I have a vinyl cutter that will do the 12" letters called for to do N
numbers but wonder if there is a TrueType font that meets the
specifications of the FAA.

That is 12" high, width 2/3 of height, thickness 1/6 of height etc.

Any suggestions gratefully relieved!

There's *undoubtedly* a face in the "Univers" family that does.

Basic characteristics you're looking for:
Style: Sans Serif (not 'Serif', or 'Decorative')
Weight: probably something beyond 'bold' -- e.g. "extra bold", "black", etc.
Size: something around '1150 points' -- type size is measured by the
distance from the top of the tallest character, to the bottom
of the lowest 'descender' (frequently a lower-case 'G', or a
lower-case 'Y'). Hight of 'normal' caps (and digits) is often
about 75% of the overall font 'size'. 12" is 867,24 pts (or
maybe -exactly- 864 pts, if one is using 'computer pointes' vs.
actual 'printers points' -- difference is precisely 72 pts/
inch, vs 72.27 for traditional printer's points. So, for a
first approximation 864/.75 = 1152 pts.
