No problem Felix.

Bushbum,

Its very difficult to comment without seeing it in the flight deck with you. In this case if you are in VNAVSPD and you have not selected SPD intervention then the FMC thinks you are above profile. This would agree with your descent page. When constructing a descent the FMC will always plan an idle desent from the lowest AT or BELOW entered restriction below cruise and then work back upwards. With no other AT or BELOWS this means it will start from the hard numbers on the approach you have entered and work up. So if your tracks miles to landing are relatively short and you have some AT or ABOVE points in its going to show a high ROD to try and comply with both. In fact it will show ROD's which are greater than idle and require SPD brake.
