# Flight Crew Members > Flight Crew Members means professionals assigned respective positions to conduct a flight, including a pilot, copilot, and, if needed, flight engineer **Term:** Flight Crew Members **Last updated:** 2026-07-29 ## Definition ## What Flight Crew Members Means in a Contract Flight Crew Members is a defined term used in aviation-related contracts to identify the specific personnel responsible for operating an aircraft during a flight. It typically encompasses the pilot in command, the copilot or first officer, and, depending on the aircraft and route, additional roles such as a flight engineer or navigator. The definition exists so that parties to an agreement, whether an aircraft lessor, charter operator, airline, or corporate client, share a common understanding of who is covered by obligations, protections, and restrictions tied to flight operations. The term matters because contracts often attach distinct rights and duties to flight crew that do not apply to cabin crew, ground staff, or maintenance personnel. For example, a charter agreement might require that flight crew members hold specific licenses, undergo medical certification, or comply with duty-time limitations. By isolating this group with a precise definition, the contract avoids ambiguity about which personnel trigger particular clauses, such as those relating to qualifications, insurance, or liability caps. In practice, the definition is usually short but carries significant downstream effect throughout the agreement, since many operational, safety, and indemnity provisions cross-reference the defined term rather than restating the list of roles each time. ## How Flight Crew Members Is Defined or Measured Most agreements define Flight Crew Members functionally, by reference to the role performed rather than the employment status of the individual. This means the definition can apply whether the person is a direct employee, a contractor, or seconded staff from a third-party operator, as long as they are assigned to conduct the flight. The core roles named are almost always the pilot and copilot, with flight engineer and navigator added as needed depending on aircraft type and operational complexity. Measurement or verification of who qualifies as a flight crew member is typically tied to external standards, such as aviation authority licensing requirements, operator manuals, or manufacturer specifications for minimum crew complement. Contracts rarely attempt to redefine licensing or competency standards themselves; instead, they incorporate by reference the applicable regulatory framework and any operator-specific staffing policies. - Pilot in command, holding the primary responsibility for the flight - Copilot or first officer, supporting flight operations and able to assume command if needed - Flight engineer, included where aircraft systems require dedicated technical monitoring - Navigator, included for certain long-range or specialized routes ## Where Flight Crew Members Appears in Agreements The term commonly appears in aircraft charter agreements, wet lease and dry lease agreements, aviation employment contracts, and service agreements between airlines and staffing providers. It also surfaces in insurance policies covering aviation risk, where coverage terms may differ depending on whether an incident involves flight crew members as opposed to other personnel on board. Beyond core aviation documents, the term can appear in broader commercial agreements within the
