How are the wings of a mono- bi- or triplane referred to with regard to position?
While boats use port &amp; starboard, aircraft (at least in the U.S.) generally don't.  &quot;Left&quot; and &quot;Right&quot; work well for most things; when talking with flight attendants (on a large aircraft), &quot;captain's side&quot; and &quot;first officer's side&quot; serve the same purpose as &quot;port&quot; and &quot;starboard&quot; (i.e. the port or captain's side is the same side of the vehicle, regardless of whether it's on an individual's left or right at the moment).  For maintenance purposes, the engines and certain other left/right-side components are referred to as the #1 and #2 (and #3 and #4 if you have them), and when talking with a pushback crew (who are in front of the airplane facing it -- so their &quot;left/right&quot; is opposite that of the pilots) it's common to refer to &quot;the #1 side&quot; (i.e. captain's) or &quot;the #2 side&quot; (i.e. F/O's).  When we would back up the C-130, the loadmaster on the cargo ramp looking behind us would direct &quot;turn toward #1&quot; or &quot;turn toward #4&quot;, which worked out nicely.
But, I don't think I've ever heard of wings referred to as #1 &amp; #2, or really as anything other than left &amp; right.  (Those who've flown on aircraft carriers may report a different experience while at sea, I've not done that.) I'd say that the most general case would be to refer to a left/right wing, or on a biplane left upper, right lower, etc, and in a triplane, I'd have to assume left middle (or, perhaps less likely, left center) wing.
The Nav lights are generally referred to as left or right, at least in my carrier's operation.  You could refer to them as &quot;the red nav light&quot; or &quot;the green nav light&quot; but I don't think that's particularly common.
Various different organizations will have their specific conventions, but as a general case, plain (or, &quot;plane&quot;) English works well &amp; is a good place to start until the preferred local terminology is introduced.
