Offsets for TOGA (MCP Thrust Hold)

Trying to assign Go Around buttons on thrust levers, and can't seem to find the offset that corresponds. Same offset which commands the thrust (n1) hold mode on the 737 MCP, haven't been able to track it down in the sysvar file. Any help greatly appreciated!

It isn't a pmSystems variable so it isn't in the "sysvar.txt" list. The main PM offsets list (in the PM documentation webpages) shows what you want as bit 21 in the DWORD offset 5412. It is labelled "THR" (after 747 practice I believe). You have to toggle the bit to emulate pushing the button.

thanks a lot!

Sorry, bit 21 in DWORD offset 5410 not 5412, of course.

In my code i only use 16-bit offsets for PM, so I had bit 5 in WORD 5412. I converted it correctly then typed it wrong!
