Descent speeds
I got it.
I think you're correct, Wizofoz. But we have to suppose the descent speeds in the manual's tables are made for higher weights.
If the speeds in the tables are for greater weights, so off course the glide distance will be larger for increased weights.
But, doesn't the FMS calculate the best descent speed for a give weight? And for ECON descent, it calculates the best speed for a given fuel versus time cost, right?
Thank's!
