In the bottom line, A:GPS WP DISTANCE is shown correct, as ‘DIS’ (13.2) in the first line of G1000.
Also bearing needle of HSI shows the correct direction.
It looks like you are comparing two different things.
Image 1 shows NAV1 set to IADQ but the navigation is being done by the GPS. The GPS shows the distance to FEGE as 13.2 nm which you say is correct.
Image 2 shows NAV1 set to IMOW and the navigation in the CDI is using the localizer. However, the localizer has not been “captured”. The first line shows the next waypoint is DG016 at a distance of 9.4 nm.
Whenever these types of comparisons are being made, it is necessary to use identical scenarios otherwise it is impossible to determine any problems.
You are correct that the CDI selection has nothing to do with the DME indication at the bottom of the screen. To display the GPS distance at the bottom line, select ‘PFD Options’, then for Bearing 1, rotate selection until GPS is displayed. This enables GPS as the Bearing 1 source.
The top image shows Bearing 1 has an “active” source for DME because of the green arrow pointer in the HSI. The bottom image doesn’t have the Bearing 1 arrow indicating no DME source.
Once again, in first line of G1000 NXI, ‘DIS’ shows distance to next waypoint.
Means, A:GPS WP DISTANCE seems to be used.
Even switching the buttons ‘DME’ or ‘Bearing 1’ does not help.
A:GPS WP DISTANCE seems not to be read from outside.
DME says: NAV1; 110.10 is in range of 20.6 nm. Correct.
Bearing 1 says: It is an ILS. Correct.
HSI shows a white circle, without an arrow, which should show the direction to ILS.
I will have a closer look at this problem.
None of this both problems you have with the stock G1000 from Asobo.
But this one is fare from reality.
