Likely refers to sensor fusion (https://en.wikipedia.org/wiki/Sensor_fusion), which is an algorithmic process.

A 4-hour MTBF window (even for a subsystem) is terrifying considering modern vehicles like this are likely all fly-by-wire.

Don't think of it as a failure. Think of it as a garbage collection pause at subsonic speeds.

Spot on.

This article should clarify what the radar reset that they are referring to is. Integer, origin, and timing resets are a function of radar tech, and are not specifically related to something like a system reboot. This would be something like restarting a process due to bad data getting into your process from a sensor and potentially leading to a bad result from a range or trajectory.

From the quote it appears that it's 4 hours between reboots of any subsystem, not the whole plane.
