Group 1 In-Flight Functional Check can be conducted by which group?

• A. Any Crew
• B. Only Dispatch Personnel
• C. Ground Crew
• D. Maintenance Engineers

Answer: (A)

Group 1 In-Flight Functional Check is about who is authorized to perform a basic in-flight verification of systems. It is designed so that any trained crew member on board can carry out the check, rather than tying it to a specific ground-based group. The idea is to enable quick confirmation of normal system operation during flight, ensuring the aircraft can continue safely without waiting for ground personnel. Dispatch personnel and ground crews aren’t on the aircraft during flight, and maintenance engineers typically handle more extensive tasks on the ground. Therefore, any crew member who is properly trained is able to perform this in-flight check.
