VASFMC Fuel Bug Fix

very-short

Members +
Hi Guys ,
Im a big fan of the free VASFMC software the sad part is that the last version released did have a fuel bug in it and it would hang when calculating the fuel in the INT page I have found the problem seems to be related to the flight plan waypoints so here is a possible fix that I have tried and seems to work well .the problem occurs when two way points seem to be to close to each other eg

The problem begins with the two lines I have highlighted ..... the waypoints seem to be too close to calculate the fuel required Thus causing VASFMC to Crash so a simple fix is to delete these two lines from the FP then re-save the FP import it into VASFMC . I have been doing this for a while now and it seems to work fine the fuel load etc is calculated and VASFMC runs fine pretty much 100% of the time .... I hope this helps anyone who uses VASFMC .... it was only by chance I stumbled across this fix but it seems to work I was able to narrow the problem down to the FP causing the problem because it was only sometimes VASFMC would crash so the only variable was the FP .

I hope this helps ,

cheers
