OK, 100% Proof … From Garmin’s own Simulator (runniung garmin Software – NOTHING to do with Flight Sims)
GNS530 should display LDA if it is a LDA
===
This is what MSFS displays
Calling it a VOR !!! and display the parameters as if it were a VOR
From radial & distance
But it’s NOT a VOR, Mr MSFS GNS530
==================
This is what the GNS530 MOD calls it (does a LOT better)
At least it calls it a Localizer, correctly like the OEM Garmin
Apparently, the SDK is lacking, in that you cannot directly get an Airport ICAO name from a nav Air at that airport. so the MOD does not current display KIAD
It looks like it is thinking its a ILS …though why ?
There is a Index of Approaches,
Approach type :[index]
0 = None
1 = GPS
2 = VOR
3 = NDB
4 = ILS
5 = Localizer
6 = SDF
7 = LDA
8 = VOR/DME
9 = NDB/DME
10 = RNAV
11 = Backcourse
So an LDA is a valid type …
So who knows what Asobo is doing … or how it is constructing airport files …
– but that’s as far as I am going …
