Deployable data recorder systems for aircraft

A system comprising:

• an aircraft;
• and
• a plurality of deployable data recorder systems coupled to the aircraft, wherein each of the plurality of deployable data recorder systems is located at a different location of the aircraft, and wherein each of the plurality of deployable data recorder systems comprises:
• a body that includes a chamber;
• a buoyancy ring coupled to the body;
• a battery located in the chamber;
• a transmitter, wherein a portion of the transmitter is disposed within a recess of the body;
• and
• a processor located within the chamber and coupled to a memory device, wherein the processor is configured to:
• receive a signal indicating detection of submersion of the aircraft in water;
• send a signal to switch a power source from the aircraft to the battery;
• send a signal to cause inflation of an inflatable bag;
• and
• cause the transmitter to send a data transmission.

A method of use of a deployable data recorder, the method comprising:

• receiving, at a processor in a chamber of the deployable data recorder, flight data associated with an aircraft via a releasable connector;
• sending, from the processor in response to detection of a submersion of the aircraft in water, a signal to switch a power source from the aircraft to a battery;
• sending, from the processor in response to detection of a submersion of the aircraft in water, a signal to cause inflation of an inflatable bag of the deployable data recorder;
• and
• causing, via the processor, transmission of a data transmission via a transmitter in the deployable data recorder.
