Ground based. This doesn't exclude it having components onboard the aircraft.

And yes, fundamentally, tracking inventory and maintenance requirements is all it does. I apologize if I oversimplified the details a little too much, but I'm trying to keep things readable and not get bogged down in details, and it wasn't relevant to my point. And if you'd thought about it a little longer you'd quickly realise that it's not relevant to whatever point you seem to be trying to make either.

ALIS includes a component that is carried aboard the plane and provides telemetry. Fact freely granted.

And entirely irrelevant to the notion I was addressing. The fact that ALIS transmits information from the craft is not germane to the point that it cannot be used to affect the operability of the craft - and that's according to the people who actually use and maintain these systems. I'm not making these claims; the experts are.

But none of that occurred to you because you are so desperate to try to find some kind of conspiracy theory here. To the point where even bothering to write this reply is pointless, because I can only assume that you've decided that I'm some kind of deep cover CIA agent here on direct orders from Steven Miller.

It is fucking exhausting talking to you people. I genuinely cannot comprehend the insane degree to which any tangential detail gets fantasized and catastrophized into an elaborate work of Tom Clancy fan fiction.
