oiucheekykuntalright do any parks use physics to estimate the takeoffs and stuff for the jump or do they just eyeball it? i would guess they just eyeball it since the good jumps are often just a medium booter and a small amount of step up.big/pro events like the audi nines must use physics in order to figure out what they can build, any info on that?
also i think that parks should just use dirt for the landing and built the booter out of snow, it would make the jump building way faster
Most resort stuff is eyeballed. Always a plan for the area and relative size, style of jumps and take off. Sometimes even a angle ish for the takeoff or a general idea of how steep.
For bigger stuff and custom builds people run things through computer models and figure out how big, steep, snow, impact, etc.
Im sure some use it in the day to day but not most.
There are always surprises but you can generally look at a jump and know if it will work.
Then somebody sacks up and hits it and you get some feedback. In a jump line its pretty likely there will be at least aome minor tweaking.
Everything's come along way from a jump being blade fulls of snow dumped by the cat and then hand built with a landing that wasnt nearly steep enough.
Honestly the finished product on a lit of jumps thesee days is basically good to go. But when you'r a fussy cunt you make sure it's completely dialed.
As far as earth works. It can be great but it's not for everyone. If you build in the same spots it can save a lot of snow and time but you better be damn sure.
Problems can be everything from $$$ to forest land or being in parks. Also you lose flexibility. So really only useful for the big jumps.
Cardrona NZ has pretty extensive earth works done in the last 5 years. They even have some rail pads. Downside is thats where thigs go, period, upside is theyve had pro jump line and full parks open way before other mtns on low snow years.
Personally with bigger jumps, i never gave a fuck about movement anyway. You care that the jump works. With the medium and smaller jumps you can kind of work them in anywhere and shuffle feature around. With big jumps its more find something that works, and keep doing it.
