A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Pilot error is rarely the actual cause, but is a convenient scapegoat. I worked in rotary accident investigation in the Army and that’s not something you’ll read in a report. There’s other issues; why is this aircraft in particular so prone to pilot error? Perhaps it’s poorly designed?
It's because it's a heavy rotorcraft. Not poor design, just rotorcraft physics. It's prone to enter a vortex ring state if the descent rate in relation to forward velocity is too high. The same thing can happen with any normal helicopter, but the V-22 has a lot of weight for the disk area of it's rotors, giving stronger vortices from the rotors.
It's a pilot training thing, but I think they did put some sort of alert system on it if it's getting close to the conditions that induce VRS.

Like I said, poor design. Wrong tool for the job.
It can’t travel slow enough for blackhawks nor fast enough for fixed wing. The V-22 is an absolute turd.
I thought they were designed for things like marine search and rescue, where speed is important and the ability to hover is essential.
They're great at this, but the pilot needs to stay within the operating envelope, same as any helicopter.
All rotorcraft are dangerous compared to any fixed wing aircraft. It's a lot less forgiving on pilots and maintenance crews.
Well, they’re not fast (prop too big) nor are they particularly great at hovering (rotor too small).
It’s the worst of both worlds.
They're faster than any conventional helicopter, right?
Yes, but slower and less range than fixed wing. Likewise, it can’t do rotary wing things as good as a helicopter. It’s truly a “master of none” aircraft. It’s not great at anything.
Putting it in a rescue role is a terrible idea. You do not want a finicky to fly, unreliable aircraft in that scenario.
Read all the links, it's nothing unique to the V-22. All rotorcraft suffer from the same condition.
Pilots just have to be careful while descending with low forward velocity.
I repeat - tiny heavily loaded rotors are the wrong tool for the job thus making it a bad design
