SL Safety by Su Lucas is a free aviation dingbat font made from clean, monochrome line drawings. Its helicopter symbol combines firm contours with compact mechanical detail, recalling an illustrated safety manual.
Emergency signage and training materials can use the pictograms as direct visual cues. They also suit transport games, classroom worksheets, and aviation event graphics, where the machinery becomes part of the scene rather than simple decoration. The strongest connection is to rescue, flight, and public-safety subjects.
