OiMS747 driver supports the Opencockpits modules: MCP, EFIS, CDU, COMs, and ATC.

MCP info and issues:

HDG rotary knob button acts as HDG Sel
HDG SEL button acts as HDG HOLD

EFIS info and issues:

To switch between RADIO and BARO make a long press on the MINS knob
To switch between IN and HPA make a long press on the BARO knob

Short presses of these knobs act as RST and STD.

As the RANGE knob has fewer detents than the virtual Range knob, not all ranges will be activated. 

The VOR/ADF switches do not work. Maybe in a later update if possible.

CDU info and issues:

Buttons reflect the physical placement you find on the B747 CDU. The buttons can be changed to better reflect the namings of the buttons by a user edit of the script.

COMs:

Shows correct frequencies, but standby values can't be set to the virtual standby display.

ATC:
Only knobs work to set the correct transponder code, the switches do not function.

To improve this driver, rksoftware must get feedback from you as a user for those things that are not working as they should. rksoftware will improve the driver if possible.

IMPORTANT NOTICE

This driver package will only work with Oi4FS v1.1 or better.
