FMC Throttle Control logic

Recommended Posts

Guest 19DK

Hi All,I'm seeing some behavior of the FMC which i dont understand when i perform an FMC Throttle controlled take-off and climbout. PMDG737NGDurring the initial climb(below 10K, hand flying). I see the the throttle control switch from N1 to Arm then to MCP A/S control, speed=260 even though i preselected MCP speed of 240 durring the preflight. FMC clmb page=250/10000 also.-Why does it default to MCP a/s 260?-Is there a document avialable that explians FMC Throttle control logic?Also, (durring enroute/app. transition) what causes an FMC "Overspeed Disconect"?Thanks,Tom D.
