Recently I saw an ad for a furniture store encouraging me to “kickback in style”. I remember hearing that word a lot as a term for relaxation when I moved to southern California in the early 80s. Before moving, I had read that word a lot in the Chicago papers in regards to unscrupulous public…
“A guy opens his door and gets shot and you think that of me? No, I am the one who knocks!” — Walter White. Sometimes I look at my airplane the way Skyler looks at Walt in that scene. On my recent annual it was a crack in the flange of the muffler can. On the 2-4-6 side of…
Would you know the symptoms of a broken valve spring in your engine data? We’re pretty good at spotting clogged injectors and fouled plugs from their distinctive patterns. We even developed our FEVA scan for detecting burned valves. Broken valve springs can be, like the song says — as restless as a willow in a…
In our last episode, we looked at events that seem to happen randomly, versus something that breaks and stays broken. Let’s call them hiccups. I had too many for one Puzzler, so this is Hiccups Part 2. The annoying thing about hiccups is there’s no guarantee it won’t happen again. Part of you is glad…
Hold your nose and drink a glass of water. Take a deep breath and hold it. Have someone scare you. There are lots of “cures” for the human hiccups. Don’t try these when your airplane hiccups. If you could choose, would you rather deal with something that breaks and stays broken, versus something that seems…
Pilots think of ground effect as the reduced aerodynamic drag that happens under the wing to cushion a landing or help with a short-field takeoff. Analysts, who are also all pilots by the way, think of it as what happens when a poor ground connection for an engine data monitor interferes with collecting the data.…
I have written about this before, every two years since 2015, and with lots of new clients and some new services since last time, it seemed like a good time for a biennial review. The comedians are fond of saying, “Timing is everything.” I think the quality of the material is pretty important, too, but…
I’ll admit that coming up with a clever title is one of the rewards of writing a monthly article. But I didn’t spend a second trying to find a clever or arcane title for this one. I wanted it to be clear what this month’s topic is. The puzzle is which engine data parameters should…
Of all the anomalies that can quickly grab your attention in-flight, which one is second on your list? Because obviously a fire is at the top of the list. For me it’s a rough runner, but a change in oil pressure is right there with it. The IO-520-K in my Bellanca Viking settles in around…
I’m in the middle of Walter Isaacson’s new book on Nobel Prize winner Jennifer Doudna. She co-founded CRISPR which is an acronym for clustered regularly interspaced short palindromic repeats. Imagine having the tools to make humans immune to viruses or other diseases. We could eliminate baldness. And glasses. And hearing aids. And maybe cancer. All sorts…
