I am searching for off the shelf instructor software that will perform several functions. I am using MS X software for a helicopter trainer. The main functions I need are: The ability to introduce instrument failures Flight planning Pause flight and fast restart of mission manually reposition aircraft when sim is paused. System Failures Receiver failures I am asking you as you are an expert and probably have a clear idea what shareware or for sale that can perform these functions. Best to you Dean
