How to Fly an Airplane : How to Do a Power Off Stall in an Airplane

[PhysicspilotHD]

Check: Now, I want my license!

[pmitko]

He didnt control yaw that well... the nose swayed to the left as he applied full power. Not sufficient right rudder

[atnj2011]

overall... nice video, except for the comment "eventually the plan will stop flying". This is, obviously, not the case.

[SgtToughLove]

@atnj2011 What he means, is...what he has done is stopped the forces that maintains flight, when a plane stalls it is no longer flying. It is falling. Hence the stop flying comment.

[atnj2011]

@SgtToughLove yes, but that is incorrect. when the plane is stalling it is still flying. part of the wing(s) has lost lift... though not the entire wing. it is descending but it is still flying.

[atnj2011]

overall... nice video, except for the comment "eventually the plan will stop flying".

[amandavansickle]

Dave Pressey makes this ez to understand. I have learned a lot just from watching his videos. Thank You

[MetalSonic150]

Wanna know what's really fun? Keeping it in that stall, just letting the plane fall. It's like a rollercoaster and it's awesome!!!

[hurlingstar1]

@MetalSonic150 Yes,but can you get it out of the stall? Do'h =D

[faysalbest1]

I felt like i was in there and i was scared a bit :D I have a freking test tomorrow :'(

[solteria14]

@faysalbest1 same way I felt. Same way I feel watching all these videos.

[Vyppaaa11]

I'm going for my checkride wensday and this video totaly helped me...NOT! This is why expert village sucks!!!!!

[MrAlexcastro2367]

The scariest thing i've had to learn in flight school.

[multisyncxp]

@MrAlexcastro2367 lol spins was 'scarier' but more fun :)

[MrAlexcastro2367]

This was one of the scariest things i've had to learn.

[gilipichiairways]

So dont break the stall just add power? Lots missing in the explanation.

[multisyncxp]

@gilipichiairways adding power would break the stall (depending on AOA) basically your reducing your AOA w/ the air thus breaking the stall; nose drops auto (well u let it fall)

[Crashboy1024]

The way he explains how to get out of a stall is a very dangerous thing. If you don't stabilize the airplane before you add power, you could potentially enter a spin. So you turn a mild situation into a very dangerous one. The proper way to get out of a stall is to follow the airplane with the stick (if nose drops, push on the stick, if a wing drops, bank the stick towards it). After you regain control, then you add power and pull back on the stick.

[multisyncxp]

@Crashboy1024 wow talk about dangerous. if a wing drops the WORST thing you can do is correct it w/ the stick. use rudders. remember ur training if u've had any...

[Crashboy1024]

@multisyncxp If you would have read what i said with any interest, you would have understood that i didn't say to correct it with the stick. I said to 'follow' the airplane with the stick. If the nose drops, push on the stick (not pull). That way you help air flow over the control surfaces.

[multisyncxp]

@Crashboy1024 unless i mis-read some how; this is what i'm refering to. "airplane with the stick (if nose drops, push on the stick, if a wing drops, bank the stick towards it). " to bank the aircraft is to correct with the stick. you are correct (to a point) with your coment; however you break the stall then pull up slowly.

[JIMMYLINE]

@Crashboy1024 I agree with you. Don't pay any attention to "multisyncxp." He isn't even a pilot. He's a kid who is a student pilot. Read my thread with him and you'll see what I'm talking about.

[HDaviator]

Why does expert village do these videos? as if any person learning to fly would actually use this as training material.

[kd4adv]

I fly a Tecnam P2004 LSA out of Chesterfield County, Virginia - (FCI) , and I do these all the time. I've gotten used to them. I am in the process of getting my license/certification to fly. I need to work on the Emergency Landing part more. The other parts I am good at.

[theChaseGroup]

You didnt say anything about adding flaps at the beginings of your video...

[SamUKest89]

i would love to fly, but that would be pretty scary imo!

"the wing is at such an angle that it no longer produces lift"

???

jeez I'm worried about what he's teaching his students

[denhou1974]

You disagree? The wing no longer produces lift when the angle of attack reaches critical angle. So Dave is right.

