Microsoft's FS2004 looks impressive as in the videos this fellow worked so hard to put together. As far as accurately simulating 'the real thing', the helicopters lack any torque reaction whatsoever. Therefore, there is no need to apply pedal inputs for power changes, so no tail rotor drift ect ect. I do find this program useful for demonstrating ADF, VOR, GPS operations however. The frequencies are all accurate so a Canada Flight Supplement is most useful for radio navigation plus ATIS, Grnd and ATFrequencies. Also, I have yet to confirm this first hand but have heard that with a qualified instructor as part of a Transport Canada program, the MS Flight Sim program can be used for instrument time. I stand to be corrected on the latter.
