Stalling With the Nose Pointed Down

Рет қаралды 16,070

Күн бұрын

Most pilots associate stalling an airplane with pointing the nose above the horizon. However, it's entirely possible to stall an airplane with the nose pointed below the horizon, such as during a turn from base to final approach. In this instance, a pilot might increase the angle of attack without any obvious "visual" indication that he's approaching a stall. Watch the video to see how this can happen. This video is an excerpt from my upcoming new eCourse titled "How to Fly an Airplane," due out this summer (2024). Please visit my website to learn more: www.rodmachado.com.

Great video Rod. My instructor has always drummed into me, the stick or yoke position is the first give-away a stall is imminent. AOA is directly related to stick/yoke position. For example, if the stick is central or forward during the turn, the aircraft is not close to a stall.

As a 22 year CFI I have always stressed... "If a turn goes bad... LOWER THE NOSE!" I have also stressed that if a turn "starts out bad" that is what "go-arounds" were invented for... and that THERE IS NO SHAME in a go-around. Excellent illustrations and explanation Rod. Thank you.

Thank you, Sky. I like that idea: IF A TURN GOES BAD, LOWER THE NOSE. That's a simple and easy-to-remember phrase. So nice! And thank you for the comment, too. Best, Rod

Rod, I am so happy seeing new videos from you. Althow we had never met. I am from Czech Republic. You tought me all the basics for flying. It was from you beeing part of Microsoft Flight Simulator 2004. Your great commentaries, great writing, videos and pictures. And the most of it. Was the fun and humor you had put there. (for example while sitting in virtual cocpit of 737 and hearing your first words "you will do good but first you have to remove your hands from your eyes, yes, thats better...). I was never so eager to see and do another lesson there with you. I became pilot some years later, or worked on air traffic controll and instructor. My all basic knowlege goes to you my greatest mentor and teacher ❤❤❤

Thank You, I was never specifically illustrated and thought this. After ppl I got into that mess twice. One was while trying to take a photo and to stay where I was and circling got tighter and tighter. After I clicked the picture and brought my attention back to flying, I realized that I very nearly clicked my life. Second time was similar but no photos, just turning tighter and tighter to to keep my rented c-150 wing tip over a friends house. All the time loosing altitude. Both times scared me . That was in the 1980’s. Now age 63 and not flying watching your video put my stomach in my throat. I just wanted to give some real examples of how all the relations of aerodynamics can combine on a pilot without having learned or practiced this situation. Thank You! Dan from New Hampshire

Greetings Daniel: Years ago I watched a video of am Alaskan pilot in a Cessna 206 with several passengers on board. The video was shot by a passenger from the rear seat. The pilot was at 500 feet AGL (I suspect), and was circling around a bear on the ground. Apparently unaware of the bank angle and decrease in speed, he stalled the airplane and everyone on board perished in the resulting spin. I doubt that he was aware of his close proximity to the stall, perhaps for the same reason you experienced. It certainly caught him by surprise. Such a shame. Best, Rod

Years ago I started the difficult road to recurrency of my private pilot license. I tried the Gleim books. Although they were factually accurate they were as dry as dust. I started again with Rod's Private Pilot Handbook and along with his sense of humor he has such an accessible way of explaining both basic and difficult concepts. I especially remember how excellent his chapter on theoretical weather was. As an example his macroscopic explanation of weather was so simply explained in just 2 statements: (Paraphrasing from memory) 1) The sun heats the earth unevenly 2) Weather is the planet's way of distributing the heat And the rest of his teaching follows in the same way. Thanks Rod.

Airspeed is everything. This is where the concept of DMMS, Defined Minimum Maneuvering Speed, comes into play along with minimal, (not over 30°), banking in your turns in the pattern. Avoid this scenario in the first place. Great video to show what can happen if you get into this predicament.

Rod, I've been reading your columns and books for over 20 years, and today is the first time I've ever heard your voice. I guess I don't spend enough time on the internet. Watching this video reminds us of the usually poor outcome of manoeuvering flight at low altitude. I wonder if this is the same situation that took down the McSpadden crew. Throwing in that last shot of opposite rudder has killed a lot of pilots.

Thanks you Rod for the clear description with graphics. I never thought about this below the horizon stall before. Very informative. Sometimes, when I overshoot turning from base to final and realizing I am too high, I tend to lower the nose during the turn. I will keep this instruction in mind next time.

@Flight-Instructor 6 ай бұрын

Greetings Satya: Yes, when turning from base to final and steepening the turn, it's always better to release a little back pressure to prevent the stall speed from increasing. The problem is that some pilots will pull aft on the yoke to tighten the turn, which increases the angle of attack (which isn't immediately apparent because the nose raises at a diagonal as stated in the video). The load on their butts also increases which is a sure sign that their stall speed is increasing. No bueno when close to the ground. The rule is: Butt pressure increasing while approaching a stall; release the load on the yoke. Best, Rod

Somehow, I knew that since the plane was trimmed to 1.3x the stall speed that I shouldn't pull back on the yoke because that would put me closer to the stall speed. So, I only used the yoke for the ailerons and let the trim take care of the elevator. If I pulled or pushed on the yoke, it was only to get the plane back to the correct airspeed.

