Just wondering how the TOD is calculated?
I see on the ND a blue arrow (I think it was blue) which represents where the descent should start.
Why does the MCDU chose that, based on what exactly?
If we did not have that indication, how do we calculate when we should start our descent?
Descending down from FL300, following the STAR and being given radar vectors and getting cleared to intercept the LOC at 10 miles and 2000 feet AGL, how does one get himself to be sorted out so he doesn't have to increase rate of descent, use spoilers as I have been reading that can also be hectic with the VLS speed dropping low, etc.
Just a rookie looking to be prepared
Thanks all!
