Fletchings are traditionally made from feathers (often

bound to the arrow's shaft, but are now often made of plastic (known
as "vanes").

http://www.peterlynnkites.com/news.htm Peter instructs
on increasing "vane area" in the rear. He notes in his
instruction though: "Kites are wind vanes- there needs to be more 'vane'
area towards the rear than at the front or the kite will turn against
the wind direction. "

The wing of a kite system may be considered to be a vane of the kite
system. ~ JpF

Dave Santos brings in:
"Van" is archaic anglo-gaulic for wing, as I recall my youthful
Milton-study, where we perhaps find a first reference to
aeroelastic-flutter and settling-under-power as a combined
flight-dynamics failure-mode-
From Paradise Lost:
...
|
At last his sail-broad VANs |
|
|
He spreads for flight, and, in the surging smoke |
|
|
Uplifted, spurns the ground; thence many a league, |
|
|
As in a cloudy chair, ascending rides |
930 |
|
Audacious; but, that seat soon failing, meets |
|
|
A vast vacuity. All unawares, |
|
|
Fluttering his pennons vain, plumb-down he drops |
|
|
Ten thousand fadom deep, and to this hour |
|
|
Down had been falling, had not, by ill chance, |
935 |
|
The strong rebuff of some tumultuous cloud, |
|
|
Instinct with fire and nitre, hurried him |
|
|
As many miles aloft... |
