My 737 NGX is working good. . When I use the cold and dark tutorial for start up it works perfect. As long as I am using ground power. However when I try a start up using the APU I cannot get the speed bugs to transfer to the speed tape and the warning No VREPs does not disappear. Now I know it has something to do with the packs. And they can also be deleted by using a fsx key to release the handbrake. But this happens and the aircraft has not moved. . I have also tried with the packs on auto and off . . But the bugs will not transfer. Being well on the wrong side of 70. I know it is me. But I am dammed if I can see what I am doing wrong. Help..
