How to determine Decision Height with FSUIPC and PMDG

[Eduardo Frontera]

468 / 5.000

Hello, good afternoon. My work environment is MSFS2020, and I use PMDG, as well as SIOC (Opencockpits), and FSUIPC. I'm having trouble representing the decision altitude (DH) as pressure (BARO). I use offset 04FA, but I understand that it only represents the DH values, but I can't assign new values with this offset. (Or I'm doing something wrong.) Is there another offset to write the DH value? Any alternative? Thanks in advance.

Then please post in the FSUIPC7 / MSFS support sub-forum, not in the main support forum. I will move your post.

As for your issue, I will take a look tomorrow now as I am just finishing for the day...

Offset 0x04FA is in an offset area assigned to Project Magenta (PM). Are you using this?
The standard Decision Height offset is  0x3428 (held in meters) and is read-only.
There is also a simvar called Decision Altitude MSL (Design decision altitude above mean sea level), also read-only, but this is not currently in any FSUIPC offset. You can add this to a spare/free user offset if required.

Normally, to set or change the decision height you would use one of the FS controls/events provided:

66321   INCREASE_DECISION_HEIGHT
66322   DECREASE_DECISION_HEIGHT
67412   SET_DECISION_HEIGHT
