well ones again, do not know why my first post has benn deleted. I have a problem with the NGX and LNAV and also Heading select at MCP.The autopilot is going from left to right and back to left around the magenta line on the ND and if I try to use heading mode on MCP he is going on any heading but not on theese which I selected. And also with 45° bank on FL 300 mach 0.78.I am using ASE and settings are as here: http://forum.avsim.net/topic/346862-my-new-weather-config-works-perfect-with-the-ngx/page__hl__weather__fromsearch__1 Best regards
