J35 Bonanza Power-On Stall / Spin. Some important Lessons in this Review.
/ flywire
FlyWire is about exploring flight and the freedom this incredible experience brings us on a personal level. Flying has always captured the imagination and excitement of living life to its fullest. Hi, I'm Scott Perdue. In a former life I flew the F-4 and F-15E, more recently I retired from a major airline. I've written for several aviation magazines over the years, was a consultant for RAND, the USAF, Navy, NASA as well as few others, wrote a military thriller- 'Pale Moon Rising' (still on Kindle). But mostly I like flying, or teaching flying. Some of the most fun I had was with Tom Gresham on a TV show called 'Wings to Adventure". We flew lots of different airplanes all over the country. Now with FlyWire I want to showcase the fun in flying, share the joy and freedom of flight and explore the world with you. Make sure you subscribe if you want to go along for the ride!

For a while I owned a Bonanza of the same series. It was during a period when I was getting about 200 hours of flying time per year, so I was pretty well on top of my game. Not long into my ownership I decided to take her through a stall series at altitude, probably at 5000 feet or above. For power on stalls I recall a significant nose up attitude and probably above half throttle . I'm sure that my ball was centered. With little or no warning, the aircraft broke steeply to the left and entered a spin within a quarter turn. My reflexes served me well: keep the yoke in my belly, stop rotation with rudder, then nose down with elevator and recover smoothly. I did it several times, same result. My training had ALWAYS been to keep the stall going with elevator, to get the rotation stopped, and recover gently enough to avoid overspeed and not trigger a secondary stall. In all cases, I lost five hundred feet or so, maybe more. My first impression of all that was to recognize that Bonanzas happily gave up controlled flight. The break was surprisingly abrupt. I had done countless such maneuvers in a wide variety of Cessnas, Pipers, and other Beechcraft. This stall break, on the other hand, was frightening. I guess that's simply a characteristic of Bonanza wings. Live and learn. A year later I recreated nearly the same scenario with a passenger on board. I was flying formation with a Cessna 182 skydiving plane to my left. As the jumpers got out of the 182 and momentarily paused, the 182 slowed down. I did too and subconsciously added some rudder to keep a clear view of the jump plane. Then I was looking up at the wheat fields, and I won't relate what the passenger said. I had inadvertently cross-controlled the Bonanza very close to its stall speed and entered a spin before I could react at all. BUT, my reactions were perfectly reflexive and recovery was as described above. No harm, no foul. But a flat version of the power on stalls described above, at least insofar as the recovery. It ain't mushing around during slow flight practice where you get half a week of warning and virtually no break. After a lot of thought, I speculated that this characteristic gave hint to a death trap. Picture turning base with a strong crosswind that is now behind you. As you turn final at maybe 400 feet, the crosswind pushes you past the runway centerline. Reflexes are triggered, and in addition to banking back toward the centerline, you add just a little too much rudder, add some turbulence as that crosswind bounces over the terrain, and you are riding a death trap. Cross controlled stall at low altitude. A tiny mistake at the worst possible time, I would argue, in the worst possible airplane. Practice, practice, practice and know YOUR airplane.

I have a P35 Bonanza, V-tail. If-470 260 hp. Owned for 14 years and 1100hrs in type. About 2 years ago practicing stalls. Decided to try a power-on stall with an instructor. Had perhaps 60% power and planned to put nose down just when plane felt like it would stall. Let me tell you not to do that in a Bonanza. The usual buffet is very brief and plane snapped to the left and went nose down in a heart beat. Holy. Sh-t. So fast and probable got 1 or 2 rotations in less than 5 seconds. Pulled power, pushed yoke and neutral ailerons and did recover easily but I will never do this again in my Bonanza. I can definitely see a full power take off stall being deadly in a heart beat for a Bonanza.

This is why I have pilots recover from power on stalls at the first stall indication (usually stall warning horn, 5-7 knots above stall AoA under current conditions including G load), especially when the airplane is in the dirty go-around configuration. Another excellent discussion, Gunny.

You have a way of cutting rigtht to the meat with your safety vids, Scott. Power on stalls and spins can be pretty darned exciting in a 172. I imagine they get really sporty, really fast, in a Bonanza. I'm with you 100% with the pneumonics...power on stall/spin recovery is not the time or place to be reciting a poem. Thanks, Scott.

