With the tube method, you have to make sure there are no air bubbles or one end of the tube will be lighter in weight than the other, then you will NOT have level.
Try in a few modern Sextant they spirit level (they spirit fluid so does not freeze) No a modern nuke Aircraft carry is using a water for navigation. Aircraft use spirit level or mercury (no horizon )

How about Jonhy come lately
Radio Compass and E6B.
. Lessthan 150 years.
Any ever use one ???


Dave
 
Never used any but it would be fun to learn how
Maybe most do not know what radio compass or E6B
I think there would be more respons


E6B is a aircraft Dead Reckoning computer. It would with ground speed direction to point the aircraft with cross wind and more


The radio compass was for per-runner to GPS . Basically it points to radio station on a given frequency. Now few did talk the one for ships by different name.

OR I could toldly wrong again

What do you think ?

Although they're often referred to as a flight computer, in fact, the E6B is nothing more than a fancy circular slide rule typically made of sheet aluminum; photo below.

Your description of the radio compass is fairly accurate, I will only add that the radio stations (way points) the radio compass points to are ground based and are scattered across the US. Sometime back in the 70's (I think) avionics companies developed the R-Nav which would pick up multiple way point stations and tell the radio compass to display a heading to your destination instead of to the way point. R-Navs were the forerunner to GPS. Those of us who got our US pilot licensee back in the 80's were still required to learn how to navigate using way points and radio compass,...no R-Nav and no GPS allowed.
 
E6B did a lot with this side rull. Back 1960's every pilot had one or more. It is still amazing they designed the E6B with only a slide rule , paper and drafting board in 1930s

The radio compass dates back to 1920s ith Morse code radio station.
In 1930s and 1940's the used AM radio stations sometimes had to wait for call sign to see if had correcte station.
I still like radio compass
Some aircraft owners had two for triangulation.
Most just did with on radio compass still could do triangulation by switching back and forth.

My first generator I rebuilt was Kholer 5kw 4 cylinder water.
It was 7½ kw under the name plate. It was 240 volt 2 wire.
Hard to use but when built it they just did not add the center Tap but rebuilding found the center Tap. I use for over 30 years till walk a way. It was hard to move about 1,200 pounds was my guess.
