Until one of the two rotors fails then

if one if one of the rotor blades falls off or the rotor system separates from the fuselage, yeah. Otherwise tandem rotor helos have a combining gearbox that connects the forward and aft major rotor system assemblies, which allows both to be driven by one or both engines.
Their Achilles heel is they are a large target……..

As I understand it, this is also how the rotor system is geared on the Osprey.

I’m betting he exceeded sideward flight limits to start the loss of tail rotor effectiveness.
His cool guy sliding while turning approach looked well above 10-15 knots. Combine that with whatever wind speed was out there and he likely blanked effective airflow with the tail while simultaneously applying power for his approach adding up more requirement for the tail rotor to do its job.
Once he was into the low/no airspeed and spinning part of his approach he compromised with what control he had to bring the aircraft down in the least building/people populated place he could, because he had no altitude and clearance to simply dump the nose and get it flying again.

Wow! I had no idea you guys has so many limitations.
Didn't know tail rotor ring state was a thing.
Great video!
Thanks!
(rotorcraft are still weird)
That’s why it takes much more in the way of airmanship for helos than it does for airplanes.
Tail VRS is indeed a thing, unless you have a Fenestron tail rotor, or a NOTAR. Then it’s not.
Tail rotor, as an anti-torque device is constantly fighting the torque of the main rotor, as well as the lateral lift of the MR downwash on the retreating blade side of the rotor system. That’s a lot of demand that there may not be power available to accomplish, in certain temp/DA/weight situations.
Knowing your performance at all times, being aware of the conditions you’re operating in at any given moment, and having the situational awareness to understand the language the helo is speaking to you with at any given moment via flight control feedback……and heeding what it’s telling you…..are all paramount.

Airmanship?
Stick and rudder? except for a few bush pilots, yes
IFR skills? god no.
Had more helo guys try to kill me in fixed wing IFR.
What's with you guys and missed approaches?
airmanship. Exactly, as it comes to stick and rudder (or cyclic and pedal), airplane pilots are lucky they they don’t have all the various jacked up aerodynamic phenomena to have to deal with. They just have standard, normal stuff to deal with in that sense.
IFR skills. Depends on the pilot. Someone who flies light helo only and never stays current? Yeah, their skills perish. Pilots who work IFR regularly in the helos that are certed and equipped for same? As good as any other IFR pilots. Even easier since don’t have to worry about things like circling minima, or VDPs or the like.
What’s going on with missed approaches?

Flown with more than one rotor guy who ended up in unusual attitude on a missed.
Had to take the controls. One Army pilot, another guy who dropped water on fires.
I've kept an eye on helo guys ever since.
Don't get me wrong, I've flown with a few rotor to fixed guys who did rather well.

weird. I teach pilots that a missed is the same BAI flying that any other flying is. It’s not rocket science, it’s something you should be mentally prepared and reviewed for, and it’s only as difficult as the pilot makes it for him/herself.

Sounds like a lot of work. No thanks.

Bottom of the list
Maybe not unusual attitudes, but I’m fairly sure the jet airliner guys on here have said it’s pretty common for a missed/GA to be a bit of a goat rope even for them. Something about you don’t spend a lot of time doing 2-engine GAs in the sim and stuff happens really fast?
it’s not that difficult. Yes, a number of things happen quick, but it’s simple if the procedures are known, it’s expected (like it should always be), and its done by the numbers. Even easier in VMC. Some guys try to make like it’s rocket science for some reason.

In summary, winds from every direction and at any speed will cause your helicopter to fall from the sky.

Not intentional, man.
Dealt with AF, Navy, and certain "retired airline" types that had varying challenges.
With the helo guys.... weird flying machines makes for weird pilots.
(although i am really interested on you guys' take on the electric VTOL craze without wail rotors and autorotation)

It IS practice and the ability to recognize when proficiency has been compromised.
I've flown over powered and (grossly) under powered aircraft, and GA's for weather or other problem should not be an issue,
(I mean, it IS part of the job)
Single pilot guys seem to do better on the go.
Multi crew seems to have a comm lag exasperated by one person not keeping up.
(not always, but it seems to be more often)
Maybe the SE guys are just used to being task overloaded.
