I have swapped between Fixed Wing and Rotors throughout a large part of my career. My most varied day was to fly a piston helicopter, then fixed wing, followed by a turbine helicopter, for three different companies on low level ag operations.
I have never had a problem swapping between types. I do not have a problem swapping between my car, my motorcycle, or a truck either. They are all different and your mind copes with it because of the difference. I find myself more likely to make little errors swapping between two very similar types rather than widely disparate ones.
I have no special ability. I have just been lucky to have had the opportunity to fly such a variation.
