I know how to create a distance ring for any waypoint using the FIX page on the CDU. I want to create a ring that extends 30nm from TOD. Is it possible to do it easily and directly, or do I have to create a waypoint that's close to TOD and then assign the ring to that waypoint? I tried "T/D" and "TOD" on LSK1 but those are invalid entries, as I thought they would be. I've searched on Google and this forum, but have not found an answer. Thanks!

Hello all, I have recently started to practice cold-and-dark procedures and use the FMC more extensively. However, I have encountered a few vastly different issues: Mainly, I am confused about the use of VNAV PTH for descent. I am under the assumption that the FMC will automatically calculate the appropriate top of descent point based on altitude constraints, etc. and then automatically command a descent if the autopilot is left in VNAV mode and the MCP is reset to the altitude of the next waypoint prior to the top of descent point. However, when I attempt to follow these procedures, my B747 overshoots the top of descent, before beginning a terribly steep descent of anywhere between −4000 and −7500 fpm. Is this due to a procedural inaccuracy, or should I use altitude intervention to begin the descent before the calculated top of descent? In video tutorials, it seems that proper VNAV PTH use usually produces a vertical speed of approximately −2500 fpm. Secondly, is it normal that the B747 is slow to rotate during takeoff? Using the proper FMC-calculated speeds and trim setting, I am never able to reach an altitude of 35 feet at V2 (as recommended in the manual). Usually, I do not even make it off the ground when V2 is reached. Finally, the B747 has two noticeable inaccuracies regarding animations that (to my knowledge) have not been fully addressed. To me, the landing gear has always been the weak point of the visual model. The PMDG B747 has the tendency to "sit" on the gear regardless of how hard the landing was. The tilt of the gear (i.e., during lowering of the gear) should be independent from the pitch of the aircraft. Also, the behavior of the spoilers (when used for additional roll control) is slightly unrealistic. Similar to the gear, the movement of the spoilers seems to be tied directly to the position of the yoke (with no delay, presumably due to hydraulics). In real life, when spoilers are raised slightly for additional roll, they take time to sink back (modeled accurately on the QW B757 and the Level-D B767). It would be nice to see fixes (or revisions in the upcoming second version). Thank you for an excellent product and an extensive support forum! Owen Zhang

I have been flying the MD11 for about a year now without too many issues. Recently I have not been able to complete a flight with the MD-11. At first I thought it was a scenery issue but I recently discovered that it is maybe an MD-11 issue. Every time I am within 5nm of the Top of Descent, FSX will freeze and stop responding. I then have to CTRL, ALT, DEL and force close the program. I do not have the pause at ToD feature selected. I have also uninstalled, redownloaded the installer package and reinstalled the MD-11 and ran the FSX Registry Fix tool, all without fixing the problem. Any ideas as I do not want to uninstall and re install almost 400GB of programs. Jason Spiskey
