Cost index invalid?

Featured Replies

Hello all. I am about to embark on a delivery flight from KBFI to ESSA, and when I try to input a cost index the fmc shows invalid entry? Never saw this before. Perhaps it has something to do with the length of the flight? Or that I have a completely empty aircraft? Any help would be appreciated Adam

I tried 0, 20, 25, 30. Nothing worked until I finally changed the reserves from 2.0 to 1.0. Then I could enter a CI and after that I could adjust the fuel reserves Adam Kaleniak
