This 1945 U.S. Navy training film, Quit Stalling-Or Spin In! (MN-4353a), teaches pilots the dangers of stalling, or spinning, and how to avoid crashing. A stall is what happens when an aerofoil cannot make enough lift to keep the aircraft in level flight. The film features a Navy instructor who presents a series of case studies from the Navy’s office of Flight Safety Flight Statistics (00:52). The film begins with footage of a plane stalling and crashing into the ground (00:14); the remains of the pilot are recovered by the military. The Navy instructor reviews some of the key rules to avoid stalling: the steeper the bank or the sharper the pull-up-the higher the “G” (02:14); the higher the “G” and the heavier the load, the higher the stalling speed (03:10); and keep flying speed (03:31). Since more than half of all spin accidents occur during landing approaches, the Navy instructor reviews several cases involving landing approaches, including lacking speed during a turn (03:58) and slow gliding on aircraft carrier (05:20). Next, the film shows footage of a PV-1 as the narrator recounts a fatal spin accident involving the same plane, which killed the entire six-member crew. The instructor then discusses cases of crashes involving spin that occurred during takeoffs. This is followed by spin accidents that happened during simulated emergency training (07:32); in one case, an instructor and student on a b-stage flight in what appears to be a Navy N2S Stearman (08:09) entered a simulated spin but crashed due to insufficient altitude, with fault assigned to the instructor. The fourth key to avoiding crashes during spins is to never make steep turns at low altitudes (09:00). The instructor reviews graphs for necessary speeds based on the angle of bank to avoid spins for planes such as the N2S (09:24) and the F6F Hellcat (09:59). Another cause of crashes is pulling out of a spin too quickly, which results in falling into another spin, as is the case with an F6F cruising at 2000 feet (10:25). The Navy instructor then recaps the four other major classifications of spin accidents (12:00): those taking place due to emergency landings caused by engine failure; those traceable to unauthorized low flying or flathatting; those occurring at night or during reduced visibility; and those during dives or pull-outs. The training film concludes with footage of wrecks from several stalling accidents (13:04) and a reminder to be smart and avoid stalling or spinning.

They were the result of 52,651 aircraft accidents (6,039 involving fatalities) in 45 months. That was nearly 40 a day (although less than one accident in four resulted in total loss of the aircraft).

"..quit stalling and stay out of our files".....Sound advice. I am still a believer in unusual attitude training for pilots. I wouldn't be typing this now if I had not had that when I learned to fly in '90. I don't know if it ever "went through" but there was a push by some in GA to not teach spin recoveries on the idea that if the pilot never gets into a spin, they don't need to know how to recover from one.

@bikerjock2654 2 года назад

I’m a glider pilot, and it might be different in power flight, but I believe that the instruction to “not bank too steeply” is in itself not sufficient, especially on final turns. A pilot under high workload will apply extra rudder to bring the glider round in a shallow final turn, and if speed is too low, that will trigger a spin. I remember being taught shallow final turns, but it was eventually realised that eye witnesses usually saw the glider in a steep-turn attitude prior to hitting the ground because the glider had already started to spin from a shallow, slow turn with too much rudder. Having sufficient speed is the key message, rather than the angle of bank.

@flybobbie1449 2 года назад

GA aircraft tend to have high cord wing. Anything with a narrow chord tends to stall quickly and rapidly. I would image a narrow glider wing would do the same. Seen video of kit plane Pulsar pulling high turn after take off, flipped and crashed.

@riconui5227 2 года назад

Lots of problems start with trying to correct a heading with the rudder alone. Aircraft turn because of the angle of bank, not the rudder input. Gliders may be different from powered aircraft in response time, but the principle remains the same. If you are already banked pushing the a/c into a skid, (rudder into the direction of turn), you will be a higher risk for a low and slow stall/spin. This is the reason to develop regular habits for approaches or pattern work, and knowing how your particular a/c behaves at slow speeds. Train for how you will fly, and fly how you've been trained. I was a CFI for several years and that's my two bits.

