This is probably a quick look up in the OED, but I don’t have it!
This came up in a conversation with a Swedish colleague: Why does he see “Apron” on signs at airports. Easy to answer what it means, but then why/when did the term get used for concrete paved areas?
Etymology of Apron is no problem to find on a quick lookup. However, this goes as far as the cloth protection garment meaning, but never mentions the origins of the use of the word for other things. Any ideas when it first got applied to a standing area for aircraft? My guess is probably it derived from jargon in the 1st World War.
