August 5, 200322 yr Hi,Anyone knows hoe to make a VOR DME approach but automatic? Like you have GS in the ILS approach, you have FPA in the VOR APP and how to do it via-FMC. How do you intercept a radial in a certain distance automatically and not writing it on the legs page? Can we use the fix section of the FMC?Coimbra

Runway 01L has a DVOR/DME named ARL. In the chart I can see that for a VOR/DME approach my FAP is at DME 8.3 and I should be at 2500ft QNH, my heading should be 007 degrees. On the LEGS page on the CDU you type ARL007/-8,3 or if you'd rather like ARL187/8,3 in the SCRATCHPAD and line select the appropriate LSK. Set a hard alt on that point to 2500 ft. Enter /2500 and press the RSK correspoding to your WPT. The next point to keep track of is the OM. It's located 4.8nm DME and you should be at 1390 ft QNH. Enter ARL007/-4.8 or ARL187/4.8 as above and enter an alt of 1390 to this WPT. Last WPT is the MM but it doesn't have a DME from ARL so we can't use that one. On the charts for a VOR/DME approach you should have several points like the ones above listed in a table. And it's just to enter as many as you like. Follow these WPTs on the DES page on the CDU and you can see vertical deviation V/D, vertical bearing V/B or angle and vertical speed V/S. This should keep you on track. But don't forget to get heads up before it's too late. ;-) Hope it helps, Mats JohanssonPMDG Flight Test Dept | Asus Z270-A | Intel i5-7600K @ 4.8 GHz OC/H2O | nVidia Geforce GTX 1070 8GB OC/O2|
