July 1, 200916 yr Hi,I would like to know how (generally speaking) the MD11 flies an approach specifically regarding speeds and flap settings.I have checked the real Flight Crew Operation Manuals and the ones of PMDG. They provide a lot of info but not all.Consider the following data:LW: appr. 195 TVcl min: 206Vsl min: 167Vf15 min: 160Vf28 min: 154Vref35: 152This is how I fly the approach and I wonder if it is more or less correct:- Within 30nm of airport and at FL70 -> Clean config and 225kts (= Vcl min + 20)- Within 5 nm of intercept localizer -> 180kts (= Vf15 min + 20) and flaps 15- Intercepting glide scope -> 160kts and flaps 35- At OM -> Vref35 + wind corr.Is this a/the correct way.

You should be established at latest 1000ft AGL. Remember that if you plan a FL 50 landing- it will take a while for the flaps to extend!But flying more conservative is never a mistake:-) CU, Tom Morello- FSX SP 2, WIN 7, 64Bit.

Instead of FL15, I'll use FL28 instead next time.Egbert Location: Vleuten, The Netherlands, 17.3dme SPL 108.40 | Simulator: FS2024 System: AMD 7800X3D - Gigabyte X670 - RTX 4090 - 64GB DDR5 - 2 x 2TB SSD - 32" 1440p Display - Windows 11 Pro
July 1, 200916 yr Hi Tom,Thanks for your prompt reply.I understand that I can set speeds as low as Vmin + 5kts instead of Vmin + 20kts during (initial) approach phase.EgbertNo, you are correct to fly Vmin + 20kts in clean config, Slats extended and Flaps 15. The amber foot (band) will move to higher speed during a turn. The 20kts will give you an additional margin while manouvering/ turning (higher g-load= higher Vstall).The moving band is not simulated in the sim though!RGDSHi Tom,My last approach I did a 225kts clean and had a pitch up of about 6deg, which is pretty high. EgbertThe pitch will get as high as 10 degrees (high weight, with minmum speed with slats or FL 15). CU, Tom Morello- FSX SP 2, WIN 7, 64Bit.
July 1, 200916 yr Commercial Member Either fly faster than you're used to, or use the next click of flap (speed permitting).Be sure to pre-flight the FMS with minimum weight and airport data if you're not using the FMS to fly - it will provide speeds on the speed tape for slats/flaps/gear etc.., but unless you select an arrival runway, will NOT provide approach speeds for you.Best regards,Robin.
