February 22Edit

Boeing 777 range with 1 engineEdit

A recent news item [1] reports that a Boeing 777 had an engine failure. How far can such a plane fly on only one engine? I read the Wikipedia article, but did not see that info. If the engine failure had happened midway between US mainland and Hawaii, could the plane have enough distance to reach an airport? RudolfRed (talk) 01:10, 22 February 2021 (UTC)

Flying a twin-engined airliner (such as the 777) further than 1 hour away at its cruising speed with one engine failed from a possible landing field is known as "extended twin operations", "extended operations", or ETOPS for short: the concept has also been extended to aircraft with more than two engines, and usually refers to flights at least partially over water or remote land terrain.
Every civil airliner is given an ETOPS rating that gives the upper limit of the permitted flying time with one engine out that it is allowed to get from any airfield(s) it could divert to and land at. No flight plan should be made or accepted that breaches this limit.
The rating for the 777 was originally ETOPS-180: this was later increased to ETOPS-207 in at least some circumstances: bear in mind that as with most types of airliner, there are several variants with different capabilities. My extremely rough estimate is that this would translate to about 2,000 miles, but doubtless more knowlegeable responders can and will correct this. Of course, this is an indication of what a flight plan should stay within, not the actual capability of the aircraft, which presumably is somewhat greater.
According to various issues of Flight Magazine I read some years ago, airline personnel amongst themselves refer to ETOPS as "Engines Turning Or Passengers Swimming." {The poster formerly known as 87.81.230.195} 2.125.75.168 (talk) 01:56, 22 February 2021 (UTC)
Interesting. Thanks for the reply RudolfRed (talk) 02:10, 22 February 2021 (UTC)
Range is not affected as much as speed. As an example, I once opted to get two free round-trip tickets. I was in Hawaii, heading home to New York. My flight was on TWA. The jet had a broken engine. They couldn't repair it in Hawaii. They had to get it back to mainland. So, they told passengers that we could get free tickets if we flew back in the plane with one engine or we could wait for the next day's flight and fly standby. It may take up to 3 days of waiting to get back. Because there was one engine instead of two, the plane flew much slower, but had pretty much the same range. I discussed this many years later with an aircraft mechanic and he said that theoretically it would have the same range, but there are three circumstances that shorten it. One is fuel. Each wing is a fuel tank and you won't get all the fuel from one side to the other. So, there's some fuel that won't be used, shortening range. I personally think that is odd, but I'm not an aircraft mechanic. The second is that crippled aircraft are slower and fly lower. They are in thicker atmosphere, which increases drag, which lowers range. Finally, thrust from one side and not the other tries to turn the plane. The plane has to constantly be turned back against this to go straight. Again, that increases drag, which lowers range. He then told me that when TWA started, they had a test for the first aircraft. It had to fly from Kansas City to Denver on one engine to prove that if an engine fails, they can still make it to the next airport. 97.82.165.112 (talk) 11:32, 23 February 2021 (UTC)

Contact email for the company AlkèEdit

Hi,

So I'm not sure if this is actually a valid place to ask this question... but I thought I'd try it at least :) Does anyone know what the contact email for Alkè is? I looked on their website, and they only have a form for emails in the contact section... I want to just send them an email using my email client. If this question doesn't belong here, my apologies :) Regards, DesertPipeline (talk) 13:49, 22 February 2021 (UTC)

On several pages (e.g. here) they mention the e-mail address [email protected].  --Lambiam 14:46, 22 February 2021 (UTC)
Oh, hey, thank you :) I didn't think to check the privacy policy page – I only checked the contact page. Thanks again for your help :) DesertPipeline (talk) 14:48, 22 February 2021 (UTC)
Many companies avoid publishing their email address to reduce spam from email-address harvesting. Sending an email to [email protected] followed by the company website name will usually work. But filling out the form may work better by directing your message to the appropriate department.--Shantavira|feed me 15:15, 22 February 2021 (UTC)
When I couldn't find an email address on the contact page I tried sending an email to "[email protected]" – as you can imagine, that didn't end up working out :) Luckily the email address that Lambian provided was the right one and I got a response :) DesertPipeline (talk) 15:21, 22 February 2021 (UTC)

