C.J.

Jay only handled the controls during the repositioning portion of
flight. No passengers/customers were aboard during this time.

Is the C90 rated for single pilot? If so, anyone pilot desires can
occupy the right seat even a passenger or customer.

Turbo-props are all single-pilot if Part 91 (okay...FAA lawyers have at it).
The Cessna Citations 50xSP/CJ/CJ1/CJ2 are also SP with certain defined
equipment and a SP certification for the pilot.
