YMML Melbourne to KLAXFS9 ran for 21 hours. I need to look at the duenna and determine how long it was paused at Top of Descent.http://www.fsrtwrace.com/track/ShowFlight....plGDvMMTRqobfQM

I thought I'd try that also Buzz...Here's a 17hr flight from YSSY Sidney to JFK. Not much fuel remaining. :(

holy crap how did you get from sydney to jfk in the pdmg 747?? ive tried that leg a few times and ran out of fuel mid flight.:)

Hi Eamonn,I had very nice winds coming out of Sidney (30 to 50kts) and you can see over the U.S. what the winds are like now. It wouldn't have been possible w/o. those winds. I am terrible about documenting things... the estimate for fuel remaining hovered around 7000lbs going as high as 10,000 after hitting the States. That is probably where it ended up between 7 & 10 (total).Cost Index of 100. Initial Cruise Altitude i think was FL370 which I stepped up to FL390 before going to bed. Woke up to step climb again to FL410 then FL430 (as soon as it was recommended). I don't think there was any difference between using Econo Cruise & LRC (seemed same airspeed). Thrust limit for Climb was the default setting.Fortunately no FMC messages until after I got up. That required opening up the Op Manual for "Abnormal Procedures" to make sure I was setting the Fuel Pumps/Valves correctly.

Makes sense.. :) Now try to do the reverse.. LOL KJFK - YSSY.. Did you have an empty bird or did you have PAX and cargo?Thanks,

Actually Eamonn,My first try was JFK to Melbourne. I thought if I kept climbing, I could top those fierce headwinds. :( After 2 hours I conceded it just wasn't going to work and put down at Columbus, OH (KCMH).Btw... No PAX, No Cargo. Just a "flying gas can." :(

I had PAX and could not get above FL300 for my initial cruise.I want to try KJFK to Beijing.

You can easily fly a fully-loaded 744 KJFK - ZBAA trans-polar 5,942 nm: Max range at MTOW is 7,260 nm. Cheers, - jahman.

I am going to have to give that a go just to do it.

Not with the 74F... a "comfortable" distance (i.e. w/ reserves) w/ full cargo & pax (about 123 tonnes) is a hop across the pond like JKF - Stansted.And a quick check w/ the PMDG Load Mgr shows trying to load the 744 w/ max Pax & Cargo about 20 to 30 tonnes over ZFW (depends on variant). Where's Steve Bell or Snuffy when you need em!

Not with the 74F...

Yes, that's why I posted "744" and not "744F" Cheers,- jahman.

Yes I know what you said. My point was, with the 74F... it has a higher ZFW than the 744 (putting the load closer to your "You can easily fly a fully-loaded 744 KJFK - ZBAA trans-polar 5,942 nm")... your 90 - 100 tonne load just won't happen in either aircraft for KJFK - ZBAA.So I am still not sure why you posted "744".

I meant at MTOW. Apologies for the poor wording.Cheers,- jahman.

Check this B-744 long-distance flight: London to Sydney, 9,918 NM in 20:09! (See here at 2:06).Cheers,- jahman.