Everything is logical in this video and very well produced. However I must say that I didn't learn anything new even though I have nothing to do with piloting. A similar effect also occurs on motorcycles in sharp turns that's why you engage a little bit of throttle to maintain speed and turn radius. It feels like driving uphill, but the rear wheel gets actually less pressure and might lose traction earlier than expected. All my flying knowledge comes from war thunder PC game and aircrash documentarys. Greetings from Germany!(englisch is not my first language)

discussion: add up-elevator to a wing that is not level, and you get (more) Yaw moment; aka an aileron-initiated turn. in the situation described, in order to use up-elevator safely the wing must be leveled, first.

Basically, if the plane's nose wants to go down, let the nose do it and you're safe. Make only SLOW engine power adjustments to get the nose of the aircraft straight

I flew my Citabria for years without concern for angle of bank as much as for G load factor. For example, you can have zero airspeed and a 90 degree bank (zero G as you pivot around a vertical "stall turn") without the wing being stalled. If you have 1G or less load, your stall speeds will not increase over normal.

I use 1.5Vso as a minimum while maneuvering close to the ground - easy math. This provide 2+g load capability. I randomly ask pilots what speed they need in their airplane to sustain 2Gs. Thus far no one has been able to give me an answer off the top of their head. (Vso *1.41)

I was taught pitch controls the airspeed and power controls the altitude , the importance of coordinated flight and shallow turns in the traffic pattern. I don't do any "real world" flying anymore, but I don't know if this is what kept me out of trouble, or just pure luck. I am just a flight sim "pilot" now.

@feathermerchant 6 ай бұрын

When airspeed is too slow, aircraft have a feature called a 'stall' that automatically starts the recovery process. If the pilot(s) ignore that, then an alert feature called a 'spin' is employed to get their attention. If that fails, the aircraft automatically begins an emergency descent and 'lands' ;-)

Thank you for the comment. I'm not sure it matters all that much when backtracking since you want to spend as little time doing it as possible. In other words, backtrack fast and exit the runway as quickly as is reasonable. Best, Rod

Exceeding the critical angle of attack is the issue here. You are correct. Rod

@thomashesselgrave6898 6 ай бұрын

And this is exactly why you don't want to turn back to the runway when your engine quits after takeoff.

@davefoord1259 6 ай бұрын

Rob can you explain why this occurs. If you apply right rudder, the left wing aoa increases due to the right yaw, relative airflow from the left and the dihedral. But if youre near critical aoa, right rudder will result in the right wing stalling and a right incipient spin may follow. Why doesnt the left wing stall due to aoa above critical?

@AC-jk8wq 6 ай бұрын

While waiting for Rod to come by…. Private Pilot thoughts…. Sort of adding to the discussion. Not trying to answer the question…. At that critical moment… flying very close to a stall condition… The right yawing action…. Relatively speaking…. The Left wing tip is moved forwards into the wind, the right wing tip is moved backwards away from the wind… The local air speed over the wing tips is different than the airspeed measured at the pitot tube… The retreating wing stalls and drops first… How much yaw is related to how much rudder input is used, and how fast it gets applied… Wing tip speeds are magnified by how long the wings are from the plane’s center of gravity… See how fast a wing tip can move while taxiing in a circle… compare to the other wing. All it takes for one wing to stall vs. the other… is a few knots…. A very small amount. This is the driving force to maintain coordinated flight… keep the ball centered during the turns… PP thoughts only, not a CFI… Now, let’s wait for Rod to respond… the best real CFI! 😃

@Flight-Instructor 6 ай бұрын

Greetings Dave: Ultimately, the receding right wing's angle of attack increases faster than the left wing's angle of attack. Keep in mind that the left wing is also moving up slightly while it moves forward. This makes its increase in angle of attack slightly smaller than the wing that moves aft and downward (the right wing in your example). Nevertheless, this helps explain why both wings are technically stalled in a spin, with one more stalled more than the other. Best, Rod

@jumirjr.6597 6 ай бұрын

Excellent video. I have a question: would you feel the yoke bufetting in this condition? I mean, an stall with the nose lower than horizon. My impression is not once the tail would be out of the turbulent air

@Flight-Instructor 6 ай бұрын

Greetings Jumir: Yes, you probably would. If the airflow separation over the wing at the critical angle of attack is turbulent enough, you'll feel the pre-stall buffet. However, not all wings produce "noticeable" turbulence when reaching their critical angle of attack. In other words, some airplanes give you very little physical indication that the wing is about to stall. That said, if the wing produces buffeting when stalling, you'll feel this irrespective of the airplane's attitude as the critical angle of attack is reached. Best, Rod Machado
