wing loading at higher altitudes??

[newbian 0]

Does anyone know of a formula one could use to re-calculate a wingloading based on landing field elevation MSL?

eg: the jumper's home LZ is at sea level, and a jumper is jumping a canopy loaded at 1:1.
The same jumper travels to an LZ at 6000' MSL. Although his wingloading would be the same, technically wouldn't his canopy perform the same as if it were a higher wingloading at sea level?
Or am I totally misunderstanding the characteristics of canopy flight at altitude?

I other words, Could I accurately make a correllation between canopy performance at sea level vs. canopy performance at altitudes based on/compared to wingloading?

[still not clear, but it's the best I can do right now...]
thanks,

the wingloading wouldnt change, and I'm pretty sure any "formula" you would write to indicate density altitude change would have to be pretty damn complex, cause its almost suredly not linear.

It would be like, WL(subscript 1) = regular WL
WL(subscript 2) = regular WL with a multiplier added for density altitude difference

Ah, ok, now we'll wait for practical advice that can really help you.

Don't know if there is a 'calculation' for your question.[probably,almost definately].
But in general your landings will be sugnificately 'faster' to what degree in respect to a 'Low' Level DZ and 'Wingload' i don't know!

This is VERY rough, and I have no doubt that Billvon and Quade with have a whale of a time picking holes in it...

Subtract 3% off your canopy size for every 1000ft gain in elevation/density altitude.

That's what size your canopy will feel when you get to the higher/hotter DZ until you get used to the change. In real terms, it's a downsize. Your recovery arc will change, your stall speed will be higher etc.

I jump at a DZ 5000 AMSL and temp changes can range 30 dec C between Summer and Winter.

Enjoy.
