Are there published ranges of recommended wingloading [oz/in^2] for the
various classes of planes (eg trainer, sport, scale)?

THX,

I don't know if there are published ranges, but here's a ROUGH stab. (I
know, I know, if it is a rough stab, maybe I should sand it before I cover
it...:))

I hope others will add their insights:

Thermal Gliders:  8 - 14oz/ft2 (As light as possible)
Slope Gliders:   15 - 25oz/ft2
Trainers:        18 - 25oz/ft2
Sport:           15 - 30oz/ft2
Pattern:          ???
Scale:           25 - 45oz/ft2

Not that I know of But here is my findings,

                      Trainers-    14-18 oz
                       Sport         14-25 oz
                       Scale         20-30oz (5-10 pound size)
                                         25-40oz (10-20 pound size)

These are ball park figures.

I absolutely concur with Gregs chart.

But there are exceptionally light or heavy planes that disobey these
general rules. For example, I have 2 semi-scale planes that have WL of
13 Oz / ft, and a high wing trainer (at least that's what I call it)  at
7 Oz / ft.

I once had a pattern plane with low drag and 27 Oz / ft, and I had a
heck of a time landing it! It would whistle by 2 feet off the ground,
and keep going almost out of sight before the wheels touched down.

My Semi-Scale Cessna Cardinal sits down any time I want, even from a
sharp descent,  at 13 Oz / ft. Wing loading can be deceptive!

        Great question.  actually I am working on a Visual Basic program that calculates weight of a plane ( using a differental  
ballance beam type scale ), and also calculates wing loading.  I also want to give an indication of low/med/hi wing loading.  IE it
would print the floaters in green, the typical sport plane in yellow, and the lead sleds in red.  I know that the range of good/nogod
changes with wing area, and span.  
        Now for the $64K question.  Is there a "set of rules"?, and if so what are they?  Any input would be greatly appriciated.  
Actuall the program is done, except for the help file.  I'm teaching myself this stuff, and now that summmer [ flying season]  is here
progress has slowed to a crawl.  I'll be offering the program to anyone who is interested as freeware when it is done though.

        THanks,
                Dave

Accourding to an article I read recently in a magazine, the 'safe' wing
loadings vary greatly with the wing size. Presumably something to do with
smaller wings being less efficient etc. The article was an argument for
larger model aeroplanes, and basically said that bigger aeroplanes could
fly at higher loadings so the structure could be more complex and more
realistic. Therefore, I think that estimates like these would need the
wingspan stated etc. Perhaps, if people posted in with the wingspan,
plane type and recommended loadings for their various planes, someone
might want to formulate a guide to wing loadings??????
