C-130 recovery.

[velcro62]

lift is produced by the wings, thrust is needed for speed and to get the plane in a state where the wind under wings is moving at a different speed then the air on top. i forget if its faster or slower.

[vensgoj]

LoL Must be another Prop Low Oil Light coming on again. I would know I worked on that damn plane. Thank god it went to the bone yard.

[Snipe4261]

I was once on a c-130 that had an engine fail, didn't even know about it until after we landed.

[GunsOfThePhoenix]

As a last resort the C-130 can fly on 1 engine if it needs to.

[EurofighterVsRaptor]

lol@ the description "A C-130.." hehe.. maybe it's just me..

[novembercherry4]

The military needs to get new vehicles and equipment. They have stuff from the 60s and 70s still. Other countries have new stuff, and we're stuck with crap... Just an 8 year observation.

[RobertGary1]

youtube is broken

[shadowblade145]

Was it just me or did that C-130 look a little....stuby.

[humlebi50]

It's just you.

[105Raptor]

@shadowblade145 i thought the exact same thing

[94miata]

Since glider pilots don't have thrust... they have to know how to convert altitude to airspeed..... they can fly just fine without an engine....

Look up 'stopped engine acrobatics'. Guy does a loop with the engines off....

Yes Thrust will increase lift, because you have more airspeed.... but the way you say it, makes it sound like the only way a plane fly's is from thrust.

Obviously, this isn't true.

[p3rs0n42]

granted, but they have so much wing surface area, they can fly at ridiculously low speeds and maintain flight, though with slowing avionic response as speed decreases

[TwooferDebunker]

Wow. That was simply amazing.

[schumacher500]

When I first saw a model of a scratch-built c-130, i thought the guy had cocked it up, as the plane looked as ugly as my balls.

Then i saw a real life c-130, and in hindsight the model maker did a great job replicating it - as the real c-130 is as UGLY AS MY BALLS.

'nuff said.

[sanrulez68]

i didn't even notice an engine wasn't running untill the end of the video hahaha

[stebo222]

Emergency? Sort of .... I guess. The P-3 Orions that I flew in in the early 70's use the same Allison T56 engines (turned over) and ROUTINELY shut down one engine and occasionally shut down two engines deliberately to increase mission endurance. These engines produce around 5000 Lb of thrust each so there's plenty of push, even with two running. Kind of depends on the gross weigh of the plane, fuel and cargo though.

[Magician1607]

Nice when i was in Oak Harbor when I was in the Navy, one of the P-3's about crashed. They had engine problems and for some reason shut down both engines on the port side. They had to nose dive it to get the engines going again and pulled up about 50-200 ft off the ground and recovered. Of course the plane was overstressed and popped rivets and tore metal in the plane. But everyone was safe.

[thetimj]

and for the most part during the decent and the approach there not using alot of power anyway

[paulvin1206]

it's better that more engines are running than turning off the other engine to balance the thrust..pilots can deal with it..they always have emergency procedures every aircraft they are applying to have in there licence.. this work has no way for errors..

[dzill2]

Wouldent it have been safer to turn the 4th engine off and have Number 2 and 3 at full rpm and thottle?

[ryr737]

no shutting down the 4th engine would have reduced thrust thus reducing lift.

[1littlelee]

yeah the pilots would keep 4 running and just deal with asymetical lift

[RobertGary1]

The engines do not provide lift. Shutting down one engine causes asymetric thrust but not any change in lift. As angine failure is a very tame emergency though because we practice for it all the time and it rarely happens.

[yourwrong12]

Lift is produced because you have thrust, With out thrust you can propel the aiplane. The more thrust you have, the more lift that can be generate.

[RobertGary1]

Not at all. Lift is not produced by thrust.

-Robert, FAA Certified Flight Instructor

[yourwrong12]

Your dumb and anyone can write

FAA CERTIFIED FLIGHT INSTRUCTOR on there response noob.

If you dont have thrust you got no lift. Simple as that. Only way you produce lift is by doing three things.

Increase angle of attack

put flaps in

or

INCREASE AIRSPEED. In this case of a c-130 with four engines. It doesnt matter it can fly with an engine down.

go get a real certificate from the FAA.

[RobertGary1]

How much thrust does a glider have? They don't seem to have any problem generating lift. Lift is not geneate by thrust.

