Simconnect bugs at GPS WP NEXT ID and PLANE ALTITUDE,feet"

There is already one question about GPS WP NEXT ID that says one character is cut but my experience says that are more than 1. At my WPF application I load a PLN file with custom waypoints and simconnect is retrieving only seven characters when the name of waypoint is more than this length (wp1000m instead wp1000mm69 for instance).

Another recent bug is the PLANE ALTITUDE, feet that returns a value different from the one shown at the instruments. I say bug because my application was working well and both values were similar what does not happen anymore!

Thanks

Hello @novreis

GPS waypoint id simvars are limited to 7 characters.
Not sure why the PLN format allows more than that, this will be reviewed internally.

Your instruments will show INDICATED ALTITUDE, not PLANE ALTITUDE and those 2 can be different. This is the expected behavior.

Sylvain

Hi Sylvain, thks for your quick answer. Understood the first point but as you say you need to review the code because the PLN file is loaded and work well.

About the second point I am surprised because my WPF application was giving before the same numbers and now there is a discrepance of about 300 feet when the Indicated Altitude is 3000 feet.

I get 25xx at Plane Altitude. As I did not change my variables at my code I cannot understand why! Perhaps because I am flying at Alaska? I will try. at other places. Thks anyway

You need to adjust your indicated altitude for ambient pressure. If the current ambient pressure is different from the QNH set in your instruments, plane altitude and indicated altitude will not match.

Yes, I begin to understand that but at 3000 feet I thought that the difference would be not of this magnitude (almost 500 feet) . So I must adjust from the QNH that I must retrieve from ATC or other source. Thks
