Dave,
On the other hand, the control of some of the functions required for tasking is getting simpler, therefore making it easier for a pilot to control.
eg. .Mapping, whereby GPS co-ordinates are fed to a laptop, currently doen by an observer sitting in the helicopter. Quite feasible that the inputs could be remotely controlled by the pilot, and probably more accurately since he wouldn't have to interpret the observer's instructions
Filming, where stabilised turret cameras are now easily controlled from a remote on the collective, and linked back to the newsroom.
Winching, once upon a time, could be done by the driver using remote switching on the collective. Time has seen this function better carried out with multi crew...
