From Captain Sim support :Switches are to be found over the Captains FWD window (2D view ONLY), "INS Control Display Units" and "INS Mode Selector Units" are called out from menu Views -> Instrument Panel -> INS CDU and INS MSU.
Operations:
CIVA is connected with the 707 AP and FD.
To follow the CIVA track, switch ON HDG SEL on AP\FD control panel and push white GPS light/button on the 2D panel.
The CIVA will command heading bug on the HSI and FD on the ADI.
NOTE: We do not provide any support on CIVA software itself (i.e. installation, ops, configs modifications etc).
