The Incredible E6-B!

I have some real doubts. I have people that actually have been studying it and they cannot believe what they're finding.

Me? I suggest looking for your answer on Hunter Biden's computer.

When folks approach questions or problems in a well-informed fashion and then assess that information rationally and logically, there is an extremely high likelihood of those folks arriving at the same answer. Whether folks lie about or try to hide the the truths they've found in order to sustain or grow their own profits is a different question... and why messengers oft get killed.

That's precisely why teaching, learning, and utilizing reason and logic and ethics are of such critical importance to the survival of civilization... maybe even human life on earth.

Oh, Boris. Borising only as Boris can.

You should look into slide rules as well. Magic, how well they work in doing complex calculations surprisingly accurately. An E6b is a circular version of a slide rule.

When I first studied engineering in the late 70's slide rules were just about phased out, but were still in use enough that I learned how to use one. Not sure what happened to the one I owned back then.

I don't have one anymore, but I had a bunch of slide rules many moons ago.
What I always really wanted was a Curta, but... $$$

Regardless, I find both mechanical and analog computers to be fascinating and undervalued in our society. The fuel control unit on the PT6 (and presumably many other FCUs) are amazing hydromechanical-computers, we just don't typically think about it as such because we don't really think about how it's solving a differential equation... but it is.

You should look into pressure carburetors on big supercharged radial engines, I've removed and replaced a few but I can't claim to know how they work. There's a guy, his name is Pete Law, and if you can get ahold of him he'll be able to answer any questions you might have.

I've been trying to fix an antique Narco COM 11A sitting on my desk. Still fixable, as they published schematics and repair instructions back in the stone age. This one has date codes from 1972. It was interesting (to me at least) how the frequency stability was done. Typical voltage controlled oscillator. And then individual flip flops and a counter, that divided by 64 to compare to a 3.2Mhz reference. Electronics have come a long way.

Pressure carbs are easy. They work because of witchcraft and the dark arts. Sort of like Orks in WH40K, paint stuff red to make it go faster because...well, because red things go faster.

I'm old, as part of my oral test for my powerplant cert the examiner and I studied a schematic of a pressure carburetor and I had to explain how it worked, he thought he'd thrown me for a loop when he asked about the ADI circuit. Little did he know (he knew) that I had practical experience with this sort of ancient performance enhancing tech. He also wanted me to recite the firing order of not only a 2800 but also a 4360 and explain why they were different (9 cylinder rows and 7 cylinder rows). I passed, but it was certainly a different time. I was young and my mind and body were so elastic and flexible that I felt I could accomplish almost anything, if someone asked me the same questions today they'd likely be met with a blank stare, I still know why radial engines pop off in a certain sequence but it'd probably take a couple hours for me to figure it out.

Can u imagine the price of this baby? 1,995.00 smackers

LOL
 
I need to look for my expanding square search calculator. Actually, I have two. One for ship speeds, one for aircraft speeds.
 
Here they be - i used a good budget on getting these goodies before i knew i might never need them later but its alright

the e6b was 40 usd or something, on amazon. Used both a sliding plotter and a confusing plotter. Didnt know which was better

Close up on my one and only legendary VFR flight plan, which was given with a bit of hand holding but the work is mine to claim

got my foundations on paper, kind of makes me want to keep it old school...

also if EM storms knock out the safety nets, I could plan a totally novice emergency flight plan in the area on paper

These are life and survival skills. Got the concept, now just need practice and a reason to improve
 
I love maps, and charts are printed on really high quality paper that seems to last forever. I'm pretty sure I have the exact same E6-B, any idea what that plastic ring on the top right is for? I never figured it out. That little thing is magic, I suspect if you twist it in some secret sequence it'll do you your dishes. I don't know the sequence and I currently have a coffee cup and a plate that require my attention in the sink. You've dipped a toe, jump in.

The story we were told is that military pilots had to string a lanyard through that plastic loop and wear the E6-B around their necks because if they lost it they might not make it home.

Well, If its anything like the Army and turning "crap" in....one would not want the Guv to come after ones paycheck for a $40 E6-B claiming it was $400. At Government prices, like the proverbial $1000 toilet and equaled value hammers, I'd sting the SOB around my neck so I wouldn't forget it!

Yeah I completely forgot about DXing stuff but that makes quite a lot of sense. I guess it's one of those things where being smart and diligent pays off in the long run.
