TOPCAT and the 737NGX

Recommended Posts

Bonjour,

 

I am new to TOPCAT and 737NGX, and I was wondering why the Mac% differs between them.

 

Finally I realized that when we enter the number of passengers in the FMC, there is an algorithm, which distributed them into the 3 stations in a random manner.

For example if we enter several times the same number of passengers, the FMC CG position is never the same.

 

So as this dispatch is not known and is not accessible through FSX variables, there is no chance to have the same MAC % between TOPCAT and the FMC.

 

Just want to know if somebody can confirm this.

 

Merci

Best regards

Claude

Bonjour Kyle.

 

First...  thank you for your answer.

I had already read this topic (TopCat + PFPX + 737NGX / Weights (How To)) but it is not very clear to me, concerning the MAC %.

 

Could you please, if you have a moment, enter in the FMC, several times, the same number of passengers, with the same distribution between first and coach class, and tell me if you always obtain the same MAC %.

 

Merci

Best regards

Claude

Distribution of PAX in Topcat and NGX is different, for one the NGX distributes pax a bit randomly, for the other, the actual size and location of loading sections is different.

Bonjour Peter,

 

That was also my conclusion, but I wanted to be sure as there was some people making specific configuration files in TOPCAT for the NGX.

 

In fact there is no chance to have them synchronized concerning the MAC %

 

Best regards

Claude
