• 31 Aug 2021 (IVO San Diego, CA) MH-60S touched down onboard CVN-72. Experienced side-to-side vibrations causing main rotor to strike flight deck. A/C fell over side. 1 x recovered, 5 x missing
Sounds like ground resonance to me. I don’t recall hearing what the sea conditions were, but I don’t think they would have been too heavy this time of year in San Diego. Maybe there was another reason for (presumably) hitting the deck hard on one wheel?
One of the actual pilots here can explain in more detail, but from what I understand “autoland” isn’t actually as simple as the name would imply. A layperson hears that word and envisions the pilot pressing a button and then just sitting there while the plane lands itself. In reality, setting up an “automatic” landing is a lot of work in its own right.
Yes, it’s true that jetliners are certified for automatic landings — called “autolands” in pilot-speak. But in practice they are rare. Fewer than one percent of landings are performed automatically, and the fine print of setting up and managing one of these landings is something I could spend pages trying to explain. If it were as easy as pressing a button, I wouldn’t need to practice them every year in the simulator or review those highlighted tabs in my manuals. In a lot of respects, automatic landings are more work-intensive than those performed by hand.
Yes, you are both correct. There is autoland in airliners that has been in use since the 1960s and then there are emergency autoland systems that are more geared towards single pilot aircraft so that the aircraft can be landed by a passenger if the pilot becomes incapacitated. Airline autoland systems are designed for landing in fog / low visibility and require significant participation from the crew.
In general I think the whole pilotless aircraft thing has a similar problem to driverless cars. 99% of the technology is there but it may take a long long time to overcome the final hurdles. Single pilot airliners is easy from a technical standpoint, but there are still other issues to deal with around mentioned before such as adequate rest for the single pilot, protecting against rogue pilot events, and providing adequate support for the single pilot in the event of malfunctions.
I watched it 3 times but didn’t get a chance to record it. I only saw 1 statement that I’d call inaccurate. They said the MCAS was a safety feature. I’m not sure that’s an accurate statement. true it pushes the nose over if the climb out is too steep. It’s purpose was to mimic the flight characteristics of earlier models so that no additional training was required.
