February 23, 201412 yr Quick questions for the community because I seem to be struggling with this. FMC setup, go to go there. Under 10,000ft I am disengaging the autopilot to fly my visual approach. Autothrottle seems to hold the speed well until I get on final. It doesn't seem like it is holding my VRef speed well at all. I consistently have to disengage, which results in a hard touchdown with high rate of descent because I seem to be floating it. On the MCP I have the A/T button alluminated with the speed in the MCP set at Vref+5 so around 142 or so. I am already in full landing setup with flaps at 30 and gear down. Where am I going wrong. In the FMC I do have the approach set at flaps 30 and vref of 137.
February 23, 201412 yr Do you have a throttle quadrant? If so then set it up in the FMC the way you prefer and then: 1)with the option: "Thrust Lever overrides AT - ALLWAYS" you have to constantly follow the PMDG throttles with your TLs even when the AT is engaged. 2)with the option: "Thrust Lever overrides AT - in HOLD only" you have to check your TL position only when the thrust mode changes to HOLD. (FLCH descend for example) 3)with the option: "Thrust Lever overrides AT - NEVER" you dont have to worry about the TLs at all when the AT is engaged. Rob Robson
