FMS calculations inaccurate
-
I noticed it several times, this time I took a screenshot. The FMS appears to have a hard time estimating times to waypoints/phases.
On this occasion, the ETA at the destination - about 100 NM further than the T/D point - was calculated to be at the same time... See the FMS.

I am now routinely checking this and can unfortunately confirm that this is always the case. The FMS is simply unable to calculate accurately. It regularly estimates the aircraft to reach the T/D - which is often 80-110 nautical mile before the destination - only 1-2 minutes before reaching the destination. Obviosuly, the closer you get the more realistic the estimation will gradually become, but this is not how the real FMS works. PMDG, Leonardo, Fenix programmed their systems to do very accurate calculations. I hope Justflight will refine this aspect, it is certainly more important from the pilot's perspective than to be able to play nice boarding music.
