Nav Light Graphic

OK, I've been googling, wikiing, and reading FAR gobbledygook all morning
and I still don't have a clear picture of what the nav light requirements
(in both azimuth and elevation) are as regards brightness.

If anybody has a point to a clear post of the brightness requirements, I'd
sure be interested in seeing it. Sarangen's article on wingtip lights is
about the best I can find, but he duplicates the alpha graph and says
nothing about the theta graph.

Jim: I found the following to have quite a bit of information regarding nav
lite intensities. FAR Part 25 sub part F and Sec. 25.1391 and beyond.


I hope this is of some use

A couple of things, Stu. One, Part 25 has to do with transport category
aircraft. Two, the corresponding sections in Part 23 (light aircraft) are
what I was referring to when I mentioned "gobbledygook" in my original post.
My hit is that they gave this section to a newly graduated engineer with a
specialty in optics and (s)he wanted to show the boss how much a good
engineer can obfuscate matters.

A simple set of graphs would make things SO much easier to interpret.

Because IDK WTF or WTF the SAE is or WTF the AS docs are.

Why do you persist in using contractions that are not commonly understood?

Why don't you just buy the AS documents from the SAE. They state the
requirements pretty clearly...

SAE is the Society for Automotive Engineers. I thought all engineers
knew that one, it is on every oil can out there.

Know what a TSO is? Read the TSO's and you find the AS documents.
