How NOT To Stall A Jet - Tech Tuesday

[@williegillie5712]

A stall can be a pretty serious situation. A few years ago I watched a KZbin video that had a lady taken in and out of a landing pattern and finally confused her enough her plane went below stall speed. The next thing shown was an outside surveillance camera catching the plane fall violently to the ground. Unfortunately the young Lady and her other two passengers were fatally injured and the plane was demolished. Thanks for the tech video Shaun much appreciated

[@timcaron9049]

I remember doing stalls (practice) on approach and take off and spins. I enjoyed learning those that I took an aerobatic course which was just to know what happens and how to recover. great video. Brings back many memories. Tim

[@timaz1066]

I had fun doing spin recoveries in an aerobat 150...always enter in in a nice climbing stall...fun stuff.

[@teddyballgame4823]

Thank you for taking the time out of your busy schedule for the Tech Tuesday video.

[@frankthomas855]

Thanks for the info. Most of you viewers know what goes into an aircraft stalling. I personally have never felt a stick shaker or seen a stick pusher in action. Thanks to you, i can now say i have. Although not in person. (Thank goodness)!

[@bashercrasherpops]

I love your channel, and please keep tech Tuesday is coming! I’m not a pilot, but have been a flight paramedic before… And also a rabid aviation enthusiast all my life. I love the routine crew operations that are the meat and potatoes of your channel, but I also have always been an amateur expert on crew operations and emergencies. All hail captains Haynes, Hamlin, Sullenberger, and Skiles… All hail! Don’t forget the crew that managed to crash land the triple seven with dual engine failure near Heathrow with no fatalities ., and many elders I haven’t mentioned… All aviation gods! Love the recent video of you and your copilot trying to navigate around and through a storm to a landing that was… Dicey. Anyway, keep them coming dude! Can’t get enough!

[@waukeshapilot6462]

Very well explained.

[@flexairz]

Not quite. The AoA indicates angle of attack, when its too large the wing stalls. He talks about low speeds, the aircraft can stall at any speed. When the stick shaker is active, its not telling your too slow, its telling that the AoA is too large, or almost. Stall has nothing to do with speed.

[@frankthomas855]

[@markmorgan5892]

flexairz so stalling has nothing to do with speed huh?! U said it right there in ur comment if ur AoA is to large then ur dropping in speed which would cause the stick shaker to go off!! That’s exactly what he was just saying and obviously u didn’t listen in the first part of the video, where he said that stalls can happen at any speed but he is just going to talk about to low of speed stall and back to ur AoA is to large then that is why the stick pusher would push the stick forward to get u out of the LOW SPEED stall because the AoA is to large, so in other words yes it does have to do with speed!!!!

When learning to fly I loved doing stalls and recovery. The one I really didn't like was the spiraling downwards ones. I knew it was coming as my instructor had me sit in the right hand seat. Took many an attempt to learn it. Never want to see or do it again.

[@gregjohnson8859]

Would like to see the stalls performed by the test pilot! Maybe you could make a video on that in the future. Thanks again for your videos!

[@cq7415]

Very interesting. It just pushes the yoke forward. On a piston airplane like a Cessna 172 you have to use rudder also because of the engine rotation pulling the plane to the left. Not that way on a jet engine. Thanks for this informative video.

[@KKG51]

Good Vid! I remember being scared stiff of doing power on stalls (departure stalls) by myself. The power off (Approach To Landing) weren't scary to me. Oh well

[@pjh9873]

You took the words out of my mouth. A short time later I found that the flight school I moved to didn't permit their students to do full power stalls while solo. That made me feel like a daredevil since I'd been doing them many times to become comfortable. Ever try a spin ? That's a blast. My private instructor bought a suped up 152 that was banner qualified and spin certified. We did one once and it was awesome learning to recover in real-life. Youth! ...... long ago.

What happens if the pushover starts when your at 200 ft. during landing? Great vids!

The pusher system deactivates for takeoff and landing. I think the height is 400 feet, but I have to check myself on that number.

[@kellandreader]

I've watched a lot of your vids, very interesting and informative. I live in Brunswick, GA and do a lot of biking on a bike path that's off the end of Runway 25 at Golden Isles. I've been here a little over two years now, and have seen a bunch of jets leave, flying over the path. Mighta been you in one of them, who knows? Keep the vids coming, and thanks.

[@CorporatePilotLife]

Nice! I've been to that airport a few times...

[@jimtorley70]

Thanks, Shawn!

[@alessio272]

A stall occurs when the aircraft exceeds the critical angle of attack. On this particular type a full stall is not recommended. Based on the swept wing profile of a jet the stall will begin at the wing tips therefore a loss of aileron authority will be inevitable. When these type of wings stall they will have roll control-ability issues. Frost on the wings will cause the aircraft to stall at a lower angle of attack and higher airspeed. Increased Bank angle also causes a stall at higher air speeds but at the same angle of attack. A question for you Shaun. Do you have DPE authorization to conduct type rating check rides?

[@CorporatePilotLife]

I don't have DPE authorization. I am a Check Airman in the Hawker and G-IV, but I can only conduct line checks in flight and knowledge check on the ground.

[@alessio272]

Corporate Pilot Life thanks. I lost my job with allegiant air back in May and I only have a A320 type rating and King Air 350. Its tough to find another job in the 121 world and 135s are wanting specific type ratings.

[@joeolivera1885]

So Shawn, How does the stick pushing forward word on landing? I think it would be a bit exciting to have that happen at 1000 fr or less when landing.

