INVALID PERF INIT UPLINK message

[CHEDHKG]

God day gents,

Since a few flights, in the PERF INIT page of the FMS, whenever I click on the  5R (Request SEND),
I get greeted back with the message : "INVALID PERF INIT UPLINK"

I tried to browse through the manual but found no reference to that error.

Would you know what triggers that and how to solve it ? (I can obviously enter all parameters manually, but sometimes I feel a bit lazy....)

Thank you

Hi, this occurs when the uplinked data contains any variable that exceeds its valid range.

Where is your uplink coming from? From PSX automatic generator or PSX manual setting or any add-on?

Thank you Hardy,

I use the PSX automatic generator, no plug in.
Here is my situ, if that helps.

Hardy,

Speaking of the PERF UPLINK function (which I love), briefly, how does PSX calculate the data contained within?

Of course it uses balanced field, but does it take into account the runway length and condition (dry/wet for V1 computation)?

I assume not, since this would entail lots of data and complex calculations but, being PSX, one wonders.

Thank you,

Mariano

Ched, your true ZFW is 279524 kg. The virtual dispatcher will blindly carry over that value for the uplink. In the FMC, however, the valid max ZFW entry is 270000 kg. Now you may ask why the virtual dispatcher isn't smart enough to limit the uplinked value. Firstly, it would be a dangerous lie as it's truly more than 270 tons. Secondly, this way you get the chance to see how that error message looks like :-)

Mariano, the virtual dispatcher uses the same algorithm as the FMC: Runway length? No. Wet/dry? Yes.

Thank you Hardy ! I guess I need some diet here.
