Things I've noticed:1. Changing the Cost Index doesn't do anything as far as I can tell. It should change the climb, cruise, and descent speeds. The higher the Cost Index, the faster the plane should fly.2. The fuel estimates for TOD are way off the further the a/c is from the TOD. As you get closer to the TOD, the estimate continually increases and is finally accurate only when reaching the TOD point.3. It's not possible to enter a waypoint AFTER the arrival runway. This is necessary for inputing the Missed Approach fix.Thanks,James

1) No, it's not simulated, whatever you enter it woll give a cruize speed of Mach 0.7552) This is a known issue, pert of the erroneous VNAV calculation.3) I think this one is also a known issue, I'm not sure thoughBest regards//Mike
