Crazy Tunes Records in a stall the 737 nose will drop rather quickly, and type have to keep the wings level or the plane will roll rather violently. Combined with the nose at nearly 70 degrees, looking down at the Cascade Mountains, there was definitely pucker factor. That was the second time, different aircraft. The first time it was a stall, the Captain pulled the nose up too early and incurred a secondary stall. Much milder in the first aircraft but still a little edgy because the PF did not have a good grasp on 737 stall recovery. That was evident. And no bullsh&tting @C150flaps, or whatever your name is.

Stalls in light aircraft are inconsequential, easily flown into and out of. Stalls in jet aircraft, because if their high-speed low-drag wing designs, are much more difficult. It's good to know that at least someone is teaching stall recovery in jets.

@@feetgoaroundfullflapsC Flaps are not used to slow down, that is the job for speed brakes. This is one of the typical questions on an exam. You can descend the landing gear, provided that you are under max speed to deploy landing gear if you ever need to reduce airspeed such as in a rapid descent. Flaps have structural limitations and it's one of the reasons flaps are not used for slowing the plane down. In addition, there is a change in airflow and angle of attack incurred. So, with flaps comes a proper understanding of their use and how it affects the dynamics of the aircraft.

@@75supercourse you would think that, but no. Planes have crashed from pilot error due to stalls.

There's a lot going on when a swept wing transport category jet stalls, from independent stall warning systems, stall prevention systems, auto slats, engines that kick into high idle, etc, but if you take the actual aircraft into a forced "clean"stall it can easily get inverted with a little too much spoileron input. That's on a Boeing or McDonnell Douglas, and older jets behave differently than the newer series. There's also significant altitude loss involved, and that's why a takeoff/departure stall is so dangerous. Unfortunately those can happen down low, when you're heavy and there's not enough altitude to recover. Read about some of those stall accidents online, and you'll see how deadly that type can be. We only do full stalls in test flying between 15000-25000 feet. Usually start the maneuver closer to fl250. On some aircraft, we have to overcome or work around systems designed to prevent stalls entirely, because the mission is to confirm that the aircraft performs full stalls correctly. I'm glad that full stalls are being taught to line pilots nowadays. It will only make things safer for everyone.

This is because of the AF447 accident where the pilots held the aircraft in a stall all the way to the ocean from an altitude of 38,000 ft.

This is all good stuff. It is important for pilots to truly know how their equipment will react. Practicing stall to stick shaker and recovery isn't experiencing the full stall characteristics of the actual full stall of the aircraft. I wonder if the sim replicates every scenario a pilot can get into trouble in every stall situation and know how the aircraft reacts and recovers. Something most experienced pilot will know to avoid but great to really know what the aircraft will do if you venture into those situation.

Didn't go into a spin though so was the procedure ailerons neutral stick light pressure Forward, trim off, speed positive then pull back?

Wow, this is awesome.

Very interesting. I don’t recall any mention of the use of thrust as part of the recovery . In any event , the 737 having underslung engines, application of thrust generates a very large pitch up couple, which can induce the stall again. Oddly , in order to counter the rapid nose pitch up (due to thrust application ) the pilot may have to push forward on the control column, simultaneously applying nose down trim on the pickle switches, to limit the the nose pitch up. If this cannot be done quickly enough, the pilot must be prepared to reduce thrust somewhat to maintain control, ( and prevent a further stall ) an action which is totally opposite to what one would normally expect.

From what I understand, the heavies roll of the Boeing line and are flown out over the ocean where they can be yanked and banked to be fully checked out. I would assume stall testing is included in the regimen. I know the carrier (United, American, etc) testing of a four-seven that needs cold soak involves a most un-commercial climb out profile- they stand that thing on its tail and firewall the throttles to get it up to altitude as quick as possible. Many unorthodox maneuvers can take place during that testing, and I doubt stall testing would be much more stressful provided the airframe NE limitations were observed.

I wonder if this training was because of Air France 447... Does the simulator correctly generate the failure messages that they got? One of the issues was that when the AOA got out of range, it stopped annunciating the stall warnings, including the stick shaker. When the pilot pushed forward and got it back into the valid range, it immediately started giving alarms so he pulled back again. Of course, any pilot who knew basic aerodynamics would know it was in a stall because of the combination of low airspeed, full power, and decreasing altitude, but this pilot apparently wasn't trained very well.

So what would happen in a stall if you had a very strong tailwind (i.e. enough to pretty much cancel out your forward airspeed). Would that be recoverable (i'm assuming using full thrust)?

Tailwind doesn't matter unless it's gusts. You are in an air mass, you are moving with the air mass, relative to it. Also with a tailwind your ground speed is higher than your air speed.

Let's see that recovery on final approach.

Do they do a sim for when maintenance don't maintain the rear stabilizer and the plane goes inverted and crashes into the sea :/

Surprised that this isn't a standard part of commercial training seeing as for PPL you have to do stall and spin recovery training. It's unlikely that you'd ever need to use it, but still, you never know when some factors may adversely reduce Vs.

The sad part is, Denny is correct...many pilots of the big boys are trained to do procedures and run computers....shut that stuff down and many can't do the simple flight ops we do in private pilot training....I always said, "don't show me how to fly a plane, show me how to crash it "...If you know why they crash, you can learn to avoid that....I have had 3 engine failures on take off and an aircraft try to rip itself apart in flight so I am speaking from experience....

In a simulator at the time of a full stall and you kick full rudder into a spin, is it possible to recover from the spin? Is this ever practiced in a simulator?

It is not easy to create a spin in a big plane.

