On the Internet, my friend found this picture:
My question is how natural the expression "super clean cockpit" sounds to native speakers. What do you think?
My friend thinks this expression is awkward as the primary meaning of the word "clean" is "free from dirt, marks, or stains". I don't necessarily agree with him. Another meaning, is "simple/smooth" and here the word indicates something similar to the one in a phrase like "modern design with clean lines and a bright appearance".
The picture is made by a manufacturer in Switzerland for their fundraising campaign and a possibility is that their English is not perfectly natural.
