question on a's
so...how low of a tri-sected guy wire antenna would you jump and feel 'comfortable?'

lets keep all the other factors out of it for a sec...just a big flat open grass landing area, ideal winds etc...

Re: [milkflyrockclimb] question on a's
the lower the better. guy anchors are closer, therefore, theoretically less wire to hit!Smile

Re: [milkflyrockclimb] question on a's
Ideal winds means about 15 mph straight down the middle of the sector, at your back, so there is no chance of hitting the object. With that condition, the answer is "as low as you can get turned around in" so that you don't have to take a downwinder in the 15 mph tailwind.

Ideal winds means about 15 mph

Really? Wow. Of course we all like a tail wind but
when the winds get that peppy I don't even bother
climbing - just look for a safety meeting or beer.

Ideal winds on a tower means that the wind is strong enough that it is impossible to strike the object. Thus, wind speed must exceed the forward speed of the canopy in use. 15 mph is basically just something I pulled out of thin air to approximate that.

Overall magnitude of the wind is far less important than it's quality. The wind can easily be 30 mph and smooth enough to jump, and can equally easily be 5 mph but too turbulent for safe landings.

Re: [GreenMachine] A's
I always go to the safety meeting before the jump.

How does it affect your climbing skills?

Re: [milkflyrockclimb] question on a's
260' id be comfortable with decent wind at your back. that should be enough to turn into the wind.
220 with no winds.

winds at altitude are usually a lot stronger than on the ground. Many of us have jumped in winds high enough where we are landing straight down. It's not a problem as long as the landing area is big enough

Re: [TomAiello] A's
15mph is far above the forward speed of a properly set up BASE canopy. If you have a 180 you'll be in breaks still on opening. If you need 15mph to exceed your forward speed in brakes, you have some issues. In my experience (800+ A jumps) 5mph is plenty of wind to keep you from moving forward in deep brakes, and not much more than that in shallow. Given your loading your canopy as per Manufacture recomendations. Think of an E where there is, in most cases, NO wind helping you from moving forward.

Green Machine 15mph is great winds, no need to climb down or hit the safety meetings. As long as you have the altitude to turn back into the wind, otherwise 15mph downwind landings are tricky

Re: [vid666] A's
Winds on an A are great to have. My only A jump, winds were 15 to 20 up the wire at exit.(about 5 on the ground). The jumper before me went hand held from 650 ft, did a nice 180 and opened on heading facing the tower' ten feet away. The wind gently blew her back away from the tower.On a no wind day this would have been very bad.

I climber faster and I don't bitch.

Re: [Lonnie] A's
I was actually thinking of forward speed after you pop the toggles. That way you can make the turn as quickly as possible (because this is a low tower) without any danger of hitting anything.
Shortcut
Re: [jawbreaker] A's
"The jumper before me went hand held from 650 ft"

Why the hell would you go hand held from 650 large??? Stow that shit and smoke it low!!!!!!...........besides wires are further apart the lower you are. Must be a shitty landing area, huh?

Am I so far out of touch with low jumps. FFing a 260' A with a tailwind and in the ensuing surge, stall sequence one has enough time to turn it 180?
Can you provide a video?
Thanks in advance.
take care,

Re: [base283] question on a's
Yeah, with 15 at your back from that altitutude and a one to one and a half second freefall, seems all I can get is crosswind landing, never full 180
Shortcut
Re: [base386] question on a's
just to add... i don't typically jump in winds above 10 on the ground, which is going to be pretty close to the same speed at a low exit...

but, i freefall 250-270ft range regularly and very rarely have a problem hooking a nice 180. down towards 220ft it gets a little spicy and is generally a crosswind landing.

i do have video kicking around too.Wink

Re: [blitzkrieg] question on a's
Well, we're talking about TomA's skills, currency, and judgement- all others should be far more careful.

"Ideal" winds, on a small, guyed A at 260'? 15mph? I still can't get over that gem of advice. I would give up on virtual, online mentors if I were you and find a competant local to help you out before you get hurt listening to experts on the internet.

Re: [base935z] question on a's
We hit a 260' freestander last night; about 15mph winds, handheld and had plenty of time to turn 180.

It's perfect conditions.

Re: [base283] question on a's
Hey Space, you're not out of touch, you're just like me and think of the old days when we liked just a little more edge on altitude. Anyway, usually Joy kills me if I get involved in "discussions" since we are supposed to be so "neutral" because we issue the numbers. Well, this post looked fun since I grew up in places where we did high towers and a lot of wind. I admit, these new jumpers who will even climb off of a tower elevator to do a 300' jump when the elevator will take you to 1900', is still hard for me to understand. ANYWAY, question is about a ff from a 260' tower WITH guy wires??? If so, and you use a fast BASE canopy, no reason you can't do a 1 to 2 delay, and get a quick 180 to land. To prevent excess travel of course, get both toggles to half brakes then pull the turn side way down. Makes for a much flatter turn with far less travel towards a wire.

No problem on big towers, hell, I like 30 to 40 mph winds at top so long as:
1. The wind is not crossing a wire at a lower level, especially at opening level.
2. Ground winds are stable at 15 or less for landing.

On big towers in the midwest, floater exits facing the tower were no problem since you couldn't hit it anyway in 40 mph winds at top but you still need to be far enough from the wires to give your canopy time for a 180 to 270 opening. That is the challenge if you ff a 260' guy wired tower.
My only advice is Old Fashion,, IF the tower is higher than 260' even if it doesn't have an elevator, go up my fellow BASE jumpers. A little snivel time is always appreciated by your pilot chute, and if you do happen to have one of those rare Offheading openings, you have a little time to deal with it.
Good Luck Guys and keep my twin Brother Randy, (BASE 36) in your thoughts.

Re: [RickHarrison] question on a's
i concur, but add this...

the lower you jump from, and more importantly, the lower you open... the less you have to worry about hitting other than the ground.Smile

Re: [base935z] question on a's
really not looking for 'advice' but i wanted to see if anyone had problems with offheadings on low towers with guy wires.
Shortcut
Re: [base283] question on a's
no i dont have a vid, just going off of past jumps from a 260 ft'er. there was suprisingy a lot of time ,relativley speaking, to make heading changes. however the tailwind wasnt that strong. 3-5mph.
as far as a surge goes i didnt have a surge. i opened up popped toggles keeping them deep did a flat turn and proceded to a soft landing.
ive also turned the canpopy around 120 degrees from 160ft s/l many times. that was a lil trickier but still reasonable.
i may have vid of theses jumps if your interested ill try to dig em up.

Re: [milkflyrockclimb] question on a's

take care,

we mostly jumps As (or other similar things that let the wind through) around here, so we almost always jump with a tailwind

a few of our exits are at 260 and freefalling them stowed (one exit has no real good way to go handheld) I have always had enough time time to do a flat 180 degree turn and land into the wind

if you really want I can dig out some video

maybe the facts that I jump a vented canopy and my dbs aren't crazy deep (I can turn with my rear risers with the DBS stowed without stalling) are the things making the difference here

maybe it's because I pop the brakes and turn by pulling one toggle down further before letting up slowly to get as much flight as I'll get before flaring?
