Good for her. Pissed me off too!

I recently had to debug a charging-circuit problem on my 170. My Zeftronics alternator controller was not the problem, but I found the data I downloaded from their website to be most helpful in figuring it out. Many companies aren't as good at making their technical information available as Zeftroni...

Thanks, George. I appreciate this, although it's mostly what I already knew. I'm still concerned about the field induced by the ground path, which isn't wires -- it's the metal structure of the airplane. Mostly I wanted to know if it's common in 170s to find that turning on the landing light (or tur...

I don't use the landing/taxi lights exclusively for landing. I first noticed this on departure from an airport -- I had the lights on to help incoming traffic see me, and while trying to establish my course I noticed my carefully-set DG wasn't agreeing with the compass. Turned off the lights, and vo...

I'd be curious about your landing light/strobe switches and/or wiring routing. I have not experienced any differences with the lights on or off. I'd get up under the panel and have a good look at how things are routed relative to the compass location. Also, check the condition of the wiring (old, c...

All compass swings should be with all exterior lights on and aircraft in flight attitude. Radios on. Engine running. I put my tailwheel on a rolling work bench (tied on) and pull it around the compass rose with a trusted person(my wife) holding the brakes. Takes 3 people this way but works. 3rd per...

My compass swings about 10 degrees when I turn on the landing lights. Is this expected? The strobe light also "adjusts" the compass, but that's on all the time so it's not so much of a problem. My compass is mounted on top of the glare shield. Landing lights and strobe are grounded to the ...

Thanks for the answers, everyone! I found the references. It turns out that the numbers for the 170 are the same as for early 180s, except for one measurement that differs by a negligible .01". My tires are larger than stock, so I'll play with it using George's recommendations, and make myself ...

You'll probably think I'm some kind of anal to ask this, and you might be onto something. :) How do you set the landing and taxi light angles on a 1955 170B? I have the 100 Series Service Manual for '62 and prior, and page 17-18 has a chart that includes measurements for early and late 180s. Is one ...

My owners manual (an original) says the following: "Cruising: Any cruising r.p.m. between 2200-2450 (green arc on the tachometer) may be selected. The recommended cruising r.p.m. is 2450...." George, Do you understand Cessna's or Continental's reasons for specifying these limits, and why ...

A couple of years ago I heard a talk given by Darryl Bolduc, a widely respected engine overhaul shop operator in the Twin Cities. He was discussing leaning technique, and how to avoid mixture settings that lead to exhaust valve deterioration. He said that at higher power settings, this is a matter o...

This is good! But it there's always one more poster who brings up Hitler and the Nazis, signaling the end of the thread. (Godwin's law: http://en.wikipedia.org/wiki/Godwin's_law ) :lol: Observant mathematicians will see lurking in the above post a proof, by induction, that it takes an infinite numbe...

Well, that's a good point. An air cleaner that breathes better might be right for operating on skis in the winter, when the dust level is down anyway.

The Challenger web site says "From the drag strip to the air strip...." If you're racing, aren't you willing to rebuild your engine frequently if it gives you a winning edge? I'm not racing my airplane, I'm going for maximum engine life between overhauls. I'm willing to sacrifice some airf...

I fly my 170 with an EI engine analyzer. I notice that whenever I change the throttle setting, the EGT changes: more throttle, higher EGT; less throttle, lower EGT. This makes sense, because EGT is a direct indicator of power. While leaning my engine, the first cylinder to peak is #5, typically, abo...
