SavvyAnalysis Puzzlers
Every month, Joe Godfrey, Savvy’s chief data analyst, presents captivating aviation “puzzlers” derived from real-life engine monitor data on the SavvyAnalysis platform, guiding pilots in identifying anomalies for real-time safety decisions and assisting owners in informed maintenance choices.
When the analysis team started looking at engine data about 10 years ago, we could confidently recognize the patterns for clogged injectors, spark plug misfires and detonation events. Other patterns, like broken valve springs and induction leaks, came later. Last...
The Best Laid Plans…
Scottish poet Robert Burns wasn’t a pilot – but his words are good advice for flight planning. This Puzzler is about anomalies that happened in flight. 14 CFR 91.103 directs pilots to become familiar with all available information concerning a...
The Perry Mason Moment
I was channel surfing recently and landed on a Perry Mason rerun. First of all, it’s one of the great TV themes of all time. Hats off to Fred Steiner. Private Detective Paul Drake just oozes cool with his wild...
Provocation
It’s a logical question. You see something abnormal in the data and you wonder if your powerplant management triggered or provoked what happened. I’d say about a third of the tickets I work include some form of the question. Another...
MacGyver
I never watched MacGyver. It’s not like I watched it once and thought it was junk and never went back. I just never watched it. It must’ve been on when I was busy doing something else. But I think it’s cool that...
Hiding in Plain Sight
When I taught in the classroom one of my favorite scenarios was teaching software. Typically I would introduce a concept, give examples of its application in the real world, and then show the students how to do it in the...
Sweat the Small Stuff
Years ago my wife got a set of books as a gift. It’s the series devoted to sweating the small stuff in life. I guess the gifter thought she needed help prioritizing. They’re on the bookshelf in her office still...
Succession
Judging from the ratings, I’m not the only one that just finished watching Succession. I’m an only child, and often wondered what it would be like to have siblings. Granted, it’s fiction, and granted it’s a supremely dysfunctional family, but...
Better off Without it?
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....
Engine Data Analysis for Prebuy Exams
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...
Edge Case
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...
Is Flying Safer Now?
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...
Chat GPT
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...
Declaring an Anomaly
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...
These Go To Eleven
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...
Warning Signs
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 –...
The Cycle
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...
The 80/20 Rule
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%...
Plateau
It’s always fun at Oshkosh when one of the technologies of GA makes a move after spending a lot of time on the plateau. Avgas is the latest example. For years we just pumped it and worried about the short-term...
Maverick
I’m not spoiling the movie if I tell you that one of the opening scenes of Top Gun: Maverick is a pilot swinging a wrench on an owner-flown piston-powered warbird. That may be enough to make you want to see...
Foxes and Hedgehogs
The Greek poet Archilochus wrote, “The fox knows many things, but the hedgehog knows one big thing.” I’m reminded of this when clients ask “Which engine monitor should I buy?” Savvy doesn’t endorse brands or product models, so without naming...
Shuffling the Deck
We’ve seen an increase in issues related to induction lately. Is it because many airplanes spent more time grounded because of the virus, and issues are emerging as the hibernation is ending? Or maybe it’s just that for most of...
