What is the difference in size between parachute laid out flat and when it is deployed?

Depends if a 'round' parachute or a 'square' (ram air) one.\n\nAssuming it is the round type it will be about half as tall as it is wide.\n\nDrop me a note if you need more info.

Clouds are flat on the bottom because of the condensation level. There is a point as you climb in altitude (not always the same) where the moist rising air reaches the dew point (saturation point) and condenses onto tiny particulate matter in the air. It's nearly flat looking because of the temperature change as you climb is nearly parallel to the ground. Sort of even. Not quite.

In zero g mass is the same, but weight is different because weight is affected by gravity. People don't actually change size except for the fact that with less gravity acting on the human body, pulling it downward, things tend to puff up a bit. I'm not sure if that's what you mean or not. Hope this helps a bit.

Its about 43560 ft^2 \nor about 208.7ft  x 208.7 ft

The size of the fuselage would depend on the size of the engine (assuming that you are trying to keep the engine in the fuselage). The wing span would primarily depend on how heavy the engine (and plane itself) was, to determine how much lift you need to get out of the wings to get off the ground.\n\nRemote controlled planes with a weight of 10lbs can lift about an additional 40 lbs of payload, if designed well. The one I am familiar with had approximately a 10 foot wingspan (length of each wing was 5ft)

The most recent time I bought pads I couldn't find my normal kind (ultra-thin with wings, the ones with 3 out of 5 circles on the package filled in) in the non-compact version, so I got them in the compact version.  The only difference between the regular and the compact version is the way they're folded.  The compact ones are folded in 6ths so that in the package they're thicker, but smaller and more rectangular shaped.  The regular ones are more square in the package and folded in 3rds.  I personally like the regular ones, but only because they feel less wrinkled up when I use them.

This is turning out to be one of the most commonly asked questions:\n\nRepost of same answer I have already given:\n\n\nReasons why not parachutes (in the order they fell out my brain, not importance):\n\n1. It takes room and time for experienced people to put parachutes on - even if folks were given vintage chest mounted parachutes it isn't a practical proposition in an emergency (what about kids, the ederly and infirm?). Also - are we expecting freefall or will there be time to hook up a static line?;\n2. Even dropping folk out of two sides of the plane, to get a significant amount of people out in a stick type drop (like WWII parachutists) would take way too long even if you don't allow for a huge number of folks freezing/freaking in the queue;\n3. Storing that amount of even chest mounted parachutes is problematic (although not impossible);\n4. Assuming you had emergency opening doors (rather than the normal ones) the depresurisation (lack of oxygen plus cold) at normal altitude would kill most folks before you could get them out. If you wait until (say) 17,000 ft you are going to have very little time in an emergency to do anything;\n5. Depresurising the aircraft will make any aircraft problem worse;\n6. perversely available parachutes might make hijack/terrorims more likely ... Google "DB Cooper" for more information;\n7. The speed of exit would make the ride 'interesting for even experienced jumpers' - imagine a giant grabbing your back and throwing you like a toy (this is from personal experience);\n8. I could mention the amount of injures/deaths due to malfunctions, bad landing, collisions (with each other ... you are very very unlikely to hit the aircraft or engines) especially if a night jump or water landing but I suppose if the failure is catastrophic enough it is better than nothing.\n\nIf I think of more I will add them. \n\n\nBottom line, although it is possible to jump from a commercial jet, even at 40,000 feet (if you have supplimentary oxygen; cold weather clothing and freefall gear [unless you want to open immediately and land sometime the following day]) staying with the plane is going to be a much better bet, whatever the situation. \n\nAs a side-note, parachutes exist for entire aircraft (mostly microlights and small aircraft but their are test versions for big jets) - I suspect the sticking point is reliability combined with economics (such parachutes take space and weight quite a bit which equals money in air transport).\n\nIn the event of a controlled landing by a large jet onto/into water the floatation devices do have a use but I am not convinced that they are there for anything other than emotional support.\n\nBlue skies =8-)

Depends if u are asking regarding rain hazard (outward) collapse,\nor packing/storage  (inward) collapse...

Tough question because a lot of the intruments stick out from the bus on booms making the entire deployed length pretty substantial.  It's dish is 12 feet across and the spacecraft bus (the non-payload guts of the thing where the gyros, computers, tape recorder and communications equipment lives)  is about half that. Most of the visble, IR and UV instruments stick out on one boom about 10 feet long, and then opposite those is the radioactive thermo-electric generator sticking out about 20 feet from the center of mass of the vehicle.\n\nFinally there are some low gain dipole plasma radio wave antennas (2 metal rods oriented at 90 degree angles to one another) and a low field magnetometer boom which is probably about 24 feet long but oriented such that it only projects maybe 12-15 feet from the edge of the high gain antenna (communications dish).\n\nThe images below show you what the beast looks like, but the second one does not show the magnetometor boom.

It varies.  Typical ones are 9X18.  Some are 10X20, 9X17...handicap are 12X18 or 12X20...\n\nSome people don't follow the regulations so you might get even more variation.

Air pressure.  It actually implodes not explodes.  There is no airpressure in the cargo holds at that height.  The key being that it was sealed.  Watch for shampoo bottles or anything like that.  I had a suitcase full of shampoo. :-(

There are many standards of paper sizes and fold them. Also for any particular size different organisation has different format.\nFor details see the links below.

Technically, it's flat, but it has a potrusion where it is separated from the vegetation at the top which looks like a point.\n\nhttp://www.vidaliaonion.org/

The technique is called LAPES -- Low Altitude Parachute Extraction System -- and is still used (though infrequently) by the U.S. Army Airborne.  It is useful for delivering large loads to a contested landing strip.\n\nThere's a terrific video out on the web that shows the misadventures of some airborne and :APES drops.  If you can find it, it is worth if for the laughs, especially the shot of the cargo vehicle that breaks free from its skid and goes free-wheeling off into the sunset!

good question. the one with air cuz it has more mass

what is the difference between the two
