Thank you for your quick answer
I must explain thoroughly
When in radionav mode this value is the same as <0C48 1 NAV1 Localiser Needle: –127 left to +127 right>, but not in GPS mode>, but I need to get the value displayed on HSI in GSP mode.
I got a third party GPS device simulation for FS : reality XP GPS, that runs fine with FS and is more complete than FS GPS.
But I can't get data I need from this GPS device, for instance . The value given by FSUIPC (offset = 6058) is the one for the FS GPS, not from reality XP GPS.
So I thought I could get this error when it is displayed on HSI on GPS mode. That's why I try to read this value with FSUIPC.
Perhaps it is possible to get values from reality XP GPS (that's would be the best solution) ?
Best regards
