I'm not sure this is any fault with OCS but was wondering if someone could offer up any ideas. Every time I fly lately. I seem to be 500' adrift. eg on controllers instruction I might set the altitude for 10,000'. On reaching what my instruments tell me, I the controller still keeps telling me to to go to 10,000'. If I then climb to 10,500' both my co-pilot and the controllers seem to think I'm at the 10,000'.
Is it my aircraft, or something wrong with my OCS do you think?
