Actual AI autopilot is flying at TAS is 50 knots below what was set in the flight plan (default MSFS, but speed acceptable to me). The IAS is 30 knots slower than the autopilot set point, which makes sense relative to IAS, but don’t know why the AI is running it slower. Only 61% throttle, and it is clearly showing the autopilot IAS setting 30 knots faster than actual IAS speed, but it doesn’t increase the throttle. Makes no sense.
