All of a sudden I am unable to engage autoflight in the Learjet 45. I have done this literally hundreds of times, but not a single time today, or yesterday.
I thought all that was required was a valid Flight Plan prepared using the Navigation page, and engaging the C/P onscreen option by clicking on the On/Off and Route boxes, the two far left boxes in the lower right of the screen. I am assuming that I need to be headed in the general direction of the route and at a high enough altitude for Autopilot operation.
This no longer works for me. The NAV function is totally ignored as well as the magenta Altitude selection for the route.
Any ideas to get me back on track? I ran the valid file integrity check routine and had 14 bad files that was corrected by Steam and I then reran the check and all files are reported to be correct and valid.
