Problem: Missing Procedure Turn for LTCB RWY 28 ILS Z
Hello,
As you can see in the chart below, there is a procedure turn after the CI28 waypoint on this approach. For quite some time now, when performing this approach in MSFS 2020 with the PMDG 737, the aircraft does not execute the procedure turn. I also cannot see this turn on the ND. The chart, ND, and FMC screenshots are below.
On the other hand, when I perform the same approach with MSFS 2020’s stock 747, I don’t experience any issues, and the aircraft executes the entire procedure flawlessly. I’m also sharing the ND and FMC displays for the 747.
I assume it is a drawing issue on the ND because when you look at your legs, you see the outbound leg and the subsequent legs behind it. Not sure if you have flown it, but it should be flown correctly - it is only an ND display issue (which happens in real too sometimes;-))
The sequence seems to be correct in our data (and you confirmed it by yourself via the test with any other aircraft). The PMDG 737 series utilizes the “old” file format, which also has a few limitations. PMDG is working on a migration to the newer format, which they use in their T7 (2020 and 2024). Here, you can see that it is correctly displayed on the ND.
Great thanks for your prompt reply. Much appreciated.
Unfortunately, this isn’t just a drawing issue. I’ve tried this approach many times, and none of them follow the procedure shown in the chart. As seen in the attached ND, it continues straight up to CI28-4 and then returns directly.
I fly to this airport quite often, and this approach has been working flawlessly since the PMDG 737-800 was introduced. I wonder why it’s suddenly not working properly?
I think the image you shared is from PMDG 777. I recall it not working correctly there either, but I’ll check again.
You see the CI28-4 leg on track 052°; therefore, the leg itself is coded correctly, but the ND does not display this leg correctly (possibly it will also not fly correctly, I don´t know).
That is nothing what we have in our hands; we “only” offer the legs, but the interpretation of such sequences is part of the aircraft developer. Again, as I wrote before, the 737er series uses the old syntax for the terminal procedures, and here you have many limitations. The new PMDG T7 utilizes a more modern database, and here, the legs are displayed as you see them, but it also shows the correct path on the ND.
I know that PMDG is working on an update for the 737, which will also use the same modern database as for the T7. I´m pretty sure that they fix such issues, too.