@flybobbie1449 2 года назад

@@riconui5227 The rudder thing is a bit over blown. I get a few ppl's on check outs using too much rudder. Mainly because previous instructors over emphasized keeping in balance. Modern aircraft not much out of balance on turns. Unlike days of old like Sopwith Camel, would barely turn without rudder, but miss handled would bite.

@SoloRenegade 2 года назад

@@texaswunderkind My first time in combat, we were deployed, without knowing what the vehicles we'd be using looked like, and with no formalized nor successful tactics yet devised for the job we were tasked with doing. We had to figure it out on the fly and make it up as we went. Units we replaced were suffering up to 30% casualties. My company deployed 20 men short at only 100 men, and we lost only 1 in combat, and 3 others injured enough to be sent home. We figured it out and became top experts at what we did. But we had a rather unique unit and group of guys. It was a perfect storm of the right people in the right place with the right leadership to figure it out. The military signed huge contracts for the vehicles we used after that deployment, and many modifications we made to them are still being used, and many of the tactics we came up with became common practice across the military. Success in war is about adaptability, adapting on-the-fly, and knowing how you equipment works to find ways to use it to defeat the enemy's tactics and equipment (gotta seek to understand the enemy's equipment too). We did regular After Action Reviews after Every single mission while it was fresh in our minds, and devised changes to our own tactics daily to adapt to anything we saw or encountered, often times anticipating what the enemy would do next, or how they would change their tactics in response to us.

No, it doesn’t. American pilots would be best trained of the entire war. They went to combat knowing their aircraft in tactics very well. All pilots, regardless of experience level, have stalled and spun in. It is an easy coffin corner to get into when flying. As a pilot you have to be ever vigilant, and a moments lapse of focus can get you killed. The exact same mistakes described in this video still occur today. This is a great presentation of the stall spin problem and would be great for every CFI to show their students.

I find that most flying materials written back in WW2 approached the subject with the assumption that the pilot was coming into the lesson with zero college, zero flight time.

We're afraid to train like we should, for a variety of reasons. Looking at crashes due to engine failures- most fatalities are due to stall spin Loss of control, when the pilot fails to manage the glide and tries to stretch it to the selected spot, runs out of altitude, airspeed and options, all at once. Pilots of high performance complex aircraft do not practice power off approaches to any degree, and so when they need one, they're lousy at it. I also believe that not training pilots in actual spins early on is a bad Idea - if a pilots first spin is one entered by accident, it isn't going to his recovery any.

The word I’m missing here, is: “Angle of Attack”. Or rather: “Critical Angle of Attack”. Fly beyond that one, at any speed, and you’ll stall (and maybe spin). of course, unfortunately, we only have a airspeed indicator in normal aircraft, not an angle of attack indicator.

Hold on.. Weren't stalls associated with angle of attack and disturbed airflow over the wings?

@SoloRenegade 2 года назад

yes, but wing loading is part of that. Not sure what you mean by "distributed airflow over the wings though". Never heard anyone use those terms when discussing stalls.

@ululi1970 2 года назад

At a given air density, the lift provided by a wing is proportional to the speed squared, the proportionality constant being the lift coefficient. The latter is roughly proportional to the angle of attack, until a critical angle is reached (usually close to 15 degrees, unless slats and other devices are employed on the leading edge). Past that angle, the airflow over the wing separates, that is, instead of closely following the contour of the wing, it leaves the wing. In fact, in the separated region immediately over the wing the airflow is actually going towards the leading edge, as opposed to the away from it. This is what is referred to as disturbed airflow. When separation occurs, lift decreases rapidly while drag increases significantly. In most circumstances, stalls occur over one wing, while the other is still flying. The lift imbalance between the stalled and flying wing causes the plane to bank, while the drag differential introduces yaw: the result is a stall spin. Applying aileron to counteract the bank only makes things worse, because it demands more lift from a wing that is already stalled, which only increases the differential drag on that wing. Pilots are trained to recover from it, but it takes altitude. If the stall occurs during landing or taking off, the pilot may run out of air before... Airspeed figures in the equation because to provide so many G's without increasing airspeed, the pilot must increase the angle of attack (by pulling on the elevator). Once the angle of attack reaches the critical value, things get out of control pretty fast.

