B-737 Ng: Are Thrust Levers Fly By Wire?
 

Hi,

With no AC power, if we loos all electrical power after the 60 minutes off battery, do we still have the thrust levers working or will thrust stay at the last set?

Still working. You forget the EEC alternator. :ok:

Yes, all FADEC engines I know of are powered by a PMG, if the engines are running your thrust module should be responsive, may loose all indication but you should have control.

Loos.......Loose......What is the queens english coming to?

A language nazi, the most famous kind of internet posters...

Ah! Godwin's Law in action. ;)

I've said it before: Given that several thousand readers may scrutinize your posts, your respectability is somewhat determined by your proper use of the language.

That said, if English is not your first language, I'll cut you some slack so long as I don't have too much trouble understanding you. :ooh:

You only have 30 minutes of battery unless your talking about a dual battery.

The Queen is impotent and her language is lost....

People in glass houses... should check their grammar :E

As previously stated, there is no time limit on engine control thanks to dedicated alternators on the engines. If the N2 rotor/gearbox keeps spinning above 15%, I believe, there will be enough power for the EEC.

Just don't let the engines flame out in bad weather. With flat batteries, you won't have ignitor power to relight them (irrespective of EEC power).

Isn't the NG by default allways equipped with dual battery? Dunno really as all of ours are and we have a pretty weird mix.

(Oh, sorry about my bad english by the way, it is after all only a tertiary language for me.)

I think tango is asking if it is totally electronic ,ie no mech cables attached to levers ( ie airbuses), not so much that the eec will still be powered by the n2 genny or that the engine is fadec.

edited cos I was confusing/combining classic and new gen.

Power is set and controlled electronically tango so yes it is FBW

Hi Denti,
No, not all 737ng aircraft have 2 batteries.That, I am 100% sure of.

Ah, thanks for that piece of information, seems my alteon difference CBT is once again incorrect. Honestly wouldn't be surprised if you order a basic 737 without any options all you get is an empty metal hull, even the flight controls can be optioned...

Why is this question being asked here and not in the sim or at the company where flown?!:confused:

Great question, I think I will ask all my stupid questions at work and rant like a lunatic when not asking questions at work from here on out.

Hell, why google anything? there is plenty of resource material at the library..

“-Why is this question being asked here and not in the sim or at the company where flown?”

1) It was asked at the sim center owned by the factory of the NG. No answer!

2) If a forum, specially the Tech Log at Pprune.org, is not a right place to make this kind of question, I'm missing something!

Anyway, thanks for all the replays!

DC-ACHE wins the prize for stupidest and least helpful answer of the week and as ever there has been some robust competition. How often do you go in the sim? Do you save up questions for six months. As ever there is rarely such a thing as a stupid question, just stupid answers. All our Ngs are dual battery, I cannot imagine any sane person specifying single battery.

A lot of NGs flying around with only 1 battery:
- Most of the Aeroméxico NGs
- All of the All Nippon Airways NGs
- At least 1 of Southwest Airlines NGs
- At least 3 of Virgin Blue Airlines NGs
- At least 2 of COPA Airlines NGs
- At least 49 of Gol Linhas Aereas NGs
- At least 4 of Xiamen Airlines NGs
- At least 1 of Air Vanuatu NGs
- At least 2 of Hong Kong Express NGs
- At least 2 of Hong Kong Air NGs
- At least 2 of Hainan Airlines NGs
- At least 2 of Korean Air NGs
- At least 17 of Shandong Airlines NGs
- At least 2 of Hainan Airlines NGs
(List is not complete and configuration could be changed ;))

Like he said?:D
