Most of the time engine data is an important tool for helping us with powerplant management during a flight, and choosing efficient options when maintenance is needed. If you’re a regular Puzzler reader, you’ve seen lots of examples of that. But every once in a while, the data is so erratic or mysterious that it…
In a prebuy exam, the logbooks are the most important item to review. If the logbooks check out ok, reviewing a set of borescope pictures is a good next step. If there are no dealbreakers so far, take a look at the engine data – at least for the last couple of years. When a…
After ten years of reviewing engine data, it’s getting harder to hit us with something we haven’t seen before. This month we had the usual contingent of clogged injectors, weak spark and induction leaks. But we had a few scenarios that caused some head scratching, speculating and postulating. Since day one, our goal has been…
As Savvy Analysis turns ten, I thought I would try and see if the data shows that more engine monitors and more data analysis over the last ten years contributed to fewer accidents attributed to mechanical failure. You would think so, right? Engine data should make it easier to recognize problems, and knowing what the…
When we started Savvy Analysis Pro ten years ago, we wondered how long it would take before deep learning and artificial intelligence would take over and push the human analysts to the curb. In those ten years, we’ve rolled out Report Cards, Trend Analysis, reports, and three iterations of FEVA reports. Ten years ago we…
Chapter 6 of the AIM covers emergency procedures, including the difference between distress – like fire, mechanical failure, oil on the windscreen, or structural damage – and urgency – like being lost, low on gas, encountering dangerous weather, or any other condition that could adversely affect flight safety. And 6-1-2 ends with “Pilots who become…
Good news! They’re making Spinal Tap 2, with plans to release it in 2024 – 40 years after the first one. Of all the great quotable lines in ST1, it’s hard to top “these go to eleven”. Sometimes we get a set of screwy engine data that makes us wonder if the data came from…
A lot of analysis requests begin with “Something bad just happened and we had to divert and land. Is there something in the data that would’ve told us this was about to happen?” Our first reaction is usually relief – that the pilot got on the ground safely and is able to make the request.…
Baseball has the cycle – single, double, triple and home run. What would that be for an analyst working a shift? Clogged injector is probably the single. Bad spark plug is probably the double. Let’s say the triple is a stuck valve. And the homer is a detonation event. How about a catastrophic part failure?…
Apparently the 80/20 rule is also known as the Pareto Principle. Broadly applied, it means that 20% of your activities will account for 80% of your outcomes. In my previous careers in advertising and education, I would contend that 80% of stuff I spent my time on were caused by 20% of my ad clients…