@B_Estes_Undegöetz 2 года назад

Stalls aren’t merely associated with angle of attack … stalls are in fact caused by exceeding the “critical” angle of attack, in all circumstances! And a spin is caused by the aircraft entering a stall with adverse yaw. That is how stalls and spins are taught today. But as we saw in the video here, stalls and spins were not taught this way back in the 1940s. Back in the 1940s it was felt that “angle of attack” was a concept that was too difficult and abstract a concept for student pilots to understand, so they taught about stalls using ideas like “Gs” and “stall speeds” even though this analysis of a stall is technically incorrect in many commonly occurring flight conditions. The idea of a “stall speed” is a particularly dangerous and misleading way of understanding how a wing stalls. Anyway, this older way of teaching stalls and spins to new civilian and private pilots persisted until into the 1970s until it was finally replaced by the correct analysis involving “angle of attack”. As for the “disturbed airflow over the wings” you mentioned, yes; when a wing stalls (when the critical angle of attack has been exceeded), the smooth flow of air over and under the wings becomes disturbed and turbulent, and as a result the lifting force, or just “the lift” being produced by the wings becomes insufficient to counterbalance the apparent weight of the aircraft. That’s why an aircraft in a stall begins to lose altitude; gravity has taken over. If however, when the wings of the aircraft stall the aircraft is in a condition with adverse yaw (yaw is the direction the aircraft’s nose is pointing compared to the direction the aircraft is actually moving through the air) then the pilot will find s/he’s in a much worse state then a stall. In the stall lift doesn’t completely go away; there just isn’t enough to counteract the weight of the aircraft, so the aircraft in a stall cannot maintain its altitude. With adverse yaw, however, one of the two stalled wings will be producing somewhat more lift than the other. In this case therefore the one wing with less lift would tend to drop much faster than the wing that’s producing a little more lift. This is what a spin is; the aircraft in a stall with adverse yaw will flip over, perhaps quickly and violently, toward the stalled wing that is producing less lift than the other. So there you go! You’re correct, and I’ve just outlined the basics of how stalls and spins are explained to beginners today. The video we just watched was how it was taught to beginners in wartime back in the 1940s, because it was felt angle of attack was something aerodynamicists, engineers, and aircraft designers needed to know, but it was too theoretical and complicated for the kind of men first learning to fly in the military in the 1940s.

@B_Estes_Undegöetz 2 года назад

@@SoloRenegade see my reply to the original reply above … “disturbed airflow over the wings” is one of the key ideas used to describe and explain the stalled condition in ground school and the flight lessons dedicated to “slow flight”, “stalls” and “spins” when you’re first learning to fly; as a civilian this would be when you’re working on you PPL (Private Pilot License). Wing loading is just the weight of the aircraft divided by the surface area of the wings (all measured in consistent and appropriate units … pounds per square inch, or kilograms per square meter, something like that. Wing loading isn’t a concept used in teaching or explaining the basics of stalls to new and low-time student pilots like the kind of young men this video was made for.

they don't always work. An older Cessna 150 from the 1960s has a stall horn, but it only works with the flaps at 40deg. At 0deg, 10deg, and 20deg of flaps, the plane will stall before the horn comes on. Since there is rarely a need to fly using 40deg flaps, the horn effectively never works. Stall horns have to be installed and adjusted for a specific configuration, and many aircraft thus face similar issues. But a competent pilot shouldn't be relying on the stall horn neither, and should learn/know their airspeed by pitch and power settings.

Flipping on your back into at inverted slip, will get your attention. Most General Aviation aircraft with recover if you release back pressure on the yoke.

At high altitudes man handling the controls can get you into a secondary stall.