Excellent primer on stalls and spins Scott, best I've seen, heard or read and a nice add-on would be some in-flight demos. I also appreciated you mentioning your preference for flow over memonic cues, in a busy or high stress situation I believe flow is the better default and mnemonic cues more suited for lengthy procedural tasks. I was also adverse to power on stall practice and mentioned that to a friend (Carl Deitz) who who did some of the FAA recertification like testing on the twin Comanche. At the time I was flying an old 205hp B35 with the flatter V-tail and Carl insisted that I work out my apprehension about Power-on stalls in the Bonanza, and what Carl had me do was cross-controlled departure stall entry with full Aileron and input and raising the nose until a yaw moment was detected, and then lowering the nose until the yaw stopped, avoiding a stall break. Carl's training point was not to actually perform power on stall, but to emphasize awareness even slight Yaw divergence in departure climb, and make lowering the nose as the preeminent action to advert a spin . As Carl used to emphasize, spin avoidance is foremost a matter of awareness of when you are at risk and taking immediate actions to mitigate that risk, rather than out of unawareness, becoming an inadvertent test pilot. On subsequent flight reviews, I Practiced cross-controlled approach to a departure stall with Carl in a B55, Mooney and Twin Comanche, and from then on, my awareness of Yaw and preparedness to "lower the nose" became second nature. I had a Decathlon for a while, and did departure stall and spin practice with an old AF aerobatic instructor, and on my first attempts I did just what you said, over-pitched and ended up inverted. From then on I became an advocate that any serious pilot get some proper stall stall spin training and recovery training in a real aerobatic aircraft, from a real aerobatic instructor like you Scott, who understands it, and understands how to teach it. Also, a side note on V-tail Bonanza's, and especially the early models with the lower dihedral V-tails. A veteran Bonanza instructor once asked me if I had ever done a forward slip in my old B35 Bonanza, I admitted I as never found a reason to slip a Bonanza, with flaps extended and it was prohibited anyway. He indicated that in an off airport emergency landing I might have to, and I should be familiar with the characteristics. We practiced forward slips with flaps up and extended, and I found that with flaps and gear extended, with even a light forward slip, elevator authority was greatly reduced or eliminated. When I pressed a forward slip beyond the point elevator ineffectiveness, the old B-model abruptly lost all vertical stabilizer control and pitched down nearly vertically, with a simultaneous, rapid and extreme kick back on the yoke that almost knocked the yoke from my left hand. I tried this in a later 'P' model Bonanza with the taller v-stabs and found better control with flaps extended, and experienced no sudden departure from controlled flight in an extreme forward slip.. As such, I came away with a better understanding and respect for why not to slip Bonanzas.

Thank you for what you do Scott. This is invaluable information, and the visual explanation of everything that is occurring on the outside of the plane in a power on stall/spin makes it so much easier to visualise what the plane is doing from inside the cockpit, which really helps to enhance situational awareness and the steps required to recover the aircraft. I think being able to picture in your mind the outside of the plane from the inside of the plane will help to save lives.

I learned how to spin an airplane at 6 years. Really!, you say? Really. My father was a WWII vet and former B-29 pilot amongst 24's 25's and trained in PT-19's Vultees BT-13's. T-6's. On the back steps he set up a seat, stick and pedals for the lesson or lessons...been 66 years. Lesson: Stall, kick left or right and depart..."Pop the stick" full forward and mash the opposite rudder against the spin to stop the rotation...ease it out of the dive into a smooth recovery. Why the comment then? Well, the aft stick thing. I have a CMEI and been a pilot since I was 26. Now 73 and haven't flown for many years but I was taught, never, let me repeat, never, unless in an inverted spin is the stick pulled back."Lost in translation" issue is this statement.... "Pop the stick." What I presume, since Pop left on his final mission long ago, is that what he really meant was, neutalize it from full aft post haste, yet never had I heard of the aft stick technique. Not even in WWII training films. Thanks Scott!! It all makes sense and to quote a famous old Aviation writer, " I learned about flying from that."

I learned to fly in a C150 in 1969. Not much of a fan of power on stalls (especially in a turn), but it was "mandatory". On one hand I agree- how irrelevant are they to a cautious pilot. BUT- I did have a pretty wild (for me) experience in an AA1 Yankee during a checkout ride. Coming from Cessnas and Cherokees, this was like a sports car. At 5,000 AGL (and gross weight) the instructor told me to do a power off stall. When it buffeted and seemed to stall I added power and dropped the nose to below the horizon to gain airspeed. He thought that I lost too much altitude and said to try it again, but just add power and lower the nose to level. That worked great for about 2 seconds, then BANG- it spun to the left (my first and last "real" spin)-no C150 Cherokee ever bit me like this!. We both applied right rudder and I think I neutralized elevator(already looking at a lot of ground) but left on full power. Spin stopped, leveled out maybe 2,000 ft lower and we both decided I would be flying very conservatively after that! (2 more solo flights after that, partly to "get back on the horse". Lesson from this- a poor recovery from a power off stall in a less forgiving airplane can get you into a power on stall.

