When loading different ILS approaches in X-Plane using the current database 2401, I see an anomaly that I would like to better understand and hopefully that can be corrected.
It appears that on many ILS/LOC approaches, the minimum altitude at the fix just outside of the final approach fix on the localizer approach is being incorrectly displayed on the G1000 FMS Flight plan page. Each of these intersections, just prior to the final approach fix, is incorrectly showing the minimum altitude for the final approach fix.
An example of this is the ILS 20R at Santa Ana, CA (KSNA). The minimum altitude over Hukem intersection is correctly shown on the approach plate as 2,800’ but the altitude that is being loaded into the FMS in the G1000 is incorrectly shown as 2,200’ which is the minimum altitude over the final approach fix of Lemon. See the attached approach plate and the G1000 flight plan page of the same approach which shows the discrepancy in the minimum altitude over Hukem.
A review of several other approaches in the Los Angeles area indicate this same anomaly is on many other FMS displayed altitudes over the fix prior to the final approach segment. See the ILS 25L at LAX or the ILS 30 at LGB for this same issue. It appears this incorrect altitude issue may be the way your database is being processing and displayed on the G1000.
I hope that this issue is able to be corrected so the displayed minimum altitude over the fix prior to the final segment of the approach is correctly displayed on the FMS display.
