Alot of pilots don't use the FMC for fuel checks and just use the gauges instead.

What is the source of this statement?

http://www.pprune.org/tech-log/157821-737ng-estimated-arrivel-fuel.html

Sorry, it might be but I do not consider that a valid source for information on how to operate a complex aircraft. Now if you gave me the name of an airline check pilot then I would go "ooohh!"

Well those guys fly the real thing and what they say, is good enough for me! What do we know?

The fuel does get off a bit at times, but I've never really had an issue. If you're concerned, just add that 1-200kg. I doubt the sim models that behavior.

 

There is a known issue with the center tanks and about 500 pounds that mysteriously disappears. We usually show under burn and then it catches up. Not an issue, really. It's just how it is.

 

Don't worry about it.

Well, we don't fly the real thing nor are we real pilots except with some exceptions. Just use the PMDG and Boeing documents that have been furnished with the NGX. pprune stands for Profession Pilots Rumor Network. Keep that in mind when reading it.

 

And don't forget this post from 14 December 2014 by Scandinvian13 in another thread of yours on RVR/ILS - 

 

"While I'm sure you see this as "bringing good info to the table," the very fact that there are more than a few very knowledgeable people in here with many years in the aviation industry challenging this "good info" means that it's either not correct, or not being conveyed properly. This only serves to confuse people."

Yeah, anyone can sign up there, and if they seem at least partially educated on a topic, they could put off that they fly it. Granted, the success rate would be pretty low over there, because there are bound to be more people who actually fly the plane hanging out there to shoot you down, but the disadvantage of screen names is ambiguity. I can't verify if you do or don't, directly.

 

That being said, you also have to remember that a lot of guys out there think that their own OPSpec is what everyone else uses, which isn't actually true. Heck, I had two friends, who I know to be pilots/airline guys on my Facebook page trying to tell me that all people on the flight deck are considered crew members by regulation, and therefore cannot use PEDs in the jumpseat. They were mixing their OPSpec with the FAA. The FAA doesn't treat them (jumpseaters) as crew members:

"The FAA clarifies that the prohibition in the final rule only extends to crewmembers at a flightcrew member duty station; therefore, the prohibition does not apply to a person occupying the flight deck jumpseat.."

(Source: https://www.federalregister.gov/articles/2014/02/12/2014-02991/prohibition-on-personal-use-of-electronic-devices-on-the-flight-deck)

 

...though one could make the stretched argument that, since an OPSpec must be approved by the FAA, and is enforceable as if it were written in the FARs by that point, it's a "reg," but that's a pretty weak argument.

 

 

 

 

TL;DR: Always take what people say with a grain of salt. If you question what I tell you, you should question what they tell you as well. Nobody is perfect. I've been wrong plenty of times and I contracted with the FAA and have worked in the industry for over a decade now. Stuff happens. Ask for references. If they say "I can't post my OPSpec," that's good enough. It means that it's their own internal procedure. It might be an industry best practice. It might not be.

 

If one airline restricts pilots from using the FMC values, another probably restricts them from using the fuel totalizer on the EICAS. I'm not aware of an FCOM-prescribed procedure, which means that you're probably getting people asserting their OPSpec procedure is the "right" one. Admittedly, I haven't spent as much time in the NG FCOM as the 777 FCOM.

You have several sources on this forum that fly the real airplane daily yet you seem to constantly question the validity of the information they provide.

Fuel is your friend

Until you're on fire.

Haha yeh thats not well !!!!

Haha yeh thats not well !!!!

 

You have conveniently ignored post 98 by Joe Diamond which said "You have several sources on this forum that fly the real airplane daily yet you seem to constantly question the validity of the information they provide." Maybe you should reply to the post,

Have a pint mate and chill.

 

I never question the likes of matt c who flys in the RW. I may ask alot of questions that seems to validate, but thats no harm done
