Koch chart, used by pilots to check parameters for take-off.
It is used by laying a straight edge to intersect the outer parameter scales, and reading the result where the straight edge intersects the inner scale, as shown by the diagonal line example.
A commonly used example of a generic chart, based on the same principles as the slide rule. I cannot recall the generic name (why do so many things get named after people, which gives no clue to what they are), but I have used different scientific ones and indeed designed a couple.

The generic name is 'nomograph'; see Wikipedia for some more details, including the chi squared nomograph which I used to use back in the day.

I'm not sure that the name 'nomograph' (Greek: Law line) gives any more details about what it is that the specialise 'Koch chart'.
