And finally, for this post, and in reference to my comment in my earlier post about why the PT2 probes were clogged with ice, but not from what most people believe … the PT2 probes were probably clogged with ice, but it was from the 160-degree water sprayed on them about an hour and 12 minutes earlier. Just enough time, in 22-degree weather, to allow the water filling those probes to freeze and provide inaccurate engine pressure ratio readings.
Now, that's pertinent to the subject of this thread. But, I'm sure the probes were frozen solid LONG BEFORE the TO roll started.
And, by the way, I would whole-heartedly support a measured acceleration method (from an INS or any other unaffected source) as you have suggested, in the hope that it would deter or reduce such accidents. The reason I don’t say “cure” such accidents, is that as long as we have humans in the loop, I believe we’ll be prone to suffer human failings.
Well put. However, the human body is better adapted to being "in the loop", with systems providing external monitoring, rather than the other way around. Don't let triple-redundant FMS fool you.
