Q. Is this even legal? The original fonts are not yours. Do you have the right to distribute these versions?
A. Short answer: as far as I was able to research, there is nothing illegal or infringing about this collection. The raw bitmap typefaces are not copyrightable, unlike fonts in specific formats such as .fon and TrueType (which qualify as software); at least this is the case in the US, where this site is based. For a longer and far more boring answer, see the legal stuff section below.
Typefaces cannot be protected by copyright in the United States (Code of Federal Regulations, Ch 37, Sec. 202.1(e); Eltra Corp. vs. Ringer). The idea that typefaces (rather than fonts, which are computer software) cannot be copyrighted in the United States is black letter law. 37 C.F.R. § 202.1(e). Under U.S. law, typefaces and their letter forms or glyphs are considered utilitarian objects whose public utility outweighs any private interest in protecting their creative elements. However, there is a distinction between a font and a typeface. The machine code used to display a stylized typeface (called a font) is protectable as copyright. In 1992, the US Copyright Office determined that digital outline fonts had elements that could be protected as software. Since that time, the Office has accepted registration of copyright for digital vector fonts, such as PostScript Type 1, TrueType, and OpenType format files.

In 2010, Airbus initiated a research collaboration with ENAC and Université de Toulouse III on a prospective study to define and validate an “Aeronautical Font”: the challenge was to improve the display of information on the cockpit screens, in particular in terms of legibility and comfort of reading, and to optimize the overall homogeneity of the cockpit.
然後包括了 regular 與 monospace 兩種:
看 Git 的記錄已經 open source 一陣子了,拿來當 sans-serif 用一段時間看看好了...
在那篇文章的 font-family 設定是「medium-content-serif-font,Georgia,Cambria,"Times New Roman",Times,serif」,所以你會假設 medium-content-serif-font (這是 Medium 設定的 web fonts) 內沒有的字型會去 Georgia 找,然後依序是 Cambria、Times New Roman 與 Times,最後到 serif。
但在 Linux 下的 fontconfig 的設計則跟這點衝突。當你丟 medium-content-serif-font 查詢時,系統會將全系統有的字型都給你 (但是排序好),而不是只有找 medium-content-serif-font 這個字型:
