Can someone fucking explain why planes don't have some sort of emergency raft inflatable type thing underneath it in case of crashes? Or even some emergency parachute that can be deployed to slow a fall?

>>81498284 (OP)
Planes are heavy as fuck, something like that adds a shitton of extra weight so then the plane won't fly

think about it, a bigass balloon made of a resistant material plus a shitton of air to fill it up, lots of weight a lots of space equals zero reliability

>>81498284 (OP)
What kind of balloon could cushion the fall of a 500 tonne aircraft travelling at 160mph?

>>81498290
>>81498302
Scale it up

>>81498312
This would kill more people, it would arrest forward momentum while doing fuckall for vertical momentum.

>>81498312
Friday did the math and let's say for a 727, we're going to need roughly 12,000 to 15,000 ft of parachute. Also, wherever these risers are that will connect the plane to the parachute, it's not going to hold to the frame of the aircraft you would have to completely redesign the frame. I don't see that as a big deal so whatever you know what I mean? Those small aircrafts have anywhere from 250 to 500 square feet of parachute, the larger the aircraft the faster you can allow The Descent so maybe somewhere around 20 miles an hour, military parachuting is anywhere from 13 to 20 mph, and Sport parachutes are 5 to 10 miles an hour depending if they do that curling technique or whatever you call it near the ground. Now, that means for 7:27, we're talking a pair of shoe with the square footage larger than a football field. So I'm going to say multi- stage parachutes, and you can start with the type of parachutes that would only slow an aircraft going maybe 500 knots, down to like, 120 knots? And then you deploy your multi-stage parachutes and deploying them one after another will help slow The Descent without causing severe jerking of everyone inside. Don't want to end up jerking everyone off.

>>81498359
Put four on each end retard kun to keep it balanced

>>81498428
I like the idea of multi stage

>>81498284 (OP)
It's not cost effective. Any safety feature adds weight, which means less passenger seats and less sales. It would also make the planes themselves more expensive and the fewer seats would raise ticket prices significantly.

>>81498432
imagine missing the point THIS hard and having the gall to call ME retard kun. Did you even take middle school physics? If a plane needs to pop chutes, it means there has been an engine failure. Engine failure means no additional forward thrust is going into the system, while constant vertical force of gravity is. Chutes will fly out at ~45 degrees and completely arrest the critical forward momentum used for gliding the plane into an unpowered landing instead of simply falling like a 50 ton rock straight down. The sheer amount of surface area required to arrest a falling rock of that mass is simply infeasible.

>>81498470
Yeah I guess people deciding not to fly because they rather not fall out of the sky would be cheaper you're right

>>81498481
Hur dur retard kun

ITT:
a bunch of literal retards attempt to learn about aerodynamics and physics

>>81498491
wow, cool not-to-scale concept art for a parachute that doesn't even save the plane so is completely irrelevant to the question you actually asked

>>81498505
Why the fuck would you care about the plane retard

>>81498284 (OP)
how much do you think a 747 weighs you fucking tard. most planes go down over water or mountains anyway where your retarded solutions, even if they could theoretically support a plane's weight on flat terrain, would just condemn people to die horrific deaths of drowning or dropping off cliffs

>>81498509
why the fuck did you ask why PLANES don't have emergency systems to slow a fall if you only cared about the passengers fuckwit

>>81498487
I mean there might be a slight dip in sales for a month after a big crash that the media picks up. The general public has a short memory and it wont be long until they forget, while the media has them thinking about something else. It is a fairly rare thing and it surely wouldn't happen to them.

>>81498284 (OP)
It's technically feasible to create a solution that makes planes safe but your life isn't worth what it would cost.

>>81498497
I absolutely love that shirt, saved

>>81498515
Because the plane is the apparatus noone asks oh God I heard about the plane crash I hope the plane is okay

>>81498571
The average plane is more valuable than the retards inside it. If you want to save the retards all you have to do is force passengers to wear personal parachutes for the whole trip and add explosive-bolt panels along to fuselage to allow bail outs.

