What does "Full Cowling" mean?


Cowling: the removable cover of a vehicle or aircraft engine.  
So when Deku uses One for All-Full "Cowling" (as spelled in subs), does it
refer to him removing the limiter on his power, or is it just
mispronounciation ? Shouldn't it be "calling" instead?




By using Full Cowl, Midoriya effectively uses One For All power on whole his
body, rather than focusing on specific part.

This is most probably why this skill was called "Full Cowl". But it is not
clear if author explicitly decided to use word "cowl", or rather didn't knew
difference between it and some other english words with similar meaning (e.g.
"coverage").
