CRZ ABOVE MAX FL without weights

[falcon71]

Hello,

I have received the CRZ ABOVE MAX FL message:

How is this message possible? I have not yet entered any weights yet:

The message was obviously correct, but at this point, the aircraft could not yet know its maximum FL. The display was correctly dashed on the PERF page. Is the message secretly using the actual weight instead of the weights entered into the FMC? I reported this issue a long time ago for the A300 and it was quickly fixed, I'm surprised to see it reappear here for a completely new product.

The A350 isn't built from the ground up, so it uses systems from previous aircraft. And yes, the A350 uses a mix of sensed weight and entered weight to calculate things, this is incorrect and not the case irl.
