I'm flying IFR flights via the Boeing 737. I have been utilizing real flight plans as posted on the Flightaware.Com website. One thing I noticed is that the jets there are flying much faster than the FMC has me flying which is roughly around 335kts. But the actual flight plans posted on the website has those planes (B737's) flying at around 400-450kts. Do I need to change a setting or two in the FMC, perhaps on the Performance Page?
not sure, dont forget that flightaware is a free service so the info may not be the most reliable in the world
