I remember long time back someone had raised this issue of adding "request descent" option. I know that we can ask for lower altitude but is it possible to ask for beginning of descent?
Those who use advanced airliners with FMCs, it calculates descent point based on STAR, speed and cost index. Although PF3 usually is accurate in starting descent, in some situations, descent is delayed. Currently, only way to begin early descent to match VNAV profile is it ask for lower altitude. Is it possible in future to add request descent option?
Thanks
