December 2, 200520 yr I have on any trip, more or less experienced radical changes in CRZ speed in high altitudes.Scenario;Flying Virgin 011 from EGLL to KBOS, climbout OK.. first stage of CRZ OK.. then.. when Active Sky refresh the WX and the winds.. the speed tape drops to 230kts IAS which makes flying hard.I have tried with wind smoothing ON, OFF.. I have tried winds aloft ON OFF.. I have tried alomst everything.. with the same result.How come this only happening in the 747 not in 737, nor Level D 767 or even PSS 777..Tips? (really wanna enjoy this baby 110%) THOMAS LORENTZEN | OSLO, NORWAY | i7 [email protected] | ASUS P8Z77 Mobo | 8GB DDR3@1600 | nVidia 580GTX | 1x Intel X25 160GB SSD for FSX | 2x 1TB WD | Samsung 204T 24" LCD HD | Coolermaster V8 CPU Cooler | Win7 64-bit|
