I find myself in the unhappy position of being temporarily (hopefully) medically disqualified (Kidney Stones).
During this period, I'm flying with an instructor, keeping my instrument skills (and quals) somewhat up to date. My question is, can I taxi my aircraft solo. Does it matter if the movement is not for the purpose of flight (for example, from the fuel pumps back to the hangar, or from the hangar to the FBO to pick up the instructor)?
