Chris,

Apologies, I misinterpreted the original post (and the title, it seems ::), not my day!) as concerning a usual descent procedure from cruise altitude.

I have just tested the CRZ DES function from FL360 to FL340, 94nm from T/D.
The screenshot shows -3000fpm, so this does violate the manual at page 443.

I believe another more minor issue here is the automatic scratchpad input of the new MCP altitude.
The scratchpad input is appearing only when increasing the MCP altitude above current cruise altitude, but not below such as in this case.

(757 III part 2, pg 344):
CRUISE DESCENT
Resetting the MCP to an altitude below the current cruise altitude causes the
new altitude to be copied to the scratchpad if the altitude change is 4000 feet
or less. The new cruise altitude can be entered on the cruise page.
---

I will file a bug report for the excessive descent rate.

Can you also reproduce this scratchpad issue?
When lowering the MCP altitude to the new lower cruise altitude, the scratchpad does not show it.

Thanks.