[bounceferret]

@denhou1974

The wing is still producing lift mate, just not enough to sustain level flight. @ 16 degrees AOA you are producing the maximum possible lift, an increase or decrease in AOA will result in less lift. Dave is wrong

[denhou1974]

@bounceferret

As a pilot I really only care if the wing is producing enough lift to overcome the weight of the plane. I think It's safe to say that a stalled wing isn't producing lift. IMHO It's okay to tell a beginner pilot or the audience of this video the same. An aeronautical engineer not so much.

[dabois85]

@bounceferret , Ok so im guessing you actualy check that for this plane model and make yes?? as very plane is different as every airfoil is different. so say 16* AOA im guessing you mean for this particular plane..

[bounceferret]

@dabois85 Yes it's a c 150 series... critical angle is approx 16-17 degrees....most planes regardless of type or make have a stalling angle very close to this value... most certainly in light trainers (warriors, c150, 172 etc etc)

high performance military aircraft have stalling angles anywhere between 20 degrees to well over 40 degrees....

[Deej1188]

I got to ride along on my friend's flight lesson in an Archer Arrow. They did a couple of power off stalls and from that moment on, I realized I could never be a pilot.

[CrazyDoug17]

ohh okay no problem LOL:D

[CrazyDoug17]

Okay soo you say you got into your YT acount? What you mean? LOL

[CrazyDoug17]

YT?

[CrazyDoug17]

Do I and how do i do that?''Turning yours down'' I think its making some interferance with mine''

[Grazydine]

Flying is the hardest most draining thing i've ever done....The day i got my pilots license i had the worst headache of my life..

But damn was it rewarding...!

[biggestMetallicAfan]

@Grazydine Wait till you get your ATP if your aiming that way.

[chestateegold]

you ugly, now stop spamming

[ateamga]

Flying looks like a lot of fun. I really think I'm ready to fly a plane after watching this video I don't care how many 'fake internet pilots,' give me negative comment ratings!!!

[denhou1974]

It is fun. Read as much as you can and watch as many videos as possible. Ignore the know-it-all tubers and sim boys.

[ateamga]

I'm ready to fly after watching this video!

[flyingtoaster13]

Well...uh, good luck with that...

[CrazyDoug17]

@ateamga what on flight simulator?

[ateamga]

No I don't care about how many 'internet critics,' downplay my ambitions. I wannabe a pilot after watching this video.

[CrazyDoug17]

@ateamga: Dude were not stopping you from following your ambitions, well im not, thing is your not going to be ready to fly after you seen this video LOL ohhh noooo, their alot more into this than you think man LOL! But since you changed what you said previously then yeah good choice, i wouldnt mind being a pilot in real life either i just think Flight simulator is a good way for you to start aye:P

[Ednerd]

@ateamga yeah, don't listen to em. You may not be ready to fly but you are ready to take lessons. It's not that hard. I learned when I was 15. The main thing is you just don't want to get too laxed (spelling?) It's dangerous, so you take precautions and follow very anal checklists. As soon as you stop doing that...murphy's law will strike.

[sinkingrob11]

@Ednerd Ya I started when I was 12.

[abovetheclouds89]

What do the FAA regulations state in regards to height when performing an intentional stall? In Australia we must be recovered by 3000' AGL and it is not to be performed over a populated area, although that could also just be a requirement in the company's SOP's.

[bage881]

I think its an FAA regulation, not sure, but i don't think it is company related. Yesterday my instructor said:- Before performing these maneuvers you cud do a 90 Degree Left and Right Turn to make sure there is no traffic, make sure you aren't over a populated area, in case anything happens you won't crash into anyone's house etc. perform in an open area, like above the sea :) (I live in the Caribbean, lots of that)

[Muhammadz86]

sheetbug. using ailerons to pick up the wing will just increase the angle of attack on that wing there for it stalls more and infact that wing will drop faster than it would have without the aileron input.

[sheetbug]

ok I have a solo flight tomorrow. I shall try this manoeuvre (full spin recovery) and see if either the aileron or rudder works better. I'm guessing it will still be ailerons.

[sheetbug]

I've actually used the ailerons during the stall to recover the aircraft and it works better than rudder.  I don't understand why all these instructors scared about using it. When ever I practise stalls I always use ailerons and nothing happens. Instructors try to scare us I think saying we going to spin but thats all crap.

[westernbaseball4]

Right but then if you get into a spin you would use rudders to get out of it would you not? They just make it easier for themselves by not scaring away new pilots on their 3rd flight probably.