>>81498284 (OP)
In the case of a parachute, the greatest danger for any skydiver when parachuting is getting entangeled into their own chute when landing, especially in water. Imagine 200 passengers trying to evacuate the plane while in water but when they exit the plane, they're all trapped under a giant ass parachute and all it's wires.

That planes doesnt have any type of floatation device that can be activated might be that planes reaches 30 000 feet where the air pressure is very low and there might be a danger that any such device would explode or detonate mid air due to the change in pressure.

>>81498597
>they're all trapped under a giant ass parachute and all it's wires
Once it gets to a safe landing altitude like 20 or so feet it detaches to float away from the plane

>>81498584
>Plane nose dives into the ground
>Good thing we had our personal parachutes

>>81498610
Planes only crash if
>something else hits them
>a dei hire fucks up takeoff/landing
>the control systems completely fail
>engines fail, with often ~20 full minutes of glide time before hitting the ground
The first 3 would be fatal regardless of whatever safety shit you staple on the plane, the last there is more than enough time to ensure the passengers weren't in the plane anymore. The reason they don't bother with giving everyone parachutes etc. is very simple, it costs more to pay for the safety than it does for the lawsuits.

>>81498631
If it had something to brake the fall and cushion the impact it wouldn't fucking explode so even if someone fucked up a step an experienced pilot could maneuver into a crash landing

>>81498638
Incorrect, chutes take time and distance to deploy. Even your magical chutes effective enough to work on a flying 180+ ton brick would not save you on landing/takeoff fuckups

>>81498645
Something like this dude >>81498491
You see the inflatable on the bottom

>>81498652
>would not work on takeoff/landing
>would not work on collision
>would not work on complete systems failure
>way more expensive than the alternatives for engine failure scenarios
There is a reason major airline manufacturers make shit the way they do, you are not Einstein proposing something that nobody has considered.

>we have over half a century if knowledge in aviotics
>OH SHI-A RANDOM WHO ON A RANDOM IMAGE BOARD HAS PUT OUT THIS REVOLUTIONARY IDEA!!!

>>81498670
Considering it's not been implemented yeah I think I am compared to aviation geniuses

>>81498700
The wright brothers put planes into the air
All we are asking is to find a way to minimize them from crashing into the ground
>Ummmmm duhhhhhhhhhhh

>>81498707
Oh thank god, you are just a shitposter. Had me worried NGL.

>>81498711
Im 110% serious the fact no new safety innovation has been developed to keep planes safe from imminent crashes is a strike against the entire aviation community

>>81498481
Well, Mr retard, it's obvious you aren't using a big enough parachute. So now go fuck yourself, and quit saying retarded shit

>>81498284 (OP)
>emergency raft inflatable type thing underneath
Planes are designed to float on water. At least for a time. But when the impact is too strong, then the plane disintegrates.
>Or even some emergency parachute that can be deployed to slow a fall?
Almost all plane accidents happen during take off and landing. You're too close to the ground. A parachute won't help you.

>>81498726
you are a worthless incompetent piece of genetic filth that has nothing valuable to say or contribute to any scientific or engineering field. you will die without making a single positive impact on the world. do everyone a favor and just stop speaking to others, your input only detracts from everyone else's experience.

The plane should have some kind of deployable trampoline so when it does crash it will just bounce and land nicely on its wheels

Im an aviation safety expert me

>>81498312
There are small aircraft that have these. But as other people have pointed out, it would have to be massive and weigh a ton for any regular aircraft

Planes do have inflatable rafts for emergency landings on water. I dunno if they were ever employed in human history though, crashes are already very rare and usually only happen because all "crash plans" fail

>>81498284 (OP)
Just go back to cruisers and sea ships like God intended. If you were meant to fly you'd have wings.

Why everyone in such a hurry they're flying on a tin can? Shlomo needs you back on the office earlier tomorrow?

THEY HAVE TAKEN US ALL FOR FOOLS. THE SKY IS A FUCKING SCAM. YOU COULD BE SLEEPING ON A BED IN THE MIDDLE OF THE OCEAN RIGHT NOW AND BE READING A BOOK RIGHT NOW, BUT NO YOU'VE GOT TO BE IN A HURRY.