[@willyt7241]

Is there a minimum altitude agl for the stick pusher?

[@ss442es]

Very cool, thanks!

[@iowadrummer79]

I start this Saturday training in a 172. Not looking forward to stalls

[@CorporatePilotLife]

Congrats! The stalls can be intimidating at first, but they are very docile...especially in the 172

[@k1mgy]

Will the anti-stall system discriminate altitude above terrain? I imagine it would be a real bummer if, low and slow, the aircraft self-augered into terrain, where full throttle might have sufficed.

[@CorporatePilotLife]

Yep...I would have to verify the height above terrain, but I think it's 400 feet that it deactivates the pusher. It'll still give you the shaker to the ground though.

[@gtr1952]

Thanks Sean! That was interesting, had no idea what Vmc was in those. They don't require a stall for type rating? In the sim? Thanks!

[@CorporatePilotLife]

We do stall recovery in the sim, but we only take it to the shaker...not the pusher

[@stephenmucia442]

Sean, does the stall prevention systems work similar on a fly by wire stick?

[@RKHarm24]

What are the characteristics of a full deep stall in the Hawker?

[@CorporatePilotLife]

Pretty docile...not much different from smaller prop planes. As long as you keep it coordinated, it just shutters a bit and the nose falls straight down about 5 degrees nose low.

[@2time500winner]

[@dancharnas6374]

Yikes! Cool stuff, Shaun, thanks. Really enjoy these piloting discussion/presentations. Know you have a lot to do now, too. So, you know, thanks! Happy subscriber. Having been through stall training in small airplanes (like most of the folks who follow CPL), I enjoy your "Hey, idiot!" characterization for shaker or pusher activation in a corporate jet (or any high performance aircraft that has such stall-avoidance features installed for that matter). People who work in the seats you sit in are highly and recurrently trained and there is, I imagine, in our work, "No aerodynamic stalling, ever!" Ever. The incidence of the shaker unexpectedly coming alive in the cockpit would indicate that a huge problem exists and that a crew may be well behind the curve in managing the airplane's progress to a safe landing at its expected airport. No?

[@CorporatePilotLife]

That is definitely a true statement. We should never see a shaker in normal operations.

[@arthurpearson3407]

Shaun is it possible for a malfunction in the AOA circuit to activate the shaker in normal flight? How would you handle that?

[@CorporatePilotLife]

It is possible, but very unlikely. There are buttons next to the red lights that would disable the pusher, but the shaker would have to be disabled by pulling the circuit breaker.

[@JosiahMcDaniel]

Do these jets have keys? If so what do they look like.

[@CorporatePilotLife]

Not to start, but the doors and exterior access panels do have keys. Some are the circular shaped keys, and others have normal looking keys.

[@kevincollins8014]

Nice

[@MrSafetyForever]

As you performed the simulation and moved the yoke did the external control surfaces also move? Take Care

[@CorporatePilotLife]

yep...they're directly connected

[@MrSafetyForever]

@@CorporatePilotLife Thank you as I was not sure if a fly by wire system would recognize it was a stall simulation. Take Care

[@aileron48]

Another great vid., Shawn. Curious, what altitude do you practice stalls in the Hawker? Thanks!

[@superskullmaster]

You don’t. Unless you mean after a rebuild. Other than that they practice in the sim.

[@CorporatePilotLife]

When I did the demonstration with the test pilot, we used 16,000 feet. In the simulator, we practice them at low altitude right after takeoff or on approach to land.

[@xyzaero]

no aural stall warning?

[@johnpatrick1588]

Stalls depend only on angle of attack, not airspeed.

[@Flornmonk]

However, the slower an aircraft flies, the greater the angle of attack it needs to produce lift equal to the aircraft's weight. As the speed decreases further, at some point this angle will be equal to the critical (stall) angle of attack. This speed is called the "stall speed".

[@enterthematrix11]

Why dont you fly the gulfstream jet anymore?

[@CorporatePilotLife]

I still fly it from time to time, but demand for the large cabins is pretty low right now.

[@gsxr1kmatt]

How much faster than stall speed do you usually touch down? 1.1*Vs0? Out today with a fellow CFI and we were playing with precision full stall landings, and your talk had me wondering if the system deactivates when landing. - I assume it remains active, and also activates based on AoA rather than IAS, right?

[@CorporatePilotLife]

We typically touchdown around 1.2 Vso. As for the system, it keeps the shaker system active, but the pusher will deactivate, and yes they are based on AOA, not IAS.

[@maxmaxmaxmaxmaxmaxmaxmaxmax1]

I'd like to clarify your explanation of stalls. There are aerodynamic stalls and compressor stalls, but no engine stalls. An aerodynamic stall is when the angle of attack is too great and the center of pressure shifts way back. Basically, the wing stops creating enough lift and the nose drops. A compressor stall is when the turbine blades in the engine (essentially spinning wings) have an aerodynamic stall. The airflow at those turbines temporarily switch direction and you can get a buildup of gas followed by a uncontrolled detonation. It is quite dangerous to the health of the engine. A jet engine that fails and shuts down is called a flame-out.

[@nicks4597]

Cool :)

[@bigd-1-channel514]

I am not a fan of stick pushers, because if one was low and slow, and fighting an emergency situation, pushing the nose down would mean a crash. Now if there was some sort of low altitude detection logic thrown in, I could get behind it. I really am not a fan of computerized control. What can I say? Great Video, shame you were unable to get that Test flight into a video.
