With you on that FSX.
There was no HOV mode or TU on this heli - I think that's only enabled on the SAR ac even though the buttons are installed. GA would only work above 60kts, but would give you a wings level climb at 1000' per min and accel to 80kts off top of head.
Ref rules Shytorque, by the sound of the metars and anecdotal eye witness reports then the VFR vis limits for a start AOC or none.
