Plus airspeed. An airplane taxiing with its nose up isn't going to fly at 15 MPH.

I keep saying something similar. Look up the wiring diagram, understand it, and pinpoint the most likely problems that fit the symptoms. Most manuals even have troubleshooting charts to get you started, but of course they cannot cover every possible factor. Too many folks just suggest replacing...

That is true, but the difference would be small. In flight, that R182 has an attitude like this: How much more nose-up would it take to make those wheel wells start scooping air?

Non-precision IFR approaches using the ADF and a watch.

In the 1970s I got lots of time at a Telex teletype. Ours was the economy model, with no tape puncher/reader. The only reason for these things was to avoid long-distance charges. Eventually those costs came down and these machines started to disappear. The fax machine finished them off. Your...

Nope. The pitch attitude will be the same for any combination of weight and airspeed. Angle of attack and airspeed are inextricably linked. The only difference will be less drag generated by the horizontal tail when the CG is farther aft. From the Canadian Flight Instructor guide: (2) To...

On some trikes that forward drain will be at the lowest point, especially if the nose oleo isn't properly inflated.

There is this Airworthiness Directive that you should study: https://drs.faa.gov/browse/excelExternalWindow/9F87A5E42C10900C86256A410065C0CD.0001 An excerpt from it: This amendment is prompted by service difficulty reports describing engines that fail to attain rated power, run rough, or...

Remember the fresh copies? Still moist, and with that mimeogaph ink smell. Odors. Every time I see a package of Crayola crayons I pick it up and sniff it. Takes me all the way back to pre-school childhood. My favorite catalogs were the Radio Shack and Lafayette electronics supply catalogs. I...

Got to watch that. Anything that introduces any chance of movement between that cylinder base and the case is a recipe for stud failure. Guys have used RTV on the base, and blown cylinders off. In your case, there could be movement between the base and the nut, equally bad.

I restored a 1951 International pickup. It had vacuum-operated wipers, run off the intake manifold. I remember my Dad's vehicles in the 1950s having them. Had to modulate the gas pedal in heavy rain. Manifold pressure is a thing, see? My students thought it was hilarious. They were also...

I had one of these in the living room when I was at the college. It worked. We'd have students over, and they'd ask what it was and how it worked. We also discovered that pay phones could be dialed for free just by working the hangup cradle lever. For a 3, you pulled it down 3 times...

I do.

$.45 for regular, $.50 for premium. And this was in Canada, where our Imperial gallon was a fifth bigger than the US gallon. 1970. A quart of oil was maybe $.80, but I don't remember that so well.

It might be a cylinder base seal, but there are some other things, too. The Lyc direct-drive overhaul manual has this to say on page 6-21: Those shims keep the plates from resting in the radius between the cylinder barrel and base. If in the radius, they would work their way away from barrel...

A leaking sump, if the oil is coming right through it, is often due to corrosion from the inside. And corrosion from the inside is usually due to water in the sump. And water in the sump is normally caused by ground-running the engine without flying it and getting the oil temps way up to boil...

I did a lot of work on a Cessna P210 that had electroluminescent lighting of the switch and breaker panels. They were dead. Got to be careful troubleshooting them with the 115 VDC on them. I found that the powerpack was pooched, and replacing it was very expensive (of course) and getting the old...

Back to that Dirty Dozen chart: Complacency and Norms figure into this. It can be difficult to change the trajectory where the staff really don't care.

Thanks for the details. Most pilots will never get that much (I didn't) and it will likely be of interest only to meteorologists like yourself. For me as a CPL and instructor (Canadian), the basics as I described them were plenty to let me and my students know when to expect thunderstorms and...

Coal slag? Never heard of it. I have used lots of copper slag, cheap, hard, sharp black stuff. But never on aircraft parts. Way too harsh. Glass bead is much friendlier.
