How old do you have to be to do a parachuting course in the ATC?
Im interested in doing a parachuting course but i dont know how old you have to be. The air cadet website didnt say anything when i looked.
Before you all say ask my CO, i want some back ground information first. anyother information would be great.
Question answered by rinfrance
Probably 18, I must say in the years of being involved with ATC and ACF I have never known anyone do it.
Gliding, flying yes but parachuting, no.
How do you spawn falling from a plane and parachuting down in battlefield bad company two?
For a 360 and i know you double tap A off a high building but i see people spawning on airplanes and parachuting down. I just got this game please help
Question answered by Erin
Not all maps have this, but on the maps that do, it will be your main starting base. Just select your main base as a spawn point, and you'll spawn in the air, with your parachute already open. Have fun!
What is the physics of parachuting? What laws are involved and the mathematics involved with parachuting?
I need to use supporting mathematical equations to show parachuting.
Question answered by oldprof
Acceleration in a free-fall descent through a gas, like air, is a = g(1 - D/W); where g = 9.81 m/sec^2 near Earth's surface, D = 1/2 rho Cd A V^2 is drag, and W = mg is weight of the parachute and the person.
As you can see, drag depends on the atmospheric density rho, the coefficient of drag for the chute Cd, and its cross sectional area A. In normal circumstances, those things can be considered as a constant that depends on systemic characteristics. So we can say D = K V^2 and see that drag varies as the square of the velocity of the air into the chute and person in the fall.
From a = g(1 - D/W), we see that a = g when the chutist just jumps from his burning aircraft because the descent velocity V ~ 0 so that D ~ 0. But as V^2 = 2a(H - h), where H is the height of the jump and h is the current height above ground, the velocity builds up and so does the drag D = K V^2 = K 2a(H - h). H - h is the distance the chutist has dropped from the aircraft.
But here's the chicken or the egg conundrum. D = K 2a (H - h) = K 2 g(1 - D/W)(H - h) or in plain words, D depends on D. The only way to solve this is through looping to iteratively find a as H - h gets larger and the chutist descends farther from the aircraft.
But we can see what happens when the drag D = W the weight of the chute and chutist. Then we have a = g(1 - D/D) = g0 = 0 and the acceleration downward ceases. At which time the chutist has reached so-called terminal velocity V0. We call it that because that's the end speed, the fall will go no faster.
And there's where the chute comes in. As D = 1/2 rho Cd A V^2, we can make D = W happen a lot sooner and at a lot less velocity v < V when A is as big as we can get it. This is why chutes open up wide, to increase that cross sectional area. Then the terminal velocity is decreased because a = 0 is reached sooner when the velocity is less than it would be without the chute. Without the chute V ~ 120 mph or 176 fps. With a chute it can be lowered to about 20 mph due to that increased cross sectional area.
Notice that weight W matters when there is drag. As weight goes up, the drag has to be greater in order to reach terminal velocity. This means the chute has to have a bigger A for a heavier person in order to land at the same terminal velocity as a lighter person.
How often does one free fall parachute as opposed to static line parachute in a parachute specific field?
...and if it is static line parachuting, could you get into detail about it?
Question answered by Kyle
As far as the Army is concerned, 99% of all airborne troops jump with a static line. The only Soldiers in the Army who jump free fall are the Golden Knights (U.S. Army Parachute Team).
The cited page goes into great detail on how static line parachuting works. In general, the Army uses static lines since they can jump from lower altitudes and have a much higher factor of safety.
How high do you at least have to be while parachuting?
like can you leap out from a 10 story building using a parachute? what is the minimum height for parachuting?
Question answered by just "JR"
Depends on the parachute your are using and of its opening mechanism.
The war type parachutes (round and relatively small) can be open BEFORE the jump (jumps from a 50m tower!).
The new types parachutes (rectangular and wing shaped) open rather quickly, and a jump from about 70m is sufficient to break your fall in a safe chute.
If the chute is folded within its bag, it takes about 4 seconds to open, then 2 seconds to break your speed. That would be 80m + 20m, or 100m minimum.
I would not try it anyway...
could i possibly make a safe parachute out of a childrens mattress?
you see, i really need to get rid of this childrens mattress. i need to destruct/get it out of reach of the government somehow....i was thinking about parachuting off my house with this old mattress. do you think itll be safe?
Question answered by Winobot
If by "destruct" you mean "get dirty and do no harm to whatsoever" and by "parachute" mean "jump off the roof with and have painfully crash on top pf me" then yes.
What would it be like parachuting one ecstasy pill?
I've never tried ecstasy, and I just bought 2 White Rhino's today for me and my buddy (He hasn't tried it either). And I usually parachute my pills. Would parachuting one pill each get us high?
Avocado, thanks for the heads up, but that did not really answer my question.
Question answered by Avocado
If you're going to do a drug like that, you should have just gotten some pure MDMA. In every batch of ecstasy pills, there is GUARANTEED to be at least ONE pill that WILL kill you.
Just hope you don't have the one that will kill you.
Edit: Fine, to answer your question; yes, you will get high. Quite possibly, you will also freak out because of the additives thrown in there. And less possibly, you will die.
Whatever happens and when you wake up tomorrow, be sure to work out to increase your adrenaline because ALL of your reserves of serotonin and dopamine will be drained and you'll be the most depressed you will ever be in your life.
Any scientists that conducted an experiment similar to a parachuting mouse?
I am conducting an experiment, training a mouse to parachute using positive reinforcement. I have to give an example of a credentialed scientist who has done something similar. I am having trouble finding that, can anyone help? His experiment doesn't have to be the same, it just has to include similar actions in the mice.
Question answered by Lex Lodge
I don't think it was mice; but the most know experiments were by a guy named BF Skinner, and one named Pavlov.
As to an animal parachute; I heard there was a country over run by rats, so they did this thing of parachuting cats in. I think it was the british goverment onto some jungle island, around the end of world war two.
Does anyone know of any good, reliable parachuting places in scotland for a beginner?
Me and a few friends want to go to scotland next summer and parachute, but we dont know where to start. we need a reliable, not to over the top or expensive parachuting place where we can jump with minimal training really... thanks!
Question answered by itllneverfly
There are a couple that I've used.
You don't say where you're coming from but you may be surprised at the prices. (around £160 for a static line jump to £250 for a tandem jump) and don't expect much help from the clubs themselves. We've been trying to organize a charity jump for 12 people and you'd think that they would be tripping over themselves to get our business, but so far, a most unimpressive response from both Stirling and Strathallan. Typical British customer service I'm afraid
How did the parachute work on the Curiosity Rover when there is no air on Mars?
No air means no parachute. As I understand, the parachute would just be like a deflated balloon when deployed. I'm just curios as to how it works. Thanks in advance.
Question answered by Richard
There is air on Mars - just not very much of it. That's why Curiosity was able to use a huge parachute (which would have been ripped to shreds on earth, and probably destroyed the rover first). Ground level Martian atmospheric pressure is of the order of 1% of that on earth at sea level, which is one of the reasons people on Mars would need space suits. (Another is that there is next to no oxygen in the Martian atmosphere. It is locked up in carbon dioxide, and in oxides in the rocks.)
Also note that the parachute didn't slow Curiosity to walking pace the way a parachute might on earth. It was still doing hundreds of mph when the parachute was ditched and retro-rockets took over again.
