Fuel Dump is too slow

[Pod562 0]

Hi,I have noticed that when I activate fuel dump on the PMDG 747 and it annotates that it will take 13 minutes until the fuel level reaches the specified amount, 4 minutes later, it says there is still 12 minutes to go etc etc. The whole thing runs slowly. I am sure I am following the correct procedures and would be grateful for any advice.How fast should the fuel be leaving the aircraft and why does the clock and fuel dump appear to run slowly?ThanksRenzo

Hi Renzo,The jettison time is initially estimated using a programmed rate by the computer, after about 1

To make a time estimate for yourself:Average dump rate is approximately 2000 kg/min.Harry

Thanks chaps but my fuel dump estimate is way off. 3 or 4 mins to drop 1 minute.Renzo
