Fuel weight data disagree error

[pijnackerpilot]

Hello all, 

 

Today I did a Qatar flight from Islamabad (OPIS) to Doha (OTHH) in the A35K. I set up simbrief to take along a block fuel of 33000 which is plenty for this flight. As per OP, I loaded the fuel and payload via the load sheet. All as indicated on the OFP, generated by simbrief using the A35K profile provided by simbrief. After loading the Fuel and Load page (screenshot taken after being airborne for one hour), I already noticed that the required fuel enroute burn was significantly lower than stated below. 

The route includes a step climb to FL400 at TAPDO over the Persian Gulf about 2/3 into the flight. 

After take of I got a master caution and an ecam memo that states Fuel Weight data disagree. I followed the steps on the ECAM but all checks out. I don't know where this message is coming from. All checks out during the flight. Fuel consumption is according to the flight plan and I didn't have any fuel leaks

What is causing this error and why does it still impact landing performance even if all is good.

Additonally, on the STS page it states that BTV and autoland are now inop. Why?

I hope someone can help me out here on what is going on.

Thanks in advance.

Hmm not sure, is it possible something changed your fuel quantity during the flight? Did you use gsx to load and the correct fuel amount was loaded?

That might be the case. GSX was acting up the whole ground time prior to take off.

What is recommended regarding proper use of the OIC 'loadsheet' page in conjunction with GSX integration? In what order do things need to be done to do it properly?

I have no clue at the moment. I'm waiting for all the A350 and GSX integration bugs to be ironed out before I even install GSX.
