"Greetings folks, 1st off let me say I am pleased & honored to be a member of this group. I have a couple of questions that I am sure have been answered elsewhere but I have been unable to find them. 1st off, you guys have been very through with every aspect of the operations (which I am very pleased with btw) but I can?t find anything on cargo weights. Is it safe to assume that I can load as much cargo as I see fit given fuel limitations? 2nd, what is Global?s position regarding time compression? I have seen several threads where it is obvious some of you are not using it. My FS time is limited so my usual flight profile is thus. I take off & climb to cruising altitude at normal speed. Once at cruising altitude I go to 4X time compression. This is fast enough that it greatly reduces my time in front of the computer but slow enough that I can still monitor fuel & perform my CIVA updates. Once I get to the beginning of decent I once again go to normal time until I am at the gate. My only other option would be to fly in normal time & save the flight. Unfortunately this isn?t really an option for me because I like to use the CIVA INS. As I am sure most of you are aware when you reload the aircraft you lose all CIVA data. Any insight on the above would be appreciated Many Thanks! "

"Welcome on board! Regarding weight: unless specified for special charter flights you can take what you want. I recently learned that, in normal operations, cargos are not so heavy. I normally take 170 to 180Klbs and this is rather on the heavy side. Other opinions, colleagues? Regarding compression: you do well! take off and climb = 1x, we are limited to a maximum 4x once we reach cruising altitude and we go back to 1x on TOD (or before) Yes CIVA INS are great! Enjoy your flights cheers, "

"In another thread I did not intend to convey that all cargo flights are lighter than pax and sometimes they do fly very heavy. Often though, bulky cargo takes up a lot of space and is often not as heavy as people and baggage using the same space. I refered to the W&B manual and added all the max weight limits per cargo hold (including bulk). I end up with total of 208,541 Kgs. for max payload for the 747 classic frieighter. So it can carry a large amount of cargo if need be. The above numbers would not leave enough room for any fuel though but does show the max if all compartments were full."

"Thank you for the replies! I had hoped I was above board in my practices. I just finished my 1st flight from KLAX to RKSI & am amazed at how accurate the fuel burn is. My ZFW was 443K & according to my calculations I needed 331K lbs fuel to make the run. Well I fuel up & take off. About the time I am leaving American airspace over Alaska I start to take a hard look at my available fuel, fuel burn rate & remaining distance. I scratch my head & say ""Im not going to make it"" LOL. While I was cruising I was thinking about posting a message here saying ""HELP, what do I do?"" but I noticed as I continued my step climb & the aircraft got lighter I was burning less fuel. Long story short I landed at Incheon with 33k lbs of fuel left. I was planning on having 30k left. I love it when a plan comes together. <!--emo&:D-->[img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]<!--endemo--> It was an enjoyable flight! "

"Hi Bob, Interesting story on your first flight, thankfully it worked out so you can continue flying with us! <!--emo&:)-->[img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]<!--endemo--> Another option you have to extend your range beside finding the most favorable winds is to slow down, believe it or not. Usually you would cruise at M.84 and I'm assuming that's what you were cruising at. If you find yourself in a real bind such as equal time between (on this particular flight) RKSI and PANC (as a fuel stop) and you aren't sure you can make it to either airport, slow down to M.80. Your flight will take longer but the airplane is flying at greater efficiency. Justin"
