the lettering on the pilot map u refer to ? i believe i might know how too.

use the SFS extract method. this contain a dump folder in main steam/il2 folders.

in _dump there is a file in a folder parts/bob, its called aerodrome.ini , every airfield is located in here with its coordinates. im presuming that a rename there would help. but also there is a fonts folder too !!!

if you need any help just ask.

EDIT: fonts folder is located in the first Core folder, ive had a look and you will need someone who knows what they are doing with those font.tga's.

2nd EDIT. i realise you are russian with a russian version of the game. i believe maybe you should simply get the fonts folder from the english version. and or apply language packs maybe too is required. not sure Ataros.
