Hi guys,

 

those of us who always try to enhance the realism of our flights will know that before every takeoff, the pilots will calculate a reduction of engine thrust to lower stress on the engines and reduce both fuel burn and noise. This calculation involves factors like runway length, wind, pressure, runway condition, slope and airplane weights, of course.

 

Now, there is one excellent tool for this - TOPCAT. But, it does only include the 737-700 and -800 variants - needless to say they are simply the most common ones. However, there are also some very interesting 737-900 flights that I would like to simulate as realistic as possible.

 

Long story short: Where can I find sufficient performance data on Assumed Temperature and Derated thrust on the 737-900?

I would also like to know this, i flew the 900 once and you can just feel the extra length in the fuselage as you rotate.

Where can I find sufficient performance data on Assumed Temperature and Derated thrust on the 737-900?

there is the data in the FCOM1 for the 738 & 739 ... unfortunately it's an incomplete extract from the (elusive / unavailable) respective FPPM's ... which i use as a "pro-rata" guide for the 739 to that provided in Topcat for the 738.

 

rough i realise, but i will remain patient in the hope the promised Topcat updates will soon be available for the ngx in all sizes ... and as it is to my knowledge, the only tool that considers climb gradients (as the FPPM does).

Maybe this can help you a little http://www.boeing.com/commercial/airports/acaps/737sec3.pdf
