Hi all, Today I programmed a flight from EHAM(Schiphol) to EBBR(Brussels). Everything is looking good, the aircraft is flying perfectly stabil. However when looking at the CDU I saw that at the end of the flight I have to descent allmost 10.000ft over 16 nm ? ? ? Imho that would take 25-33 nm.... Any suggestions ? This route is flown at 12.000 ft. Thanks in advance.

Hi.

It is possible that you have encountered a small, but known, bug in the CDU. Using you picture with the CDU as a reference, I would:
1) Select the LSK L3 (CF25R) and paste it in LSK L2 (where ANT is).
2) DO NOT press EXEC, but press LSK L6 where you will see ERASE.
Doing this will, set all the altitudes to where they are much more reasonable.
