receive signals from the one or more receivers and the one or more discrete logic inputs; and

a digital to analog audio converter and amplifier for delivering an audio alert to a user when the digital logic controller determines the audio alert is warranted.

2. The digital audio warning system of claim 1, wherein the plurality of systems and the one or more systems are aircraft systems.

3. The digital audio warning system of claim 2, wherein the one or more receivers include an ARINC 429 and an ARINC 571 digital receiver.

4. The digital audio warning system of claim 2, wherein the one or more discrete logic inputs include 24 discrete logic inputs, including 12—

zero to 28 volt DC inputs and 12-28 to zero volt DC inputs.

5. The digital audio warning system of claim 2, further comprising two sets of discrete logic inputs, each set including 24 discrete logic inputs.

6. The digital audio warning system of claim 1, wherein the digital logic controller monitors the one or more digital receivers and the one or more discrete logic inputs simultaneously.

7. The digital audio warning system of claim 1, further comprising computer software having program code adapted to control a processor of the digital logic controller.

8. The digital audio warning system of claim 1, wherein the one or more digital receivers, the one or more discrete logic inputs and the digital to analog audio converter and amplifier are disposed on one or more printed circuit boards.

9. A digital audio warning system for an aircraft, comprising:

an ARINC 429 digital receiver adapted to monitor various systems of the aircraft;

an ARINC 571 digital receiver adapted to monitor other various systems of the aircraft;

a set of discrete logic inputs adapted to monitor discrete aircraft systems;

a digital logic controller adapted to receive signals from the ARINC 429 digital receiver, the ARINC 571 digital receiver and the set of discrete logic inputs, the digital logic controller further adapted to process the signals to determine whether an audio alert is warranted; and

a digital to analog audio converter and amplifier adapted to deliver the audio alert to a user.

10. The digital audio warning system of claim 9, wherein the digital logic controller monitors the digital receivers and set of discrete logic inputs simultaneously.
