I just mistakely typed the China Clipper as an Aircraft before I realized that the type is actually for models of aircraft. Is there a type for instances of an aircraft e.g. the "Enola Gay" ?
-
The Spirt of St. Louis has been typed as an Aircraft Model as well. Any progress on a type for instances of an aircraft? Can we get the name of /aviation/aircraft_model changed from 'Aircraft' to 'Aircraft Model' so that people know they're choosing the wrong type?
-
+1 To a new aircraft type (== aircraft instance), and renaming aircraft to aircraft model.
-
Calling The Spirit of St. Louis an aircraft model isn't such a bad thing - officially it was a "Ryan NYP", but only one was made.
On the other hand, I think maybe there should be a manufacturer/model or type/model heirarchy to make it clearer.

Each aircraft has several models (e.g. Cessna has 172R, 172Q, 172P etc)
there shuold be a table for the variations or each aircaft will be "new" entry, and a new field called Aircraft brand name will be added (e.g. Cessna is the manufacturer, 172 is the brand name, and R, Q, and P are the model name)
The following fields should be available for the airplains as well:
And most important, a place to add reference (where the data is from) should be added to ALL fields (but this is something freebase should add) as a workaround, a general field called tech data references should be added (a list of strings)

These are all great ideas. Perhaps someone who has more knowledge of aircraft could jump in? ptomblin, are you still around? Interested?
-
I'm not really around much. My personal feeling is that a Cessna 172S doesn't really differ that much from a 172R, and maybe a timeline of the differences would be more appropriate.

While searching the web for info on the Rutan Voyager, I noticed that weight (dry and loaded) was one of the frequently-referenced stats. It might be useful to include weight as a property of aircraft.
-
Here's a Smithsonian page with good aircraft property names. I've excerpted some that would be useful generally.
