PMDG 73H. Need help please :(

[Guest swadeep]

Hi i fueled up about 37 percent and anyway when entering my cruise level.It says OPT FL is 430 and max is FL429. That is wrong and doens't make sense. Does anyone know why?And also on FMC when i click 0 it shows 8 instead!! And also the same with 4 and 7.Please help. Really want to fly it.Thank YouBest WishesSwadeep

What cost index are you using? FYI: The FMC is calculating the recommended optimal flight level. You can fly at any appropriate flight level you wish.

Not sure why it does that but on the real machine it will never give you above FL410.

Hi. I put 100 as cost indexI know but it's weird that OPT FL is more than MAX FLI know that we can fly at any FL we wish but still OPT FL shud be less than MAX FL.
