I looked in the learning center for the cruising speed of the airbus A321, and it said .80 mach and 447 knots. I went into a free flight to test that. I flow at 1500 MSL so alltitude wouldn't be a factor in the IAS. The aircraft went over speed at about 345 IAS. Also i tryed putting .80 mach into the mach part of the AP and it said that was 500+ knots. I noticed problems like this in FS9. Is that learning center wrong or is there something wrong with the overspeed thing. What can i do to fix this?