Fantastic stuff. In beginning aerobatics at our club the instructors will try and let you recover from upset/spins/unusual attitudes power on. Not simple and not always successful, power off you can fly out in fairly short order. The tufted wing is outstanding and settles the debate I think.

Thank you so much Scott for such an amazing video (as you always do). I have not done spin training yet. I was taught power to idle, neutral controls, let the spin stabilize before I apply the opposite rudder and slowly pull out of it and bring the power back. You took that and broke it down with such incredible detail and visual representation. Now I understand the aerodynamic principles and the “why” of what is done to recover. The full aft thing is new info and I greatly appreciate any and every minute life saving piece of information you provide.

@emergencylowmaneuvering7350
Most FAA inspectors cannot demonstrate a simple power off spin. Not even on an easy C172 from 7k agl. and wont promote that you learn them either. They can do Mostly Mild Maneuvering instead. Canada, Mexico, Latin America, and Europe, most inspectors know spins. What a shame is that.

@EricJanOud
@EricJanOud 2 года назад
Only other thing I can think of that happened is that the pilot in question was practicing slow flight; not so much power on stalls. It may well have inadvertantly developed into one, but practicing slow flight that has gone bad is i.m.h.o. a realistic option. especially because he was "less current" (and probably "less proficient" because of that), and he went out to do some airwork to re-acquaint himself with the airplane. If you take the region of reverse command a touch too far... Great analysis and aerodynamics explanation, Scott. Thanks for that! :)

What a wonderful presentation Scott. It's packed full of very valuable information! I wish I lived closer, because I would love to do some upset training with you. I'll be honest, I've never heard the full aft stick after you pull the power and neturalize/center the ailerons, but after watching the demonstration, it makes perfectly good sense. I assume every aircraft has it's own tendencies, so it may depend on the aircraft your flying? I've always been taught, pull the power, center stick, opposite rudder, then break the stall with just enough elevator.

@GZA036
@GZA036 Год назад
I had never thought of forward elevator as a pro-spin input. The Cessna 172M manual says to hold full aft elevator for the spin entry. But interestingly, if you follow the instructions, full aft elevator is held until just after the opposite rudder is applied. Technically, recovery still starts with IDLE NEUTRAL AFT. "The normal entry is made from a power-off stall. As the stall is approached, the elevator control should be smoothly pulled to the full aft position. Just prior to reaching the stall ''break", rudder control in the desired direction of the spin rotation should be applied so that full rudder deflection is reached almost simultaneously with reaching full aft elevator. A slightly greater rate of deceleration than for normal stall entries, application of ailerons in the direction of the desired spin, and the use of power at the entry will assure more consistent and positive entries to the spin. As the airplane begins to spin, reduce the power to idle and return the ailerons to neutral. Both elevator and rudder controls should be held full with the spin until the spin recovery is initiated. An inadvertent relaxation of either of these controls could result in the development of a nosedown spiral." .......... "Regardless of how many turns the spin is held or how it is entered the following recovery technique should be used: (1) VERIFY THAT THROTTLE IS IN IDLE POSITION AND AILERONS ARE NEUTRAL. (2) APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIRECTION OF ROTATION. (3) JUST AFTER THE RUDDER REACHES THE STOP, MOVE THE CONTROL WHEEL BRISKLY FORWARD FAR ENOUGH TO BREAK THE STALL. (4) HOLD THESE CONTROL INPUTS UNTIL ROTATION STOPS. (5) AS ROTATION STOPS, NEUTRALIZE RUDDER AND MAKE A SMOOTH RECOVERY FROM THE RESULTING DIVE."

