Part 135 SIC Pilots often work variable schedules, including early mornings, late nights, weekends, and holidays, depending on the company's operations and customer demand. Duty rotations can range from single-day flights to multi-day trips, and pilots must be prepared for short-notice assignments or changes due to weather or operational needs. Some employers use rotating schedules or on-call periods, which provide flexibility but may require quick adaptability. Pilots usually fly with a consistent crew or captain, fostering close teamwork in dynamic environments. It's important to clarify specific scheduling practices with each employer, as these can vary widely among operators.