[q1o2]

sheetbug, they say not to use it because in a stall, very little wind is flowing over the wings, versus the rudder, which is right behind the air from the propellor.

[marsvolta87]

You are fucking retarded... you use the rudder because in a stall, the wings arent producing adequate lift and the ailerons wont have enough air moving over the control surface to have any effect....this just really shows how knowledgeable you are on the subject....

[trooper744]

sheet are u flying flight sim, if you will notice while in slow flight or even in a stall for that matter, ailerons become sloppy the a/c responds left, the aileron you will use to recover depending on which is down and up aileron will stall befor the other putting you into a spin situation, or maybe you will recover, but do u want to be 50% sure that it will work when your stalling on T/O or 100% sure the rudder will do the job. Follow SOPS, attention to detail saves lives..

[milehigher01]

ok fist question is this on FS. The reason that you dont use aileron to recover a wing drop in a stall is because the application of aileron increases drag. a wing drop is a sign that there is uneven lift forces on the wings (also can be a sign of uneven fuel use out of the wings) either way the down going wing has less lift than the other use of aileron = increase in drag = yaw in directon of drop= spin

[denhou1974]

It works better than rudder? That doesn't make sense. You use rudder to keep the plane from rolling into a spin. Power off stalls are practiced for a reason - they are most likely to occur during landing or engine out maneuvers. The wing will stall at the root 1st then move to the tips. Use what aileron u have left to keep wings level, use rudder to keep plane from rolling. The ailerons are gonna create drag in a stall. Why would they be 'better'? Read the POH for ANY plane.

[sheetbug]

Just a question, do you use the ailerons to control the stall?

[usmeagle91]

no, you use rudder

[gescoboza]

you sure you only want him as flight instructor?

[pbcmbeez22]

i want this guy as my flight instructor

[iareBIM]

I was scaring my instructor with my stalls back in the day; I used to bring the nose up almost vertically on purpose and he would always get angry.

[reallycba]

my instructor tells me to do that...

maybe he doesn't like me?

[ncn8ochaser]

lmao

[filian489]

Im just learning how to fly!

[ajetin]

nice but its not something hard

i do that every day

[ld8800]

i did that today :P

[JailNiggaUGay]

dirty power off stalls are fun

[braniffstyle]

Recovering from a power off stall is very easy. Its no big deal

[rayaviatorray]

The reason why Power-off and power-on stalls are simulated is to bring about awareness incase of an emergency during approach to land and takeoff respectively.

[JailNiggaUGay]

if you stall during landing your most likley crashing anyways and during takeoff you have to be retarded to stall

[bornfedslaughter]

whats the point of doing this? risking your life to test and make sure the plane goes on and off while flying?

Also that stall siren is fucking scary sounding.

[salemcripple]

It's to simulate what could happen during landing. Simulating an approach to landing. And that stall siren is suposto be scary, Alerting the pilot that something is wrong.

[JIMMYLINE]

this is to simulate a LANDING. Would you rather the student practice a REAL landing on a real runway before practicing or would you rather the student practice 5,000 feet in the sky where nobody can get hurt??

[multisyncxp]

@JIMMYLINE i don't agree with that. i'm a pilot, i may not have a large number of hours but i know how to stall; and also land correctly. The better way to 'simulate' a landing is slow flight. i actually have to go flying now but if you want a better explination let me know.

[JIMMYLINE]

@multisyncxp thanks for your input. I'm a pilot and I have a lot of hours and have been flying for about 13 years and have worked with over 12 CFIs. Slow flight simulates an APPROACH to landing, but the power off stall absolutely is to simulate a landing. 100% of all landings should entail a power off stall....slow flight is to simulate the approach. By contrast, a power ON stall is to simulate a stall at take off. Not sure what there is to disagree with here?

[multisyncxp]

@JIMMYLINE i'm not sure about your landings but generally (with few exceptions) i do not hear the stall horn while landing. Slow flight teaches control at slow aispeeds; such as the flare of a landing. Power off stalls would teach, stall recovery. i'm not saying stall training is un-importat; however slow flight better teaches the important aspect of a landing (well more important)

[JIMMYLINE]

pardon me for being humored. First you admit your a low-time pilot, and now your "schooling" me on what slow flight and power off stalls are. Okay.. When you "land," did the airplane "stop flying?" If the answer is "yes," then you can't call a landing "slow flight." I'm well aware of what slow flight is, stalls, etc. If you don't hear the stall horn on your landings, then your landing incorrectly (probably more flat than flare). Even in regular slow flight, you should hear the stall horn!

