November 1, 201213 yr Hi All, Just a quick question - I know that TOPCAT can be used for flights with the 737-800, but what about on the -700 for working out take off power? Most of the time I've just been guessing but how does everyone else work this out? Many thanks, James James W
November 1, 201213 yr TOPCAT does have the -700 data, unfortunately its the wrong engine than whats on the PMDG, i think its the 22K engines, so the data will be a bit more than slightly off.

November 1, 201213 yr Why not use the FMC calculations? They take into account TO weights, winds, runway length/slope, temps, flap settings etc.

November 1, 201213 yr Commercial Member Why not use the FMC calculations? The FMC calcs what is, not what if. Derates and assumed temps are calc'd off of what if scenarios. For that, you need tables or TOPCAT to run the numbers of the what if scenarios. How would I do that? Would that give me the temperature to enter in? In order to do that, you go to TAKEOFF page 2 and enter the info, but this will not find derates/assumed temps for you. Useful, but not what you're looking for. Kyle Rodgers