Enrolling in Moderna's new clinical trialEdit

How do you enroll in Moderna's new clinical trial of its booster that is designed to give more protection against the South African Covid variant — Preceding unsigned comment added by 67.253.78.55 (talk) 02:18, 25 February 2021 (UTC)

I searched ClinicalTrials.gov by the drug name mRNA-1273.351, with the result No Studies found for: mRNA-1273.351. Other search attempts using Advance Search (e.g. "Condition or disease: COVID-19; Other terms: South-African", or "Location terms: NIAID") did not yield applicable results. Nothing either on NIAID's Clinical Trials page or on the Messenger RNA (mRNA) Vaccines page of the COVID-19 Prevention Network.  --Lambiam 08:35, 25 February 2021 (UTC)

Bruce Springsteen caseEdit

In November Bruce Springsteen was stopped by US national park police and charged with DWI, reckless driving, and illegal consumption of alcohol in the park. This week he was cleared of the first two charges as his blood alcohol level was much too low to support them. (He pleaded guilty to the third charge.) Considering that his blood alcohol level would have been measured at about the same time as he was arrested, how is it that it took 3 months before the first two charges were dismissed? Is this just an example of a malfunctioning justice system, or was there some legitimate reason to leave the charges in place? --142.112.149.107 (talk) 08:58, 25 February 2021 (UTC)

No comment on the DWI issue and to be clear, I don't really know much about this case or US federal traffic law. But in most jurisdictions, you don't need to be intoxicated for a reckless driving charge to be sustained. Nil Einne (talk) 10:43, 25 February 2021 (UTC)
I don't know if it was malfunctioning, that's up to the opinion of whoever is deciding what "functioning" means, but in terms of how it is supposed to happen; once charges are filed it takes time for case evidence to be reviewed and for hearings with judges to occur, and for charges to formally be dropped. Since Mr. Springsteen is not the only person in the system, it does take some time for each step in the process to occur. It just takes time for a case to get on a docket and for the hearing to happen and for the decisions to occur. --Jayron32 14:08, 25 February 2021 (UTC)
It takes time if a court has to be involved, but from what I see in fiction, if a prosecutor decides to drop charges, that can take place immediately. And in this case it seems to me that that should have happened as soon as the blood-alcohol reading came back. --142.112.149.107 (talk) 00:02, 26 February 2021 (UTC)
Fiction is a word that means "a story someone made up". I.E., not the truth. You should not look to fiction for how things really happen. Sometimes, fiction portrays some things accurately, but that should never be your expectation. --Jayron32 13:19, 26 February 2021 (UTC)
I know that, Jay! --142.112.149.107 (talk) 05:52, 27 February 2021 (UTC)

I believe you are asking in the wrong place. This is an encyclopedia. You should contact whatever school this is about directly. JIP | Talk 14:15, 25 February 2021 (UTC)

Cap with bladesEdit

Hi,

(Sorry for my mistakes in English)

I sometimes see in American movies or cartoons people wearing a cap (baseball hat) with mini blades on top (like mini helicopter blades). It usually is a symbol of that person being stupid. The most common example is Ralf Wiggum from the Simpsons. My question is, how is it called and why is it considered as an accessory for stupid people? Is there an article about it? 59.153.254.82 (talk) 13:57, 25 February 2021 (UTC)

They appear to be called propeller beanies. DuncanHill (talk) 14:00, 25 February 2021 (UTC)
It's not that they are associated with stupidity (lack of intelligence), it is that they are associated with being socially awkward. Ralph Wiggum being both. --Jayron32 14:17, 25 February 2021 (UTC)