[multisyncxp]

@JIMMYLINE stall horn aside, if you 'stalled' the aircraft (i'm assuming nose wheel cuz its most common) on landing you would slam down the nose wheel. A flare is very close to stall speed as you know however not a stall. how could slow flight possibly show a approach as you stated earlier. I'm in a cessna, decent is 15K RPM, when i'm doing slow flight its around 21K if you did an approach to land at 21 you would miss the runway (unless you want to go crazy w/ flaps and slips)

[JIMMYLINE]

? Now what on earth are you talking about??? Every time you do a power on or off stall you need to raise the nose so the wings exceed the critical angle of attack! I stall the plane nearly 100% of the time I land and I've never hit the nosewheel. In regard to you "slow flight" comment, YOU are the one who said you use "slow flight to land," not I. The same argument you give me on approach I give back to you on landing. Do you mean to tell me you are turning 21k on LANDING? Let's not be silly.

[JIMMYLINE]

Are you sure you're pilot, or are you a student pilot? You sound inexperienced, and I just watched videos of you landing/taking off, plus two other ones you posted. You look like a kid! In the videos, you have an instructor sitting next to you (as seen by him manipulating the controls). I even heard him critiquing your landing (which was flat, and then drifted off center line). I've been flying probably since you were in diapers. I think you ought to be learning from us more, talking less.

[multisyncxp]

@JIMMYLINE ahaha you think he was manipulating the controls; he has NEVER touched the controls in flight (with the exception of the spin in which i was holding a camera) He was critiquing the yaw of the aircraft on landing. i was landing in gusty conditions, for some reason i land nose left. I am a student pilot however i am close to getting my PPL. and earlier sry i didn't have my coffee.

[JIMMYLINE]

exactly. You're a STUDENT pilot. Again, use your ears not your mouth. The information given to you by experienced pilots like myself who have 1000s (thousands) of hours and landings will save your life. I even noticed this in your critiques of @Crashboy1024 below. He's giving you life saving advice, and you are arguing with him? When you get some experience, I'd love to hear your opinion. In the mean time, use your ears to listen more to you instructor.

[UtahPilotChip]

@JIMMYLINE The purpose of any stall demonstration is to help the student recognize stall characteristics and learn proper recovery procedures... Because stalls generally occur during high angle of attack/low airspeed situations (take-off and landing) they are usually demonstrated in take-off or landing configuration. The best time to teach someone how to land is.. well.. during landing.

[JIMMYLINE]

@UtahPilotChip True. Which is another good point. Many real landings are performed in a power-off stall mode. What you posted is just another good point to what I was trying to say.

[toranamunter]

pilots are trained to confidently handle the aircraft during emergency situations, even a private pilot will do many dozens of stalls during his/her training.

The stall siren is scary sounding, intentionally, it tells the pilot he fucked up and is about to fall out of the sky unless he executes a stall recovery maneuver very quickly. These stall warnings have saved thousands of lives, but is never heard during normal operations.

[cobrachoppergirl]

cause its fun as hell. not as fun to stall on your tail, but you got all that altitude in the bank, might as well coast to the ground. gas is expensive.

[busterMC85]

lol!

[johnjeter]

what a moron

[floatplanepilot2]

Stalls are practiced to learn the symtoms associated with them to recover from an invertant stall before it happens.

They're also practiced to learn how to control the flare during a landing. A landing done right, the pilot stalls as the wheels touch down, with the stall horn blaring.

During a stall the airplane does not just stop flying. It is just unable to create a further increase in lift. The danger lies with an unware pilot, close to the ground.

[kajidono]

Only as often as I say Merry Christmases.

[nineninefour]

Lol.

[kajidono]

Thanks for posting these, very helpful. The term is RPM though, revolutions per minute. Saying RPM's is redundant.

[adamP90X]

what about runs batted in? Is it RBI or RBIs?

[kajidono]

Whichever baseball fan is more inebriated is correct.

[IMCOnAir]

would it be possible to fly such a air hopper with stopping the engine ??

[EricBlues]

Yes. Just like a glider. In fact pilots are trained to learn the proper configurations for optimal distance in case of an engine failure so they can land safely somewhere (landing strip or a field)

[kibareef]

first
