The pilot would have just a few moments during the first half rotation to make a rough calculation of where they will come down. He knows how fast he is going and his vertical speed. The pilot successfully crashed the aircraft away from infrastructure and people on the ground in my opinion
As a helo pilot, these situations and responses are a great visual...thank you and yes. enter auto IMMEDIATELY is key. In particular with no forward air speed, and of course increasing collective to flair before setting down.
When this happens you should have 3 options, try to make it w/o injuries, try to make it living critical for life, or just pin it into the ground as quickly as possible to be knocked out enough to have no pain?
Great channel,I admire your work!
I wonder if a bird hit the rotor, or the pilot had a heart attack.
Awful shame. RIP
According to a preliminary report it was a mechanical failure that caused the loss of a tail rotor control. Basically it was still turning, but it was useless, because its pitch control was lost. Whether this happened due to design flaw, manufactoring, maintainance or something else, is yet to be determined.
Heli Channel
Awful.
Nothing he could do if he couldn't control the rudder.
Maybe turn off the engine and try an emergency landing, but he didn't have much altitude
Awful, awful, awful
@@CraigMansfield He would need forward speed for that and it's called auto-rotation and yes his altitude didn't weigh in any favours.
Yes......poor birdie.
i wonder if a helicopter parachute would have helped in this situation or Vertical thrust injectors just before impact
Its amazing planes and helicopters can stay in the air ..bit of a gamble traveling on them.
francis begbie sane with a car I guess
Planes not really a gamble heilcopters yes very much a gamble
@@akmedia8206 Agree! The club owner was a billionaire. Why he entrusted his life to a small dangerous helicopter baffles me! I live near LCFC training ground and that thing used to fly low over my house every Saturday. Never liked helicopters, don't trust them!
RIP Vichai
hi, please can i ask how you got this leicester scenery pack on xplane 11
I've put it together myself. Stadium is converted from a 3Dwarehouse model.
Oh cool is there any way you could share this file to me ?
Write down your e-mail address.
Thank you for the very informative video.
IMO you tried everything except that which is called for in every RFM I have ever read...namely, dumping collective pitch and gaining airspeed so as to get some degree of anti-rotation control from the vertical fin(s). For the helicopter I fly, that speed is 70 knots. I'm at a loss why you didn't attempt this instead of the unheard of (to me) tactic of applying counter-rotational cyclic. Are you helicopter rated or just a computer/simulation hobbyist? Please reply if you are interested in repeating your experiments and using known and recommended techniques that might be successful.
Thank you for your reply. It is clearly stated that I am not certified at anything, meaning: not a real pilot. However I have put a lot of effort and time, during the recent years, to increase my knowledge regarding these magnificient machines. This quest is ongoing, therefore every constructive bit of information is welcomed and appreciated on this channel. Your comment made me do some additional testing in a simulator with following results.
The height from where I was able to transition to autorotation with a significant forward speed (50-60kts) was 350-400ft AGL and above, provided the action was started immediately during the onset of yaw motion, meaning I anticipated failure, while IRL they would be needing extra seconds for analysis and end up spinning substantially even before taking any action.
To conclude. Failure height in this video was set to 250-300ft AGL, which is below the height where It was (in a virtual enviroment) still possible to trade height for some airspeed. However I have later found out that the unfortunate G-VSKP was actually higher, at the 430ft RALT, and that might open at least theoretical possibilities, while the grim outcome is already known.
No matter how comfy or how much money a helicopter costs .It's still a risky investment .If it crash you die .See what happened to kobe Bryant ? Never travel in a helicopter
Kobe’s crash was pilot error. He flew into IMC without TWAS in a hilly area. He was VFR flying into IFR conditions which is illegal.
So it was found in investigation to be tail rotor linkage failure. Surely by 2018/19 helicopter designers could have worked out redundancy for tail rotor failures- engine exhaust bleed air directed out side of tail or ballistic parachutes?! How can a company sell a luxury item to a billionaire knowing that if it has this failure the occupants are pretty much dead...and as much as witnesses and experts liked to think that the pilot steered away from more casualties, in reality he would have much preferred to stick that craft into the grass pitch he left from if he had any control of the situation...it wouldn’t have hit the deck at more than 40/50 mph(we can see this in the real footage) and fuel tanks may not have ruptured hitting the grass. Drop a glass bottle onto grass it’ll prob be fine, drop onto pavement it’ll likely smash.
RIP all aboard.
Dear Sail Cryer,
I think that before writing statements about these tragic events, everyone should be adequately informed and must be familiar with the argument.
First of all, a glass bottle that hits the ground at a speed of 1000 FPM will get the same impact acceleration (which is the element that matters) on both grass and asphalt surfaces.
And helicopters equipped with wheel type landing gear are not made to execute rolled landings on the grass, especially in autorotation. Neither me nor you were on board, so we don't know what the pilot did "in reality" .
