Two Pilots, One Mission
In every multi-crew flight, teamwork is everything. While both the captain and the copilot (also known as the first officer) are qualified pilots, they each have clearly defined roles that help ensure safety, efficiency, and clarity during all phases of flight. Understanding these responsibilities is key to maintaining proper crew coordination and avoiding confusion in high-stress situations.
Captain: The Pilot in Command (PIC)
The captain holds ultimate authority and responsibility over the aircraft, the crew, and the safety of the flight. This position isn’t just about flying — it’s about leadership, decision-making, and accountability.
Main responsibilities include:
Making the final decisions in all operational matters
Ensuring compliance with aviation regulations and company procedures
Managing the crew and maintaining discipline in the cockpit
Leading in abnormal and emergency situations
Communicating with ATC, dispatch, and ground personnel as needed
Conducting the pre-flight briefing and delegating tasks appropriately
The captain usually sits in the left seat and is designated as PF (Pilot Flying) or PM (Pilot Monitoring) depending on the flight leg.
Copilot: The First Officer (FO)
The first officer supports the captain and shares many of the same operational tasks. They are fully licensed and trained to operate the aircraft and are prepared to take over command if necessary.
Key responsibilities include:
Assisting with pre-flight planning, walkaround inspections, and briefings
Operating the aircraft when designated as Pilot Flying
Monitoring instruments, flight path, and communication when acting as Pilot Monitoring
Reading checklists, managing systems, and making callouts
Taking control if the captain is incapacitated or delegates command
The copilot sits in the right seat and plays a crucial role in maintaining situational awareness, especially during high workload phases like takeoff, landing, or emergencies.
Shared duties
Despite the hierarchy, modern cockpits operate under Crew Resource Management (CRM) principles, which encourage open communication and shared responsibility. Some tasks are performed together or alternated between sectors:
Briefings
Checklist execution
Programming the FMS
Cross-checking altitudes and clearances
Verifying navigation and fuel planning
In a well-functioning cockpit, both pilots challenge and support each other, making the flight safer and smoother.
During emergencies
While the captain leads decision-making, the FO is critical in running checklists, communicating with ATC, and flying the aircraft if needed. The division of tasks becomes sharper, with one pilot handling the aircraft and the other handling systems and communication.
Example:
Captain: Focuses on flying and making the key decisions
First Officer: Handles abnormal checklists and talks to ATC
This structure prevents overload and ensures that no detail is missed under pressure.
The captain and copilot are not just two pilots sharing a cockpit — they’re a team with complementary roles. When each one understands their responsibilities and supports the other, the result is a safe, efficient, and professional operation.
Because in aviation, trust and coordination between both seats isn’t optional — it’s essential.
