I tend to use the accelerated time for cruise and I have noticed a few problems.The FMC has always got confused about the fuel plan when you use X4 or greater time. Saying insuficent fuel. I don't necessarily mind this when you return to normal time it stops panicing.After the update however I have noticed the new clock ET time does not run at accelerated time, but remains at x1. This is rather more annoying.Just out of interest, but just how badly does accelerated time ruin the fuel plan, time/distance things anyway?Flying long flights is just simply boring when at cruise, even though the flight and fuel planning is more interesting.Thanks.

Hi-the clock is based on PC time, so no accelerated cruise is supported... Sorry!

But it appears the actual time is FS time and advances with the accelerated time, it's just the ET timer that doesn't.
