Hi Guys,
Sometimes on some flights you will have different tropopause heights on your SIG charts, now entering it into the FMC depending on the weight seems to affect your optimum altitude calculated by the FMC, but how does it behave if your route is crossing different tropopause heights. and how much really does the entering of the tropopause height into the FMC affects performance??:confused:
