Raf Squadron Codes And Serial Numbers
For code letters, there was a set format, with dimensions diminishing pro rata. 48' letter/numerals were 24' wide, 6' apart, and the brush strokes were 6' wide; dimensions for 24' letters were 12', 3' & 3' respectively. When Spitfires got their dispensation to go down to a height of 20', some Squadrons seem to have kept to the other dimensions, giving the letters a slightly 'squat' appearance. For general use, I found that Univers 67, or Helvetica Medium, seemed closest. It isn't easy to find a font which has all of the curves, on capital Bs, for instance, exactly the same size, and nobody seems to do a straight figure 1, so 'I' has to act as stand-in.

Serial numbers, with a height of 8', were 5' wide, 1' apart, and brush strokes 1' wide; 4' numbers were 21/2', 3/4' & 5/8', respectively. Although not exactly dimensionally correct, due to the figures being much smaller, I still found Helvetica Medium was closest, especially as its '8' has virtually identical circles, though 7 is duff, so a butchered 'Z' stands in.

What time period and a/c type are you talking about?? Since around 1947 the RAF and RN have used a more or less standard alphabet and number set. Yes, there is a 'font' available for your computer, but it's not 100% accurate according to the specs. It's close though.
WWII stuff was pretty much all either hand painted or applied using stencils, of which the variety is staggering. How To Install Sun Explorer In Solaris 11 Training. There were almost no two airplanes alike it seems. There are no 'fonts' for those. Look closely at a lot of pics of Spits and such and you'll actually see the brush marks and uneven edges to the codes.
Lately, the RAF seem to be using Helvetica Bold, or possibly Arial (I despise Arial and all other things Microsoft). That's because they're using a computer controlled stencil cutter just like the USAF and USN. You're seeing a lot more of that kind of stuff on military airplanes nowadays than you ever did before.
