Confusion about Topcat transferring data

Recommended Posts

After completing all the steps to prepare the 737NGX for flight, I press the "send" button. Topcat goes through the transfer process (blue progress bars) and reports all done (except for fuel and payload).

When I check the CDU pages none of the info has been entered, I have checked and rechecked my work, correct plane, etc but still no joy.

Topcat forum is read only and no info there.

Can someone get me on the right track?

Help greatly appreciated:

Best regards to all,

Neal Howard

Neal:  TOPCAT does not send takeoff/landing data to the aircraft.  It only sends weight and balance to the aircraft.cfg and, as you implied, that can not be used with PMDG.  Just make a note of the flap and v-speeds and compare with the FMS calculation.

Thanks downscc......I guess the only value of Topcat then is to get the calculations and manually enter them. Obviously I misunderstood the function of Topcat when I bought it. Oh well, brain cells do die.

Actually it is because the payload and fuel model of PMDG is rather complex that you cannot use all the functions provided by Topcat, but they work with some other addons.

All depends on what you fly with.

I would suggest you buy PFPX and topcat integrated with that also you can get weather from your ASN

You did not waste your money. Just the takeoff data of derates, assumed temperature, flap settings and V speeds is worth the price even though these settings can't be automatically be transferred to the NGX

Actually it does send weight and balance data to the aircraft if FSX is running and the aircraft is loaded. Not V speeds and thrust though as you said. TOPCAT has send and save options, the latter writes to aircraft.cfg.
