Exception to second in command requirement: Approval for use of autopilot system

This regulation allows Part 135 operators to fly certain aircraft with only one pilot (instead of the normally required two) if the aircraft has an approved autopilot system and the FAA authorizes this in the operator's operations specifications.

To qualify, the autopilot must be capable of controlling the aircraft in all three axes (pitch, roll, and yaw). For commuter operations specifically, the pilot in command must have at least 100 hours of PIC time in that specific make and model of aircraft.

The certificate holder must apply to the FAA for this authorization and demonstrate that single-pilot operations with the autopilot can be conducted safely. The FAA may impose additional conditions or limitations when granting approval.

This exception doesn't apply where other regulations (§§135.99 and 135.111) specifically require two pilots, such as for certain IFR operations or aircraft types. It's primarily relevant for VFR and some IFR operations where crew requirements might otherwise mandate a second pilot.
