There is an interesting conversation going on in the thread about US pulling their IFE to save 500 lbs and the fuel to carry it (and the fuel to carry the fuel to carry it...)
It got me thinking. If the weight on the plane is slightly out-of-balance, do you have to trim it out (or does the autopilot)? Does the trim create drag and cost fuel?
In the airbus, we only set the trim for takeoff. Once the plane is airborne it trims itself. In the 737 and 757/767, you had to trim off the flight pressures as you flew with the trim button. Not sure about the 777.
Having the plane in proper CG is important for fuel savings, so United and others try to load cargo to maximize the best CG.

The pilots are way up high, and the nose wheel is below, but the NH pilots did a remarkable job of keeping right on top of the line.
No, not really. Once you learn how to taxi, staying on the yellow line is the easy part. The hard part is guessing where your wing tips are as you come close to objects.

I'm not sure on that, sorry.

No such call sign I am aware of. And of course nobody would really want that would they??? Sort of like the UPS "brown tail" call sign that lasted about 3 weeks in the early 90's.
I guess some pilots/controllers may slang it that way in a certain area, but I doubt "QA" would allow that for long. Probably just a combination of poor radios (your tax dollars at work) and rate of speech, etc

I definitely am not trained but do hear "air whiskey" on a regular basis ... now I'm curious to know what airline it actually is. BTW - I'm in/out of the IAD area and hear it a lot in this area
Thanks. Yeah, its my guess too - I'll just keep assuming they are the same
if you fly that area a bit, try seeing if you get passed b/w controllers and one says "AirWhiskey 1592" (for example) and the next retains the numeral but corrects the full call sign ("Air Wisconsin 1592").

On channel 9 recently their was a lot of reroutes being assigned due to stormes. The directions sometimes listed the same place twice in a row. What does it mean when they list the same place twice (back to back) in routings?
I've never heard of a clearance that listed the same fix twice. I would need an example clearance to know for sure.
Could it have been something like this? "...direct SUNNS, SUNNS3 arrival, ..." In that case SUNNS is a fix, the SUNNS3 arrival is a procedure which you will begin at SUNNS intersection.
A few weeks ago, A NW plane landing at MSP informed the tower that they needed to do an autolanding.
The weather was nice and the skies were clear. Why would they need to do this and inform the tower?

The autoland was likely for pilot currency. For many European carriers it's opposite, they have to make a point to do hand landings because it's SOP to do autolandings.
