Final answer:
The CE flight commander reports to the pilot in command (PIC), who has ultimate authority over the aircraft's operation and safety. The first officer, air traffic controller, and flight engineer are part of the operations but are not typically in the CE flight commander's chain of command.
Step-by-step explanation:
The CE flight commander typically reports to the pilot in command (PIC). The PIC is the individual with ultimate authority and responsibility for the operation and safety of the flight, who has been designated as such by the aircraft operator. The CE flight commander's role is to oversee the maintenance, and often the operation, of systems and components on the aircraft. Although they may interact with the first officer, the air traffic controller, and the flight engineer during a flight, the chain of command usually places the PIC at the top, followed by the first officer as the second-in-command.
It's worth noting that the exact reporting structure can vary by organization and type of operation. However, in standard commercial aviation operations, the pilot in command holds the highest authority on the aircraft.