About your other questions, I can tell you that ballistic parachutes (mandatory for ultralight A/C) are unable to work properly with these weights and an uncontrolled yaw like that and the low altitude would not have allowed the opening.
Engine exhaust bleed Air can't be used to counteract the torque of high performance rotors.
And all the helicopters in the world could have a tail rotor failure (regardless of the manufacturer), otherwise there would be no special section on all QRHs. Customers can buy helicopters with dual main rotors to avoid this problem, but the performance would be different and the costs higher. So the only ways to solve these problems are good maintenance and well-trained pilots.
Best regards
I’ve been told by someone more informed and articulate than myself.
But;
Where there’s a will there must be a way.
FYi I’m not an at any cost life preservationist...we can never expect ourselves to find perfection but the world seems to crave it- An extremely safe craft had a freaky low level malfunction and all perished, accidents happen. I just can’t believe the life preservation engineers haven’t worked out a way to have redundancy for tail rotor situations beyond auto rotation. I don’t think it should be in the impossible basket.
I’ve seen a light aircraft deploy a chute over my farm....an impressive invention that I thought chopper and hot air balloon engineers would further develop for their operating envelopes.
How about a rocket in the tail that counteracts the rotor tourque and burns for say up to 60 seconds?
@@Whatevershappeninginmyhead the rocket is a great idea, I don't understand why the engineers didn't realize it before. You should patent and present the project to the main companies 👍
@@Whatevershappeninginmyhead I think putting explosive rockets on any aircraft is dangerous, end up causing more accidents trying to solve one. Only military would do that for performance enhancement.
The chute above the aircraft idea is good, unfortunately with about 250 ft like this accident there's little hope for that to work as well.
The tail rotor redundancy idea is not economically viable. Every kg of redundancy is less payload and more fuel consumption, they just don't sell. It's like asking Airbus to build aircraft with an extra pair of tail vertical fin or elevators in case the first set fails. There are certain elements essential for flight, and doesn't have redundancy as it non operation basically violates it's airworthiness meaning they should never have taken off in the first place if found to be not in good shape at pre flight inspection. Where failures occurs only after setting in flight with good pre flight inspection, that's just unlucky.
I agree proper, regular and prudent inspections are critical in preventing accidents, however I have seen pre flights checks where pilots would spot some potential issues, but would consider the need for fixing or grounding in future and not immediate, such decisions are routinely made, aircraft with hundreds of moving parts doesn't stay in pristine conditions even after first flight, you don't just replace every component after a few hours using them. There's also the pressure on the operator to keep aircraft flying and cash coming in, potentially overriding pilots decision of fixing the plane or grounding it. Or fix with minimum disruption to trade/operation of craft. Yes it's borderline unethical but that's where conflict occurs between business and risk.
I saw many crashes of AH-64 Apache, the crew was survived, the ship was not burned the crash speed is faster than this AW-169, why AW-169 Fire very fast?
Different design objectives. AH-64/UH-60 were designed to be shot at and eventually shot-down. Costs were not a limiting factor. However every design is a compromise and in a civilian enviroment performance vs. operational costs is essential. No one really buys these things to crash in. I have briefly checked Leonardo's site and military version AW169M does indeed feature self sealing crash resistant fuel tanks, but I haven't found the same to be true about the standard version.
T_SixtyFive X_Wing They are bulletproof and have airbags too
I think the fly by wire can not control tail rotor to counter torqe of main rotor. And the computer with autogyro that got signal body yaw or spin must command full pitch to tail rotor but linkage is broken then the pitch and cyclic of main rotor may be mis calculate and that make manual correction is hard to manage cause of the computer that govern fly by wire not program the mode in this situation of failure. If software is good enough, may be this special good program could save everyone'lifes.
Still no advancement in helicopter safety technology. :'D How long have helicopters been around, though?
I'm neither aircrew or an
aircraft engineer.
(I have worked in ATC)
Would cutting off the main rotor have stopped the aircraft's fuselage rotating around the blades?
I once worked alongside a
helicopter pilot, and was told it is possible to glide a helicopter down to the ground, from a height similar to this.
May They Rest In Peace. 💐
no the blades need to spin,,, or you drop like a stone,, usually these incidents are non survivable,, you drop the nose and hope the airspeed slows the rotation i guess and try and flair before impact but in their situation just avoiding killing anyone else is about all you could do
i been there
first
There was no sound at all or was very very low level as u couldn't hear .
I'm sure if the Notar system would be the best/safest option manufacturers would use the system!!
Back in 1997, a medical helicopter here in Denver crashed just after takeoff when it struck overhead powerlines. I was recently in the hospital for surgery and I happened to talk with a doctor who was scheduled to be on that flight, but he cancelled at the last minute. He said if the helicopter had been just a few inches higher, it would have cleared the lines. Those powerlines weren't thin little wires. They were thick metal cables.