-Robert, FAA Certified Flight Instructor

[yourwrong12]

We are not talking about a glider moron. and gliders have to be towed to get to the altitude. They cant produce lift on there own until they are moving.

With that said, A c-130 has no problem minus an engine bc it has three others.

Go fly a single engine plane and turn it off. BC YOUR FUCKED. you wont produce enough lift to keep yourself up. SO yet again YOUR FUCKING WRONG. you need thrust to produce lift.

Go get a new certificate bc who ever taught you is dumber then you are.

[RobertGary1]

Actually gliders can continue to climb after the tow is released. We only tow them to about 5,000 feet but they often go above 10,000.

I suggest you do a google search for the "4 forces of flight" for a better understanding of how they interact. Lift is not produced by thrust.

-Robert, FAA Certified Flight Instructor

[pilotjanmanpeterpan]

I totally agree with the flight instructor because 1: he is certified.

2. flaps also generate lift

3. yourwrong12 is stupid for calling you a moron!

-Jim, Upcoming Pilot (hopefully)

Peace

[nerys71]

@RobertGary1 This is not entirely true. Propellers are quite literally spinning "wings" and they do infact generate quite a bit of lift. To be clear though your intent was correct. It is not the lift that holds the plane in the air but the lift that thrusts the plane forward. The "wings" continue to function and produce lift whether the engines are on or off. Not as well as a glider but well enough to land for sure.

[RobertGary1]

@nerys71 No, propellers may be airfoils all day but thrust does not equal lift in anyway to equate it.

-Robert, FAA Certified Flight Instructor

[nerys71]

@RobertGary1 I am sorry but you are incorrect. The thrust from a propeller LITERALLY IS the lift generated by the propeller "wings" (blades) but directed backwards instead of "up" when the "lift" is pushing or pulling you we call it THRUST when the LIFT is holding you up we call it LIFT. but the forces are identical and inseparable from each other. the exact same effect and physics is at play on a propeller and wing. This is AV101 man.

[RobertGary1]

@nerys71 You are using incorrect terminology and that is causing your confusion. Just do an internet search for "4 forces of flight".

-Robert, FAA Certified Flight Instructor

[nerys71]

@RobertGary1 I was an aerospace engineering student. trust me I know the terminology. Your still incorrect. A propeller works by generating lift. Because that lift is directing the airplane forward we call the resulting force "thrust" but it is still a wing and it is still lift. You are still incorrect.

Your also nit picking. Thrust does not always equal lift but lift DOES equal thrust.

A propeller lifts forward, Thrust. its equal

a rocket motor thrusts. there is no lift. not equal.

[RobertGary1]

@nerys71 You are having trouble with terminology. The "lift" (as only you call it) is properly referred to as "thrust"(every FAA AC publication, every training manual, FAA written examinations). The thrust produced in an aircraft does not counter gravity (outside of certain aerobatic flight), and therefore, by definition, is not "lift".

This is a critical point because many, many students mistake thrust for lift and believe that an aircraft without thrust cannot counter gravity.

[samt1337]

@nerys71 I think yourself and RobertGary1 and both correct in ways but i would just like to clear something up for others reading this. Yes the propeller is like a set of wings, however these 'wings' must have an angle of attack to generate maximum 'lift'. This is obviously known as the pitch of the propeller. Having no pitch would cause 'lift' still, but no where near as much.

[nerys71]

@samt1337 well yes and no. A propeller "IS" by definition a set of "wings" and they DO generate LIFT. this is fact. I ask robert this. Explain a helicopter. Lift or Thrust :-)

[samt1337]

@nerys71 helicopter is both, lift from the rotors would also be considered thrust as the rotor blades can be angled to give the lift a more forward direction. ?? if my understanding is correct. It is all based on physics really.

[nerys71]

@samt1337 actually its not the physics we are arguing its the USAGE of the terms. You are correct with the Helicopter its both LIFT and THRUST. Now for the next trick question.

I get in an Extra 300 max push the throttle to the wall and point the nose STRAIGHT UP until I hover. now is the propeller lift or thust?

