Still using "non pro" mode for evaluation. Having a couple of speed issues.

1. In AP-NAV mode at cruise altitude, indicated waypoint TAS is not achieved. e.g. FMC waypoint indicates TAX 455kn/FL360 - Aircraft climbs to FL360 but remains at 235kn.

2. When taxiing, the aircraft will accelerate to 40+ Kts even with the throttle reduced to idle. Have to keep tapping the break to slow down. Am I missing something here?

I'm also really struggling with pitch/airspeed on final approach, even with full flaps and gear down. Seems very hard to slow down without leaving the spoilers deployed. Any tips?
