[QUOTE="Flyboy, post: 6857984, member: 43624"] For your example of the control surface... if you’re using a computer to process the data, you can program it with expected sensor ranges during normal operation and anything outside that limit can trigger an alert. Usually any tendency to deform is well understood by engineers, as if it’s too sensitive to that, you get “flutter”, which can and will cause prompt fatigue failure or even catastrophic structural failure. Yes, sensors like temperature or pressure or volatile hydrocarbon vapor sensors do only provide whatever data they’re designed to output, and can be as simple as a binary output, like a switch. Without context, the data is junk. But with context, with understanding of what that output represents, it’s tremendously helpful. Hell, even the data from a failing or failed sensor can be useful in understanding [I]why[/I] it failed, and by extension, what else is wrong. Case in point: there’s a single float-driven potentiometer in each fuel tank in a Cessna 172 wing. 26.5 gallons of total fuel in each tank. Pretty bog standard stuff. Float moves, signal changes, gauge or indicator on MFD changes accordingly. Simple enough, right? What does a wildly fluctuating needle on the fuel gauge mean if you’re sitting still on level ground? You might think it’s a bad gauge, or a bad sensor. But in this case, it’s a known “bug”, for lack of a better term, with the sensor design dating back [I]60 years[/I]. When full to the brim, the potentiometer is in a position where it effectively glitches and tries to indicate both full and empty at the same time. But burn a pound of gas off, and the problem goes away. [/QUOTE]
