290/.78 in th 757/767

This is changing with the next software revision of LIDO, according to a dispatcher we had on the jumpseat a couple of months ago. It was the default setting for the paperwork, but the new version will change with the cost indices.

.84 in the 757/767 seems awfully fast and very fuel inefficient (the 10-15 knot increase in TAS hardly offsets the exponential fuel flow increase viv-a-vis .815-.82). I know the airplane can do it because at Brand X we would speed up to .84 and .85 to race the three-eng/four-eng on the NATX for a few miles to get good photos of them. No wonder our 30W estimates had to be revised often.

It's seems out of ANC that FDX and UPS just about fly in formation to points in Asia. Usually, in the MD we cruise about .82-.83, but the other day we were time critical and had a CI of 555 which gave us .85/355. We did have to slow to follow our friends at FDX going into Inchon and it's good to know those folks have what I thought I read as a "hard descent speed" of 290 kts...please correct me if I misread the earlier post.

Thanks for the info.

How many years until that comes out <G>? I thought that they wanted the 290/.78 to get stay in trail with company, but if you think about it, is that really necessary all the way through mach transition in the mid 20's? I think that they are putting a lot of faith in that new spacing software that they bought. Should be at least as effective as the gantry was!

As an aside, I wonder how successful the high speed departure program out of Houston worked out. Out of STL, we used to accelerate to 320 out of 10K to help move the metal and during the last few years in existence we tried to construct a fix-balanced, departure schedule so as not to load up ATC with a constrant stream of departures over one particular departure gate.

I'm wondering as ANC grows in size, especially with widebody jets, if they will add more departure routes and more arrival routes. I'm usually half-awake, but I think it's around 400-450 miles out of ANC on the Amott6 that we start to get speed assignments for ANC arrivals.

IAH no speed limit seemed to work pretty well. I was flying a 727 and we'd clean up and speed up to 350. The only real problem was worrying about running out of the lateral limits of their airspace before reaching 10K.

Yes we have hats, but mine's too small for the ol cranium, so I keep it in my suitcase....
