Cheers Tonks... Another fact added to the library.

Fantastic explanation Tonks, thanks

I was actually wondering about pilots fiddling with differering positions....... - but you've put me straight on that!

[forthbridge]

Does make you think that modern tech is making everything boring.....not to mention making flight engineers redundant. I must admit, I saw the throttles at the engineers position but had no idea the FE actually operated them.....

[Erick_Cantu]

If you see the throttles all lined up you can be pretty sure that the pilots have the throttles When the Flt Eng has them he uses a gauge called a Synchroscope to make sure that all the engines are running at the same RPM... it uses No1 engine as the basis and has three other rotating needles to show whether the No2, 3 and 4 eng are rotating faster or slower than No1... if an engine is rotating faster its needle rotates clockwise and if slower.... anti-clockwise. If it is stationary the engine is synced with No1, and the faster the rotation the further out of sync. Helps with fuel efficiency and cabin noise to have them all aligned...

Hope that helps...

Not only that, but I once was told that the throttles' cables will expand and contract differently in differing temperature ranges, requiring different lever positions for the same throttle setting.

As to whether it's true or not, I don't know, but you don't see asymmetrical thrust levers in pictures of aircraft without actual throttle cables...

Similar but not the same as the 146 setup. Can't remember now if the final linkage was physical or electronic but to ensure all the engines were singing the same tune, they were set up to EGT (dial in the desired egt and the engines would go there) so the actual levers could be all over the place (within reason). Thinking about it.. this would probably make the final linkage electronic :think:

Well...... there is no quirkiness in modern day aircraft with throttles out of alignment or F/E manipulating throttles as can be seen by this shot (boring really ;-) )

The FADEC engine management came in with the RJ series, but I'm pretty sure many 146's were retro fitted with it.

[DaveB]

Thanks Ben. I find it difficult to consider the RJ as anything but a 146

Ditto Dave.

[Garry Russell]

Yep...............All 146's to me too

To me the RJ is that Canadair Challenger thing..but this is because I have a very limited number of brain cells and they all in use :roll:
