I think that the scale on maps can vary considerably.
Usually maps are expected to be in 1/1 or 100% scale, but this depends on how the original satellite data is computed in Microdem, which is something that happens way way at the beginning of a map making process.
When you make a dem file, which is a Microdem native file type that contains height data and such things, you can choose to enter a pixel radius. The standard is given as choosing 1 pixel to equal 50m and that corresponds to what is considered 1/1 or 100% scale maps in Il-2.
Most maps, but not all are made to that scale.
Often, if a map maker wishes to encompass a large surface area, maps will be made to a smaller scale. Not only is there the risk of Il-2 not being able to load a huge sized map, but Microdem itself is sometimes temperamental concerning memory usage and will also refuse to make dem files of large surface areas.
To get around this, a map maker can choose to make the map smaller - for instance by entering 1 pixel to equal 60m or 75m or whatever they wish. Then you will get maps that are less than 100% in size, but 80%, 50%, 75% or whatever.
Conversely you can also make larger scaled maps by entering lower values for the pixel scale: for instance 1 pixel equaling 25m. Then you will have a 200% map.
I´ve made a few of these because in some instances mountain ranges look better in 200%.
So, to get back to the question, not all maps are 100%. You´ll have to try and find out if other scales were used when making the maps. Most map makers will give the scale.
