3.rd CDU in Pedestal

After having changed the main CDU´s from FDS to Simworld, I sold one of the FDS-CDU´s. The other is now mounted in the pedestal. This ofcourse is a very unusual setup for a B737-800. Maybe some B737 businessjets have it for longe range cruising . However, it turned out to be very useful together with Vatsim´s Vpilot. Vpilot can be controlled with the CDU via Humbertos Prosim Utils.

This way, the normal flow for the main CDU´s can be kept, while all Vpilot, but also other ACARS information is going through the 3 rd CDU. It is configured as standalone. I noticed, it is therefore not switched off in cold and dark.
I now managed to make a lua, that starts a batch for starting and closing this CDU depending on AC-power state. That works even when power is switched between AC-power sources. The CDU goes off for 2 sec. and comes back then.
