Hpasp, three rather detailed issues on Neva:
2) can in real life a missile be launched when target is in RS only? In the sim, at least ASAP in angles is required, and in range you can hold on RS.
If you are going to implement moving the antennas by keyboard, a manual tracking (AS mode, now non-existent) can be implemented as well (e.g. when the switch AS-ASAP on the right is 'up' ('AS'), then missile can be launched even if the antenna is being steered manually in all aspects. I don't know if scoring a hit under such conditions won't require an octopus at the keyboard, but seems worth trying.
