No we don't, we use Kelvin or Celsius (I know this cause I do engineering) sometimes with thermo/aerodynamics stuff we even use Rankin.

I just had to look up the Rankine scale. It seems that American engineers, not satisfied with only Americans knowing °F, sometimes use another scale based on F, but using absolute 0 as its base, ensuring that even more people have no idea what temperature they are talking about. Just in case anyone was curious, it is about 510°R where I am today.

And generally most aircraft are equipped systems wise in Celsius, however, weight is still a toss up.

IIRC there was a plane that run out of fuel as the last airport used pounds instead of kilos, luckly the plane did not crash but glided to an airport runway safely.

Think it was the longest commercial jet that was gild.

I have watched way too much air crash investigation.

Rankine is the Fahrenheit version of kelvin

I find it cute that american scientists went so far to make a new absolute 0 scale rather than use what the rest of the world has been using.

If that was the case, pilots have to manually convert the two and so do the grounds crew and confirm between each other before and after refueling. Something I never knew until a few days ago when an Air France 747 parked right in front of our 747, and when the ground crew came to fill us up he was joking about how bad the other guy was talking and the first officers math was...

Anyways, I think I may have seen that one too, but I thought that electrical power went out, then both engines did, and both of those situations occurred at cruise...

Happened in 1983 but I remember that episode about this
 
Yup, knew it was a 67, just forgot the rest of the details. Interesting stuff though.

I bet a 57 would glide further though under similar conditions.

Eh it was off the top of my head, the important thing to note is...I remembered 👍:dopey:

They do use what the rest of the world uses, since in most cases Rankine is frowned upon in scientific journals and also American Scientist didn't create Rankine. It came from the same far off European shores as the scale Lord Kelvin theorized. Any who let's get back to the plane that is still missing and not devolve this into petty shots at the U.S. or what system of measurement is used by who.

Absolutely. I was only able to correct the spelling because I had no idea that Kelvin had a F counterpart and had to google rankin.

But, but, pot shots at the US and Fahrenheit are so fun.


Fine. Back on topic.

The plane is still missing.

I've worked on a lot of projects for a US company and I've never seen it, always Celsius. Fahrenheit isn't a centigrade and doesn't fit with either Celsius or Kelvin.

Just want to throw the data point in here that we use Fahrenheit primarily but most official documentations (e.g. specs, requirements, etc.) will quote both Fahrenheit and Celsius.

Yes but on actual projects in engineering (depending I guess on your discipline) I've never once used degrees Fahrenheit, and only ever used Celsius and Kelvin. Especially when dealing with Thermo and Aerodynamics.

And depending on the company.

I'm talking about what we do at my company on our actual engineering projects. All the actual engineering I've done involved using Fahrenheit and US Standard units unless I'm working with a non-USian.

That would be the first company I've ever come across in the US that would do that. What software are you using?

Personally, 500 Rankine is about the limit where it's going to be unpleasant outside without a metric-crap-ton of cold-weather clothing.

That said, I've been practicing my Celsius scale so my trips outside America don't sound so foreign when conversing about the weather.

And on the actual engineering stuff (research or projects) I do with other engineers that's not what we're told to use, since SI units are more universal. I don't doubt you have to use U.S. system stuff, but you're not the only engineer on these forums.

Anyways as I've said before can we get back to the lost airplane...which is still lost.

18 months has gone by, seems we are chasing a ghost, I still cant believe absolutely nothing has been found, which is extraordinary considering our state of technology,

Not really. As @LMSCorvetteGT2 said, the ocean is huge and largely unexplored. Don't forget that they are searching through 4km of water with no actual visual feedback, just the undulations in the seafloor.
Think of it this way, you dropped a staple on the carpet in your living room, and you have to close your eyes and find it using only the tactile feedback from a 6ft long stick that I give you. Good luck.

Ah, if only they were looking for a single piece of lego, in the dark, in bare feet. Much easier.

In seriousness there have been plane crashes at known positions in sight of observers on land where the wreckage has never been found. The chances of success for the MH370 searchers are astonishingly slim, sadly.
 
TDZdave
Search should have stopped a year ago,
Click to expand...
imo, yes, it's hopeless. I think the lead that the plane went west of Perth was a fools joke swept open by the media. Personally I still think it's somewhere near Vietnam and surrounding waters.

True mysteries never get solved, such as Amelia Earhart... So I don't see a reason to continue to follow in footsteps in which history has told us not to repeat..

Then how do you explain all of the data that puts the plane in the Indian Ocean?
Click to expand...
I'm sorry, but the search was never conducted over in the Indian Ocean extensively as it was west of Australia. If it were to be of interest enough, maybe.

But, I perceive the main reason as to why no search was conducted out there, would be due to the efforts required vs. what was required in Perth. The flight to reconnaissance area would be/is much shorter than the entire debris field hypothesized.

So far, no data on terrorists has been found, so the possibility of hijacking seems to be a no go on my list. The weather situations that were occurring what seemed like every week with air craft during peak storm season didn't help either.


In the aviation industry, and I assume in all transportation industries, the captain, driver, pilot is more concerned about his/her life, vs. those behind them. If it were to be a truly sick person (which nothing was found), then maybe yes, he'd deviate and drop it down in the water. But, I feel as if it went on the path shown from tracking software.
