HiPlease could you advise how to set the autopilot on the PMDG J41. The problem occurs when changing altitude. For Example: Heading is set to desired heading, altitude set at 10,000. ATC gives clearance to 16,000. I select ALT SEL and ‘dial-in’ 16,000, active the VS button and use the thumb dial to increase the VS value. At this point the plane will either go into a steep climb or dive and the autopilot will disengage. After re-establishing level flight, selecting autopilot simply puts the plane back into the dive or climb.Comments greatly received
