Sadism & Machochism?

The problem resolves itself to dicking around with a thermocouple probe that
puts out millivolts and then picking out the microvolt rise that indicates a
rate increase. Can it be done? Sure. Easily? Perhaps. Trivially?
Probably not.

The second problem, generated by the first, is simulating such a rise and
setting the trigger in the simulation. I'm presuming that you don't want to
sacrifice an engine to calibrate the rascal. Then the question becomes,
what rate do you want to trigger? One degree a second? Ten? A hundred?
Or what rise over what time are you interested in?

Form the problem and I'll try and come up with a solution.

Tie the engine temp to a flashing LED or maybe an audible beep. Rate of
flash/beep increases as temp rises. Thing goes crazy as it's warming
up, but a button allows you to set the "this is good" steady state. If
the temp rises after that, the beeping/flashing starts going again.
Maybe the pilot wants to just shut it off again...maybe he decides that
danger is clear and present.

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
