I strongly disagree with speeding up the sim-rate. Its just way to unrealistic. I have never ever done that. But thats me, you may differ. I have done lots of long haul flights. LAX-SYD, LAX-FRA, ORD-LHR, LAX-Tokyo, you name it. The best thing to do on a really long haul flight, (over 10 hrs.) is to do a night flight. Take off late at night if you want, it all depends on how late or early you sleep. After you have taken off, stay with it until you have reached your final cruising altitude, and make sure the planes navigation system, whichever you use, (I use the FMC with-PSS777) is set. Make sure the plane is heading ok, Plan your route. (When I have alot of time (Rarely
) I spend time to make a nice flightplan including plane, appx. crusing altitude and est. speed, flight depart/arrival info, etc...)Then once everything looks good, altitude good, speed good, navigation, set. Sleep or something. Just make sure you wake up before you need to descend.
On flights like 6 hrs., A good thing to do is take off in the morning or afternoon. Then you can watch the flight in progress whenver you want or can. This way youlll be able to land at around 6 or 7PM-or earlier, depending on when you start, or what your flight is. Hope these tips help
