my question is if it should happen at all because: In the other developers Boeing 747 QOTS II, and 777-200ERF, this doesn't happen with either an increase, or a decrease, in the altiutude selection.

Hi Mark,

Having just flown the other developer's aircraft, I agree that the scratchpad altitude does not display in the 747 QOTSII. In the provided FCOM, cruise climb/descent is said to be performed by the altitude intervene switch (and also in the 777ERF).  This fills the altitude field automatically on the VNAV cruise page.

Since the 757/767 does not have a push button on the ALT dial, I assume the alternate method Boeing used for "automatic" input was to copy the altitude into the scratchpad.

I will file a bug since the manual states it as a feature, and it is only partially implemented as it stands.

Thanks.
