Hello When fuel and weight planning also using Topcat do we take all aircraft weights ETC from Fcom for the PMDG 737 800 NGX, I know thats probable any obvious question just want to make sure PMDG FCOM can be used to faithfully fuel and weight plan Wayne

It depends on the livery you are using ... the numbers in the FCOM is for a 737 without options ... you can buy options to get better MTOW and so if you pay for it.Some of these liveries have those options and its quite obvious in some cases (like 10tons of taxifuel because max GW is 10tons higher than MTOW).But you can use these numbers, its not 100% accurate but you can life with it

thanks what do you mean by livery, I am using the 800 with winglets Wayne

there is the PMDG, Southwest, United Airlines, Ryanair and the other ones you can download ... and they have all pretty much different weightnumbers, but you can mostly ignore the differences http://www.precision...s/liveries.html they have the numbers from the Real World airlines, so if one airline have bought an option to have higher weight limits, its also in the livery

good to know I thought it was just a repaint Wayneok i see thanks very much

its more than just a repaint, even the instruments they are using are replicated in the liveries ... do they have eyebrow window in rw ... then its also in the livery ...collins or honeywell mcp ... like in rw and so on :)
