Do you scale up WS and chord, or just scale up the wing SA, and use the same AR? The methods sound the same, but end up with 2 completely different results.

eg:
WS 60
Chord 13.5
gives a SA of 810 in^2

Say you want to scale it up by 1.47%:
WS 88.2
Chord 19.8
which gives a SA of 1746.4 in^2

BUT 810 scaled up by 1.47% = only 1190.7? ? ?

Which way would be correct, to give approx the same WL?
