gsumner 6 Posted September 14, 2013 Share Posted September 14, 2013 Why is the takeoff speeds different. What parameters are important to get these figures to agree.Big question I know but I'm stumped.GrahamREX - 801839[http://files.100megabyte.com/ifly/media/signatures/Cockpit%20Buliders.jpg] Link to comment Share on other sites More sharing options...
FlightSimSoft.com 283 Posted September 14, 2013 Share Posted September 14, 2013 Can you give an example where you see differences? Link to comment Share on other sites More sharing options...

gsumner 6 Posted September 14, 2013 Author Share Posted September 14, 2013 Different v speeds on takeoff and my c of g is 30.0 but topcat calculates it at 26 ish. Also my t/o trims dont match. Everything is exported from pfpx so something perhaps weight distribution or something diesnt match. I dont know where to look for this disparity. Maybe in pfpx or topcat.

gsumner 6 Posted September 14, 2013 Author Share Posted September 14, 2013 On further reading of other websites it appears topcat information cg% trim and v refs should not be used for iFly cdu programming which is a shame really as it now makes it less useful/realistic than I'd hoped for.So is there anyway TOPCAT can be tweaked to show the same figures as the iFly cdu calculates.GrahamREX - 801839[http://files.100megabyte.com/ifly/media/signatures/Cockpit%20Buliders.jpg] Link to comment Share on other sites More sharing options...
FlightSimSoft.com 283 Posted September 16, 2013 Share Posted September 16, 2013 You would need an iFly configuration for TOPCAT. This can be done by creating a text file, telling TOPCAT how to load the iFly and where these load stations are located. Maybe there are already configrations available, reflecting the iFly specifications. Link to comment Share on other sites More sharing options...
gsumner 6 Posted September 17, 2013 Author Share Posted September 17, 2013 I have one of these files loaded but sadly it cant be accurate so im wondering how to tweak it. ThanksSent from my GT-S7562 using Tapatalk 2 Link to comment Share on other sites More sharing options...