I remember the other video of an actual Boeing 717 stall test. Intentional stall.

It looked like they were in a dive forever regaining airspeed. Did any catch how much altitude was lost from initial stall to recovery?

Since they are up so high (and therefore the air is so much thinner), stall recovery (from a full stall) can actually require several thousand feet.

@briancox2721

Instructor said to delay recovery procedures until sink rate reached 9,000 ft/min. So start at 33,000 feet, decend/fall at an increasing rate until 9,000 ft/min is reached, then, and only then, initiate recovery. Seemed like half the time was waiting for to reach target sink rate before starting to recover. IRL, I imagine they are supposed to start recovery as soon as they detect the problem, and might not fall so far.

They make that look so easy. Me, Id be having to do a full underwear check after that. The advantage is the altitude for both stalls, still wouldn't change the scare the brown stuff out in the first place. Practice is a very good thing

Back when flight simulators first cane out, they didn't have stick shakers, they had a guy under the simulator actually holding the stick and shaking it

wow, that looked far more violent than I would have expected.

HardCoreGaming Corp was just autocorrection on the phone. So all times I flew with Airbus the planes had plenty of power, was new and flew very smoothly thru the bad weather (when there were some). All time I had to fly on a Boeing it was old, had to consume nearly the whole runway to get airborne and once in a rainstorm you could see that the plane was winding left an right. I knew Boeing had announced some new planes and might build them atm but I guess nobody here buy them because they already have some airbus and stick to them.

Ooo ! I wanna try !

Does the plane stall because I popped the clutch too fast?

Hope the passengers enjoyed it

With the downturn in travel this is how airlines can bring in more revenue. I’d pay for a back seat ride on an airliner doing that. Throw in an aileron roll too.

Can 737 recover from full stall break and 1 turn full spin ? Or crash ?

Way Back years ago 1982 I used to often train my flight training crews using the 727 simulator FULL stall recoveries. I think they learned a lot from that training, (relax back pressure, add FULL power) to many dummies just got confused (some of the worst pilots my airline had) and crashed instead. The excuse's I heard them say were pretty funny and really lame.

How much altitude did you lose between stalling and recovering from it?

@wiedehopf9068

6 жыл бұрын

That is one of the key training elements: A few years ago minimizing lost altitude was taught. If you take it to the extreme that can be a problem even low level. But at high altitudes once you have stalled it is impossible to recover without losing quite some altitude. You can see him pulling up very slowly but he does not have enough speed margin yet and the stick shaker activates again. So altitude loss is not the primary concern but a smooth pullout without overspeeding excessively.

I'm interested to know how the simulator hydraulics simulate the sensation of "falling" due to a full stall. It seems like that amount of motion would be beyond the motion range of the pumps. Does my question make sense? I hope it does.

Ummm swept wings stall at the tip first. They are totally different then flying a Cessna. You will NEVER stall a 737 on purpose. EVER unless you are a Boeing test pilot. I'm a commercial certificate holder, and hopefully on Wednesday, a flight instructor (CFIA)

It's not dangerous in a sense that skydiving isn't dangerous (but there is a small risk)....Like through extremely poor piloting, uncoordinated stalls, forcing secondary stalls etc. It takes THOUSANDS of feet to recover from a stall in a 737... It's only done on test flights, (like for certification or otherwise) Nobody goes out and flies at 10,000 dollars an hour to practice doing stalls in a giant swept wing jet.

FWIW 15,000 feet is a "low altitude" stall because shock waves and mach no. complications are not involved. At typical cruising altitudes these can cause more serious complications and loss of altitude and control. I.e. definitely going to spill some drinks!

1.) How does he make it stall? By switching off the engines? 2.) How does he solve the stall? By "hitting the gas", or by doing a nosedive so as to gain speed? 3.) How (if at all) would they simulate the plane flipping over, if the simulator itself obviously can't do this movement?

@nathanchetram287

taxiuniversum bringing the engines to their lowest thrust setting and pitching the plane up, it will begin to rapidly lose speed, a lot like a car going up a hill. The engines do not need to be turned off. 2) Pitching the nose down and setting full power on the engines are needed to get out of a stall. At high altitudes like on the first stall, the air is thin, so the plane is prone to secondary stalls (the plane stalls again when trying to pull out of the dive). Gentle inputs need to be made after the recovery, but the recovery itself needs to be fast and aggressive to prevent a loss of control. 3) The simulator can only go so far, so the pilots will only feel so much. You can't go upside down whilst in that kind of simulator. Being in a simulator will never be exactly like the real thing, although it is close.

Nathan Chetram Thank you. I wonder, though if at thin air, the plane might not TOTALLY get out if control. I mean, if the plane just tumbles down, wouldn't it be near impossible to make it face down, properly aligned and all? Then again, I guess if you can still give full thrust of the engines, the plane would still (or again) be maneuverable.

@nathanchetram287

7 жыл бұрын

taxiuniversum What you just described is called a deep stall. Basically, the aircraft is in such a configuration to allow for the wings to generate a "shadow" over the tail, preventing any air from flowing over the tail fins. The pitch control surfaces (elevators) are on the tail, and if no air flows over them they are rendered useless. That pretty much leaves the aircraft unrecoverable. Deep stalls pretty much happen on T-tail aircraft only, because of how the tail is designed. A T-tail aircraft (DC-9, MD-80 and CRJ-700) has the elevator and horizontal tail fin (horizontal stabilizer) mounted higher up on the tail, so it it easier to get it in that shadow I talked about. These planes have more advanced stall protection systems, like a stick pusher that will push the control column forward itself if approaching a deep stall, assuming the pilot has not done so yet.