[samt1337]

@nerys71 Ohk fair enough

There is definitely still lift present as it is at an equilibrium with gravity which allows the hover. Their strength vectors are equal. However i am going to say that there is not thrust as there is no relative motion in any direction. Although i am leaning towards thinking that thrust could be present in some way as it is a tricky question lol

[nerys71]

@samt1337 what does THRUST have to do with motion? you take your Cessna 182 into a head wind and HOVER IT. are you telling me your motor and propeller are providing NO thrust? There is only one form of propulsion I have of that produces NO lift and that is a Rocket Motor. If it has blades its producing lift.

Thrust is nothing more than a specific term to describe lift "with a purpose" not holding the plane "up" from gravity. that is all.

Its still lift. Its just lift used for a different goal

[samt1337]

@nerys71 Actually i would revise my answer as their must be thrust if a volume of air is being displaced. Thrust must be present with lift actually :p. and of course the wings are only providing minimal lift with the airflow from the prop over them. very minimal

[myles4u123]

@nerys71 neither, u get a stall, any prop aircraft which u push the nose straight up in, until as you say "hover", is not providing lift or thrust, thats why 2 seconds later you will turn earthward, im not sure if it wud happen in a jet tho, ill hav 2 ask around and find out.

[FanjitaUK2k8]

@RobertGary1 seeing as we're getting all technical here, with engines running there are 5 forces acting on an aircraft :) don't you agree?

[agentfazexx]

@thefsxandREALpilot No he's not.

[InfomaniacJack]

Well... they still do produce lift because you have updrafts and wind. You're both right and you're both wrong... and both not willing to understand the other :D

[InfomaniacJack]

Well indirectly it is, since you produce higher relative windspeeds with it...

[agentfazexx]

@RobertGary1 Why do you sign it with "FAA Certified Flight Instructor?" Anyone can say that, it's YouTube for God's sake.

[WindowsAndMacintosh]

@agentfazexx

What do you mean? Everything on YouTube is 100% true.

Bob, Air Force One Captain

[agentfazexx]

@WindowsAndMacintosh Lol.

[WindowsAndMacintosh]

@agentfazexx

Well thrust is generated by turbofan engines on 747s. Who cares about gliders?

[agentfazexx]

@WindowsAndMacintosh Lol it's funny how you "sign" each comment with "Bob, Air Force One Captain" You're a fucking moron.

[WindowsAndMacintosh]

@agentfazexx

No read what RobertGary1 does. He says- Robert, FAA Certified Flight Instructor. He's probably real but I'm just joking around becasue anybody could write something. So I write bob or Steve Hawkins, Air Force One Captain.

[agentfazexx]

@WindowsAndMacintosh Lol yeah he's full of himself. People that do that intentionally, to try and look like they know what they're talking about, obviously have no life, and the only aviation experience they have is in X-Plane or FSX.

[WindowsAndMacintosh]

@agentfazexx

Yeah. I'm waiting for some "NTSB investigator" to come in here and explain what happened in the video. lol

[agentfazexx]

@WindowsAndMacintosh That or someone signing their post as "US President Barak Obama"

[WindowsAndMacintosh]

@agentfazexx

Or

-Osama Bin Laden, Terrorist

[agentfazexx]

@WindowsAndMacintosh Even Better:

Saddam Hussein - President of Iraq.

[coryboy345]

@RobertGary1 but without thrust, you need altitude to generate lift. 

[alexjamaalstraughn]

@coryboy345 not necessarily, gliders use hot spots in the air to gain the altitude. Hot air as we all know rises and when the glider pilot finds a hot spot he circles around in that hot spot til he is as high as he wants to be.

[coryboy345]

@alexjamaalstraughn True, but hot spots aren't everywhere though, without them you need altitude to maintain speed to stay in the air, otherwise the glider will stall and you'll crash.

[Whiteeboyz]

@RobertGary1 Don't you need thrust to gain any altitude though? Gliders produce forward motion from gravity, they're in essence "gliding" not "flying", This forward motion (due from gravity) is the gliders "thrust". This in turn produces this "lift" sufficient enough for the glider to "glide". You need thrust to to fly/glide, be it from gravity or the spinning fan on the front of the plane.

[jethou1]

@Whiteeboyz I see how it might appear this way, but thrust is a force which pulls or pushes a plane directly. Gliders have no such force acting on them; they are merely using gravity to build up speed so that lift is generated from the wings. Once enough speed is attained, lift will be generated even if the glider is climbing. Speed is needed to generate lift, gliders use gravity to get speed, powered aircraft use thrust. Different force, same result!

