Previously the company used CI 30 on all B737 flights and a fixed CI in other fleet types as well. Fleet Manager - Chief Pilot did not understand that the CI should vary on a daily base. "Someone" else decided not to purchase that with the planning software. All CFP´s where made with a fixed CI 30. Sadly but true that was mainly because of the culture there.
Descend planning was .78/280 and changed in the FMC descend page.
In the present outfit we use diffrent CI´s on all Fleet and for each flight a new calculated one, that is reflected on the CFP and inserted into the FMC, the climb descend speed is also changed manualy according the CFP.
That speaks for A320, B737NG and B777´s as I have seen it lately.
Fly safe and land happy
