Hello!

Looked everywhere and I can’t seem to find the answer…when in the Takeoff Ref page of the 787 CDU, I can’t enter negative temperature values…it simply says “invalid entry”. I tried, for example, -4, -04, -004, /-4, /-04, /-004 with no success.

Is this a known issue?

If not, any guidance would be appreciated.

Cheers!

You can enter negative values for OAT on page 2. On page 1 you can only enter positive values for Thrust but I’m not familiar with this entry.
