Canopy Lookup Tool Update
Improvements
- Added more tables (Norway, England, France, Sweden, Brian G + JS)
- Standardized Code for Output
- Select Tables to be used
- Analysis tab to look at WL progression for your current weight
Todo: Add more regulations: Poland, Spain, NZ…..
Observations
We can see Britsh and the French having a canopy for almost 50 weights [60 till 110] while Brian Germain / Sweden over-focuses on jump numbers. The latter increases higher variations as kilos go up. Norweigan way is after my opinion the best as it provide a wide range (0-2000 jumps) whilst incentivizing canopy coaching and higher licenses. Well done random country *pounds chest*.
One point to be aware of is that equal wingloading on smaller canopies may result in higher performance behavior due to shorter lines, less inertia, higher momentum and a lower pilot drag than anticipated. While all these effects might be small they can in sum have a significant effect – but it’s hard to conclude. All regulations I’ve seen so far take this into account.
Canopy Size Considerations
From USPA Manual – Part 1 | Equipment: B – Size v. Wingloading:
The next section (not shown) of the manual explains the differences in plan-forms. National regulations have requirement for when to use elliptical and cross-braced canopies exactly for the reason that these canopies pack a much higher punch than their rectangular and semi-rectangular equivalently sized canopies.
