What an aircraft! I love everything about this except for one small detail, which I’m hoping other Typhoon pilots can help me with? The AP TRK will simply not hold the GPS course for me. Desired ALT and SPD are no problem. I can see my desired course on the map, and all WPT are listed. I see AP/AT lit up. I only bought this a few days ago via Aerosoft. Am I missing a step?
