Pelican’s Perch

I‘ve just had the rare opportunity to fly this very rare and remarkable warbird, and I’m just busting out all over to tell all. I am still amazed that I got the chance, and it appears that I’ll get to fly it on a continuing basis. To my knowledge, there are only two flying in […]

I‘ve always liked Grumman airplanes. They range from the funky (the Duck and the Widgeon) to the awesome (Bearcat). What does that have to do with the Gulfstream? The lineage, and history. Grumman built the first Gulfstream, a Gulfstream I (a twin turboprop). Over the last 40 years the company has gone through the now-common […]

Before we get into this month’s column, a little “housekeeping.”I’d like to remind readers that my old email address (jdeakin@avweb.com) is no longer valid, as the new owners have done away with AVweb email for columnists and other staff. My current addresses are my “Old Faithful” for more than 20 years, jdeakin@compuserve.com, and my newer […]

I just had a colonoscopy, my fourth.Folks, if you have read and enjoyed any of my writings, I would beg you to read this column. Even if you haven’t. For some of you, it may the most important column I’ve ever written, or that you’ll ever read.I have a very personal interest in this, for […]

I am really excited about our newfound capability to record extensive data from real, live, running engines in real airplanes. We’ve been doing this for several years, but the data is getting more and more sophisticated, and we’re learning to make better use of it. We can now take this recorded data, quickly plot it […]

First, the usual “housekeeping.” One alert reader pointed out that I had referred to the in-flight mag check, but never explained it. Let me do that in my next column. Some of the excellent “reader responses” (by e-mail and a couple of forums) deserve mention here. Those Skydiving Airplanes First, I don’t think I’ve ever […]

My thanks to those who are patiently (and not) putting up with the many problems on AVweb for the past couple months. The new owners changed servers, changed a lot of the software, and more changes are coming. The system is extremely slow, at least for some, and the messages section where readers respond has […]

AVweb’s John Deakin has been studying, testing, and teaching about piston engines for a long time. This list is a collection of all his Pelican’s Perch columns related to piston engines. Pelican’s Perch #7:Run That Fuel Tank Dry! Pelican’s Perch #8:Go Ahead, Abuse Your Engine! Pelican’s Perch #15:Manifold Pressure Sucks! Pelican’s Perch #16:Those Marvelous Props […]

Before continuing where we left off in last month’s column, I have a little housekeeping, if I may. AVweb has very kindly allowed me to use “jdeakin@avweb.com” as my primary e-mail address for these past five years. That has worked very well. It has been very reliable and quick, and it has also allowed some […]

First, a shameless plug, and a disclaimer, so that you know where I’m coming from. I am one of three partners in the new “Advanced Pilot Seminars, Inc.” a company formed for the purpose of educating pilots in engine management. The other partners are George Braly and Walter Atkinson. We have now completed two seminars, […]
