This is a systematic observation and recording of FS data every 2,000 feet as the models climb to high altitude. In each case, IAS was set at 250 kts below 10,000 feet and 285 kts above 10,000 feet.

There are some which: a) Have insufficient power at higher altitudes, :( Have thrust scalar increased to compensate for lack of high-altitude thrust, often making for unrealistic operation at lower altitudes.

November 16, 200223 yr How realistic are these models when compared to the real thing? Also, how does the 767PIC compare?Thanks,Robbie