I’m not usually fond of mnemonics, but I like PARE, mostly because it’s so well known and so important for extricating from a spin in almost any GA airplane. It’s the same steps as you describe, but much better known in the GA community. Power off, Ailerons neutral, Rudder opposite to stop the spin and then neutral when the rotation stops, Elevator forward to break the stall and then gradually back to level off. I suggest that the Bonanza pilot, whether he knew PARE or had any spin knowledge or training at all, undoubtedly panicked and froze when the airplane flipped into a spin. As anyone who has done any spins knows, that first time is pretty scary, even when it’s being demonstrated by a competent instructor. When I was instructing back in the 80s, I had a private pilot freeze at the controls of a 182 when a power-on stall broke into a spin. It was my fault-I’d taught him in his private training to “walk the rudders” (falling leaf) as a means of demonstrating how the rudder retains authority during a stall, even when the elevator and ailerons have lost their authority. We’d done that both power off and power on in a 172, and he had no trouble. After he obtained his private certificate, he wanted to check out in the 182. At altitude, we were doing the usual air work including stalls. I had him do a falling leaf, and he was impressed with the additional authority that the 182’s rudder had compared to the 172’s. I then said not to try doing that power on, because the additional power made it too difficult. I think I said “nobody can do it”, my student said “I bet I can”, and like a dummy, I said “OK, smart guy, try it”. Of course, the deck angle was extreme. As the airplane oscillated to the left, he pressed the right rudder, it oscillated to the right, he pressed the left rudder, and suddenly the airplane flipped over to the left and fell into a spin. Because I’d also taught him spin recovery, I expected him to react, but he didn’t. He froze, still pushing the left rudder and with the yoke still back all the way, with full power. I first tried to talk him out of the spin, but when I realized I couldn’t get any reaction from him, I pulled the throttle off, used all the strength I had to push the opposite rudder, and I had to hit his wrists with my arm to knock his hands off the yoke. I don’t know how many turns, but we lost over 3000 feet, from 11,000’ to below 8,000’ MSL. It was not until we were flying straight and level that he “woke up”-he didn’t remember any of the spinning. So that’s why my guess is that the Bonanza pilot either had no idea what to do, or he simply froze and left the controls however they were when the airplane entered the spin. That the throttle was still at full power supports my guess, since pulling the power is the first step in recovering from a spin.

Here's a place RC models teach you to do it wrong. The models have so much power, the prop can just pull the airplane out of the spin on neutral controls. Many models can pull up and out of the flat spin by using power. (impossible for full scale) While the models can teach you some good things, they can teach you bad habits.

@markmuir7338 2 года назад
So far as I understand, many GA aircraft will recover from most spins by holding neutral controls and leaving power where it was - you just wait it out. This applies to aircraft that were designed to have the wing tips stall long after the majority of the wing has stalled. Cessna sales guys like to tell you this on trial flights. It's not the best technique though! I think the reason that adding power brings RC planes out of the spin - even when the full-size aircraft it's based on won't - is the extra slipstream over the tail increasing the lift of the vertical stabilizer, which neutralizes the yaw. I'd like to hear any other theories though.
@fhuber7507
@fhuber7507 2 года назад
@@markmuir7338 Holding neutral means knowing where neutral is. The models have an advantage. Let go and the sticks spring center. The servos drive the controls to neutral. The servos and controls are sized to overcome ANY potential in flight forces and push the control to the ":commanded" position (even if the "command" is letting the stick self-center) The model "knows" where neutral is. As stated in the video, the aerodynamic forces, will try to move the rudder into the spin. It's not as easy to KNOW you have the rudder centered as it is to just push it on over opposed to the spin. But the real key to powering out of a spin with RC is the tremendous power : weight advantage. Piper Cub appx 0.3 : 1 power : Weight. C-152 appx 0.5 : 1 Average RC model 1.0 : 1 to more than 3.0 : 1. The model isn't depending on airspeed to drive enough air over the rudder to straighten it out. The prop is pushing enough air back to do it.
@FlyWirescottperdue
@FlyWirescottperdue 2 года назад
Actually, I think it is more likely due to polar moments of inertia. The center of the spin axis versus the CG and the location of the power thrust line.
@fhuber7507
@fhuber7507 2 года назад
@@FlyWirescottperdue we push CG forward compared to general aviation aircraft on trainers, but far aft of what is considered safe for general aviation when setting up extreme aerobatic models. It's hard to compare inertia moments of the wings because they vary considerably based on construction. We mostly see a difference in rotation rate being slightly slower with heavy sheeted and fiberglassed wings, but still immediate end to a spin with power on. Pusher designs almost always require power off for spin recovery when tail planes are not in the prop wash. EDF (electric ducted fans, simulating jets, but with tremendous motor torque) also need power off for spin recovery. These just spin faster with power as nothing is in the path of the high speed air exiting the thrust tube. And the thrust is applied behind both CG and center of drag. I have a pusher flying wing that when spinning inverted, apply full power and it spins so rapidly it climbs. Turn off the electric motor to get out of the spin. The power to weight seems to be the most important factor for powering a model out of a spin with a conventional designs. (prop in front, main wing with CG 5% to 46% MAC of main wing + tail planes significantly smaller than main wing) More power, pushing more air over flying surfaces breaks the stall and it straightens right out, accelerating in whatever direction the nose is pointed. (Including straight up.) Our model prop diameters tend to be smaller than scale when using "glow fuel" power, but can be at scale for gasoline and electric powered models. (Ground clearance generally prevents oversized) I like discussing similarities and differences of aircraft types and effects of changing scale.

