Describe the bug

In the cockpit preparation the planned ZFW is usually put in into the INIT B page WITHOUT the ZFWCG (because usually you get that with the loadsheet) in order to get first fuel planning values onto the MCDU. It is not possible here to input eg. "63.8" or "63.8/" into LSK1R.

Expected behavior

Should be possible to just put in ZFW with the ZFWCG to stay empty (amber boxes). This + blockfuel input should start the fuel calculation of the system

Steps to reproduce

see above

IRL experience with Thales, I think it isnt different here

Hi, this might also be a Honeywell/Thales difference, but according to this Honeywell manual, you can only modify the individual values once you've put them in together the first time.

[St54Kevin]

Why does it say 3R, isnt that 1R at the top?

[St54Kevin]

Oh disregard it means the FUEL PRED page. Hm okay so this really IS a difference then. Although it doesnt specifically say that its not possible

[BlueberryKing]

Apologies, that was the reference for after engine start. This is the correct section. I will say that the manual is not entirely up-to-date to the standard that we're modelling, so perhaps additional verification is needed.

[St54Kevin]

Yeah that manual seems to be very old, although I have not seen an up to date one. It is something I would have guessed to be updated by Airbus, so we need a Honeywell pilot to confirm

We have two different Honeywell pilots that have confirmed this in the past when it came up. It's only possible to enter ZFW only, if the ZFW/ZFWCG pair has been previously entered.

Okay thanks
