Hi kni-dk,

I have been discussing this with Jonathan at PM, they are currently very busy but will hopefully look at it soon.

If you buy the CP Flight MCP and EFIS control panel the "white" QNH works fine due to the code being correct within the CP Flight software BUT at present the storage of the "white" QNH does not seem to be saved in an offset we the general simmer can access.

I'm hoping this will change soon and I will post the solution when solved. I use Opencockpit hardware so that I can program it myself and I feel it is resonably priced. I've had a play with the CP Flight hardware, excellent stuff, but I cannot justify spending that much.

Regards,
ID.