@bearlemley
@bearlemley 2 года назад
Something interesting I learned years ago is that what is the number of possible different spins there are on an aircraft. Add complexity and the number multiplies to well over a hundred thousand different spins. Think about all the possibilities of changing the longitudinal, lateral and vertical centers of gravity a tenth or half an inch at a time. And in fuel moments for different fuel loads, power settings, rpm settings and flap and landing gear positions. Does a manufacture who must demonstrate recovery in a single engine, explore all of these possibilities? The answer is no they don’t. For one the costs and time required to investigate all the possible spins is prohibitive. The field certification branches know this and will hear arguments from the manufacturer on why 6, 8 or 10 configurations are thought to be the worst and will approve the study to be on that groups. The flight test program might show early on that the prototype to be recovering easily without deploying the spin chute and the amount of required spins can be cut down. By the time type cert comes around, very few spins from the vast possibilities of different configurations have been deeply investigated. It can go the other way where a spin test program can go poorly and drag on for ever. My point is that no one has don’t all the spins in an aircraft. When you spin you very well might be the first. Hopefully your aircraft and the humans on board will be equipped like a well run flight test program with easy egress and parachutes. Even then you will loose now and the. Let remember Art Scholl where the weight and moment of a video camera on a cable added to the list of configurations possible in a pits and one that no one had ever explored before.

Depending on aircraft model, configuration and situation stomping the rudder to its stop, if done early, may create a wingdrop on the 'stomped side'. It can be the lesser of two evils, but the action might also (possibly) be futher refined/optimised by less 'hurried' response.

This one is really good! Another point to remember, when your anti-spin input is working, i.e. the nose dropping the yaw rate might actually increase momentarily as the masses realign around the spin axis like an ice skater pulling the arms in to increase rate. (actually the axis is relocating but with the same effect) I only really flew gliders, so at least there was no power setting to worry about :)

Scott, as always, I learn so much from your videos. I fly a J35, and I am a RU-vid contributor. I'm not sure how your extensive knowledge helps me understand this accident because most of the information and demonstration relate to conventional tailed aircraft. As you said you are not sure how any of this relates to the V-Tail. Clearly, the down input won't affect airflow on a vertical surface because there isn't one. My first response in my airplane, would be to pull power and neutralize control input. After that I would fly the airplane based on how it responds. Your thoughts?

Great video thank you for doing it. I was thinking about a spin accident I witnessed years ago in a Ryan pt-22. I was just learning to fly in a Aeronca and had completed spin training. A older friend at Van Sant had just bought a Ryan pt-22 by older he was 24 I was 14. My Dad was teaching me to fly the Aeronca and he insisted on spin training. Ok back to the Ryan. My Dad’s friend had taught in the Army Air corp in the T-6. Mac was his name. He was also a captain with TWA and owned and flew a Stearman he had just upper to 300hp from 225. Anyway Mac was going to check out Kent in the Ryan. We were sitting on the fence at the Pennsylvania country airport and watched the Ryan take off with Kent in the back seat and Mac in the front. We watched them climb to altitude and do various maneuvers. They did one spin entry and in 3 rotations recovered and climbed up to altitude again. Then they purposefully entered another spin and it kept spinning 5, 6 , 15 rotations and then disappeared behind the trees. Mac & Kent were both killed. We found out later the rudder cable between the front seat and back seat had snapped. Making it such that Mac the instructor had no rudder control. Kent had frozen on the controls with his feet pressed hard against the rudders. Kent had frozen in flight on a number of flights in the Stearman. The both had parachute but Mac turned the fuel off before impact and never bailed. Remember that Ryan was at 45 degrees spinning. Mac had no place to put his feet to push out of the cockpit. The reason I bring this whole traumatic story up was Mac had told me to recover the Ryan pt-22 you need to first stop the spin. Neutral controls and rudder to stop the spin. Then push the nose down getting airflow over the wing. That unless you stopped the rotation first in the Ryan it would not recover from the spin.
