I fly the pmdg 737-800 winglet, and I use AS6, but when i fly my speed keeps taking these great decreases and then increasing again. My speed never keeps constant or at my cruise speed or at the set speed.This occurs through the whole flight, it stops sometimes when i disable aloft winds. Can u please help me, because it makes my flights horrible. How can i set up AS6 or FSUIPC or anything else to stop the problem?Thanks in advance!
