Speed control during approach

[cniedzi 0]

Hi Captains.There is a mention in Ops section of PMDG web site concerning the speed control during approach:"Boeing pilots will be used to exercising manual control over the aircraft's speed during approach by using the MCP speed window. This is NOT how the MD-11 is designed. It is completely normal for the MD-11 to land with the speed window closed and under full FMS control.The FMS calculates approach speed on the basis of a few rules during the approach sequence, each distance listed is the point during the approach where these speed reductions must occur by, but they can occur earlier if calculations demand it. * 15 to 11 miles - Slats +20. * 7 miles - Dial-a-flap +20 * 6 miles - Flaps 28 +5 * 5 miles - landing flaps +5 The aircraft will automatically decelerate to these speeds provided you have the aircraft configured correctly as far as flap settings. You will see a hollow magenta circle on the speed tape indicating that it's time to deploy the next flap setting."Do you know where (in MD-11 documentation) can I found topics on this issue.R.Czarek

Hi,Could one elaborate more on this issue? When is a time to extend next flaps - examples with screenshots of speedtape would be great...RegardsCzarek

Hi, look for the open diamond, which is placed below the solid one when the FMC wants you to reduce. Jan-Paul

Hi,The solid dot is the currently selected speed.The empty dot is the FCP selected speed, not active.If you change the FCP speed and press FMS SPD within 10 seconds, it tells the FMS that the new speed will be what is selected in the window.Best regards,Robin.

Robin,You are right, but the same is for flaps speed control mechanism during an approach.R.Czarek