[JPH1786]

@RobertGary1 Playing Deviil's advocate....what about a fighter aircraft, such as an F-15 or an F-16, with a better than one to one thurst ratio? I'd said the thrust is generating lift there.

[InfomaniacJack]

Well now you're just nitpicking.. If you have no wind, then indirectly lift is produced by thrust or by potential energy if you already managed to get up somehow :)

[yourwrong12]

@InfomaniacJack

Totally agree. How the fuck do you think a c-130 is going to get off the ground? Pixi dust. Hopes and dreams. Maybe your fat ass can push it. Go give your stolen Flight certificate back to the FAA. How do you honestly teach students about induced FLOW. PONDER THAT ONE YOU STUPID FUCK !!!

[94miata]

Yourwrong12.... you are a dumbass.

Lift is produced from the WING. The air flows faster on the top of the wing, than on the bottom: which creates a lower pressure on top which is less than the pressure on the bottom of the wing.

You said "With out thrust you can propel the aiplane. "

which I think you meant to write *can't* in your statement.

Thrust does not mean lift. You can generate lift, without thrust.

You know some of the best pilots in the world, were glider pilots...

[iamgreatish]

@94miata Yeah! I remember watching something and it was a 747, ALL engines were out, no thrust atal, at 30,000. And he glided it to the nearest runway. And he was in the middle of an ocean. Now, he had no lift, and he did that so, you absolutely right!

[yourwrong12]

@94miata

You might be able to if you use your magic fairies to hold the plane up. LEARN TO READ rather then insult. How does your plane stay in the air? Yes, I do agree by lift. How do you generate lift? by moving air over the wings. How do you move air over the wings. THRUST !!!!

THRUST = LIFT !!! You need thrust to produce LIFT. ENOUGH SAID, If anyone wants to message me and insult me. GO TO THE NEAREST CLIFT AND JUMP OFF IT bc you all stupid.

[OmniBlade2]

lift is produced by the air flow over/under the wing, robert is very correct. You should do some reading.

[willwoodhouse]

haha you're an idiot.... lif is produced as numerous people here have said from the airflow being faster above the wing causing low pressure. Therefore the greater the airspeed, the bigger the difference in pressure and therefore more lift is given. Without thrust though a plane can still fly cause the as long as there is still some forward momentum (sustained by gravity) there will be airflow over and under the wings generating lift. Therefore engines are not required for flight.

[RobertGary1]

Wow, the dreaded 3 engine landing.

[profmet]

This great aircraft is the one that goes in Antartic missions for many national bases.

[yankeesfan135]

what a funny lokking airplane!

[Sk8rboiAnkleBreakr]

Probably one of the most normal looking ones... THAT or I have been around them too much to tell.

[cartman204]

Nah, it is normal looking. If anything, it looks anything but odd.

[Sk8rboiAnkleBreakr]

Maybe he thinks its odd because it has an engine out or something... Ive seen a C-130 C-Land with 2/4 Engines before..

[pck3]

C-130s can fly with 2 engines and make it back to land

[FizziexFlawless]

i think it looks funny too.

[guguigugu]

it would be greatl if the entire USAF was forced to make an emergency landing.

imagine that... no more dead children half way across the globe.

[Oddjob2331]

Why would the USAF make an emergency landing for dead children? the reason why they are dead is because they are poor and live in 3rd world countries and the people cant get off their ass and get jobs.

[guguigugu]

they're dead because the USAF fuckin carpet-bombed them.

[Oddjob2331]

Isn't that kind of the point? Who cares about the poor ass 3rd world countries

[ChicagoBearsRuleNFL]

Nice job

[geterdonein01]

damn, thats scary, good job to the pilots who kept it in the air.

[fflyboy192]

Hey 4 engines are better than 2 if u lose one

[usmc0809]

Nicely done, rare to see this.

[damnpoor]

It's not so rare on these old E models.

[rorywalter]

thats the new J model

[damnpoor]

Nope. 4 bladed prop and old style a/c intakes make it an E model. J's have 6 blades and the upgraded a/c packs.

[rorywalter]

my mistake your right. just the shorter fuselage and no refuelling probe made it look like a J model
