These sheets are great!
they could even be useful outside cockpits as sort of "handbook" collected document!
However, about the font "Fraktur"...
for the sake of immersion, why not use a font that screams "Nazi!" out of every single line.
Think it over...
For what it's worth, to me it's also very counter immersive.
(if anything, it is telling me "Kaiserzeit"...)
There's the historical fact that the Fraktur renaissance was very short lived in the 30s and never supported by Nazi top level. There never was a unified typewriter set, so particularly if you want to recreate a typewriter written Luftwaffe document from that time, Frakture could be seen as actually counter-immersive and near impossible. A Fraktur typewrite would be a very unlikely Luftwaffe item in any case since it was never standardised. Fraktur might be plausible as pre-print font if the base form itself is supposed to look like a pre-1941 print.
In January 1941 "Antiqua" was declared the German regular type (by Führer Order) and the old fraktural types explicitly discarded as "font of the Jews" by Martin Bormann in the executive letter. It was even forbidden to be used in official documents from that time on and even in schools "as soon as possible".
On Wikipedia is a facsimile of that
letter. Please note the ridiculous fact that the whole head and seal of the document is in Fraktur Gotic letters while the typewritten text discards this font as "type of the jews" on several occasions...
My several cents on the matter of immersion
carry on the good work!
