Ejectable flight data recorder systems, methods, and devices

A system for ejecting an ejectable flight data recorder from an aircraft in an emergency situation, the system comprising:

• an ejectable flight data recorder disposed within a launching tube, the ejectable flight data recorder configured to be ejectable from the launching tube, the ejectable flight data recorder comprising a nonvolatile memory;
• an ejection system comprising a stored energy source configured to cause rapid ejection of the flight data recorder from the launching tube when the ejection system is triggered;
• and
• a control system comprising:
• an arming controller for automatically arming and disarming the ejection system based at least in part on data received from an aircraft data bus comprising at least position data and altitude data,
• wherein the arming controller is configured to dynamically disarm the ejection system when the data received from the aircraft data bus indicates the aircraft is currently in at least one of the following two situations:
• (1) the aircraft is within a first threshold distance from a first geographic location, or (2) the aircraft is above a lower threshold altitude and below an upper threshold altitude;
• and
• an ejection controller for automatically triggering the ejection system responsive to detection of one or more of a plurality of ejection conditions,
• wherein the ejection controller is configured to detect the plurality of ejection conditions by analyzing at least a portion of the data received from the aircraft data bus.
