Not sure if this relates to the air pressure issue, seems to be a bit more than that would account for. A few days ago someone reported unusual flap effects, prior to the corrections to the YASim flight model.
It appears that not only do the flaps not increase drag in the 747, but they decrease it. Holding an altitude at 3000ft, with idle throttle, flaps position one clearly decreases the rate at which airspeed is falling. Going to flaps position 3 actually _increases_ airspeed (with throttle idle) and at the same time starts pushing the aircraft up in elevation. This is without the David's latest air density patch (using CVS from about 3:30pm Today 2002-06-05). Under the right conditions, not observed in a reproducable/reportable way (but generally lower airspeeds and altitudes) the aircraft can speed up drastically and skyrocket into the air at a rate over 10kfps.
