The plot thickens
.
KMTN is a RWY 33 Intrument approach.
The charts for it are LDA RWY 33
Localizer is 232 deg
Runway is 315
so a 6 degree Offset
But in the Real world Garmin GNS530, it displays as
IMTN
KMTN
ILS 33 ( Not LDA 33)
even though the LDA 19 at KDCA displays as LDA 19
So when is a LDA not an LDA , and an ILS ???
The more you look at this, the more “confusing” it gets !!!

Answer: Database in the Garmin Simulator is OLD.
Back then the RWY 33 was an ILS.
Now is considered to be a LDA.
Now the question is How old is the MSFS database … Old = ILS New = LDA
Always something new to learn …