When the helicopter tangled with the powerlines, the rotor blades just STOPPED!! The rotational momentum of the rotors was immediately transferred to the body of the helicopter causing it to rotate (i.e. snap) in the opposite direction.
The rotation was so rapid and violent that those on board were killed when their bodies out-rotated their hearts in their chest cavities, severing cardiac arteries and nerve connections.
That's insane
What a way to go that sounds horrific
Stonage technology
The video is quite good. Very well explained the situation. Regarding the possible actions to take I do not think that autorrotation and cushioning is the best option, because with autorrotation the helicopter initiates a descent so fast that an adecuate cushioning at the correct moment will be almost impossible to achieve. It's better to down collective a little to initiate a controlled descent trying to keep the helicopter leveled. Yes, you will spin a lot, but this won't kill you. What can kill all the people on board is a high variometer. Almost every pilot can do it, while an autorrotation with a cushioning good enough to survive is highly unprobable even in well trained pilots.
You are making a valid point there. Cushioning was somewhat successful only after several attempts and sucess rate was pretty low. However, at least in simulation, this was the only option where I felt I had some control over the inevitable. Every extra second staying in the air has only worsened the situation.
@@helichannel8475 Hi guys! Yes i wonder whether the onboard computer could land it. Obviously a forced crashland. But maybe it could have an auto emergency decent and cushioning. I suspect that pilot disorientation will be the main factor in getting it down. Maybe the computer could also have some small cyclic control while spinning?
I'm no expert, but surely an air bag system that deploys moments before impact would cushion the aircraft enough to avoid catastrophic Outcome something has to be better than nothing when the only thing that is certain is a crash landing.. Surely there is things that can be done to insure safety of private owners and public alike.. RIP to all those on board and hopefully this helps push for innovation in aircraft safety
@@williamcollects393 yep, you are no expert, lol.
@@palacio802 hey I will let the experts retort with my innovative idea 😂
Pilot shouldn't have let his wife have a go
Great simulation¡¡¡
would these guys have survived the initial impact?
Final report will probably replace guesses with facts. AW169 does come with a "blackbox" flight recorder filled with plenty of data.
I wonder what would the result would have been if he'd flown out of the other side of the stadium, and gone down in the weir? - It's very wide and only a few feet deep.
ข่าวไทย ก้ออกครับ
Very interesting, thanks !
damn im never sitting my ass in a helicopter after seeing this. So basically you are 100% dead if the engine somehow just stops working.
King Power biggest mafia crooks in ThILAND
90sDawg this is how kobe died the helicopter spun out of control
Got Game no man they crashed in to a hill because the helicopter flew too low
True see what happened to kobe too?
@@Sequel7 no, Kobe died because his pilot flew into IFR conditions without TWAS, and flew into a hill.
there should be a way to dump fuel or make it so it doesn't cause an explosion in these situations if it wasn't for the fire and explosion there could well have been survivors
Im pretty sure if you dump fuel at that low of an altitude, it doesn’t disintegrate like it does at high altitudes so its a major risk to the city’s infrastructure
@@audify3833 you worried about infrastructure over human life?
@@dragonredsinbad4631 fuel dumping systems aren’t fitted to helicopters for the same reason that a lot of newer aircraft lack the capability, and it has nothing to do with the environment
Even if the helicopter did have the capability, I don’t think dumping fuel would have changed the outcome, as the fuel would not be able to drain fast enough
without auto rotate you will pass out before you hit the ground.
Can't believe this happens!! I assume the helicopter is in it's top condition ans the polite as well !! How come no safety 🤔?? So basically you are gambling with your life when you ride a helicopter??
If I m the millionaire I will contact Boeing to buy the AH 64 Aphache asking them to customize the Commercial Aphache for me then on one can assassin me by take my helicopter down.
Everyone can be survive this incident by take the AH64 Apache Helicopter because
1. the armed cockpit
2.The sealed it self fuel tank
3. Very Good fire extinguisher.
You will be survived from fuel tank blow up from ground impact but you can't take your sweet girl belong to you.
I came here to see an explosion. Was disappointed.
Fuck you prick
@@sm1ggy847 There's no reason for civilians to use helicopters, unless they are being rushed to the hospital. What I saw is, 'Look at me! I'M RICH!', then '(CRASH)'.
@@CooManTunes nonce
This is conspiracy theory, someone who well know about helicopter engineering did something with the helicopter and they know the timing altitude and forces that broke down the rear rotor machanism and the failure time was happened on the returned trip. The passengers and the crew had no chances to survive because the bad guys planed to burn everything by the fuel tank broke down from the impact.
Bet he had a lovely car he could have driven 🤣😂
