A modern airliner flight deck is designed for two trained pilots who work as a coordinated team. The captain sits in the left seat and has final authority for the safety of the flight, while the first officer sits in the right seat and is a fully qualified pilot. Each pilot has access to flight controls, instruments, communication equipment, and navigation displays.
This two-person system matters because it adds redundancy, shared workload, and continuous cross-checking during every phase of flight.
The crew also divides tasks into temporary operating roles called pilot flying and pilot monitoring. The pilot flying controls the flight path, either manually or through the autopilot, while the pilot monitoring handles radios, checklists, system monitoring, and verification of actions. These roles can be assigned to either the captain or the first officer and may change between flight legs.
Clear callouts, standard procedures, and mutual confirmation help prevent errors when conditions are busy or stressful.
Key Facts
- The captain is the pilot in command and has final legal authority for the flight.
- The first officer is a qualified pilot who shares flying duties, monitoring duties, and decision support.
- Pilot Flying, PF, manages the flight path, speed, altitude, and aircraft configuration.
- Pilot Monitoring, PM, handles radios, checklists, system checks, and cross-checks the PF.
- Distance = ground speed x time, so 450 knots for 2 hours gives 900 nautical miles.
- Fuel remaining = fuel at start - fuel used, a basic check both pilots monitor during flight.
Vocabulary
- Captain
- The captain is the pilot in command with final responsibility for the aircraft, crew, passengers, and safe operation of the flight.
- First Officer
- The first officer is the second pilot on the flight deck and is fully trained to operate the aircraft and assist the captain.
- Pilot Flying
- The pilot flying is the crew member currently responsible for controlling the aircraft flight path manually or through automation.
- Pilot Monitoring
- The pilot monitoring is the crew member who watches instruments, communicates on radios, runs checklists, and verifies actions.
- Cross-check
- A cross-check is the process of one pilot verifying information, settings, or actions made by the other pilot.
Common Mistakes to Avoid
- Thinking the captain always physically flies the airplane is wrong because either the captain or first officer can be assigned as pilot flying.
- Assuming the first officer is a trainee is wrong because a first officer is a qualified pilot with required licenses, ratings, and aircraft training.
- Ignoring the pilot monitoring role is wrong because monitoring, radio work, and checklist discipline are essential safety tasks, not passive duties.
- Changing an autopilot, radio, or navigation setting without confirmation is wrong because flight deck procedures rely on verbal callouts and cross-checks to catch errors.
Practice Questions
- 1 An aircraft flies at a ground speed of 420 knots for 1.5 hours. How many nautical miles does it travel?
- 2 A flight begins with 18,000 kg of fuel and burns 2,400 kg per hour for 3 hours. How much fuel remains?
- 3 During approach, the first officer is pilot flying and the captain is pilot monitoring. Explain two actions the captain should perform to support a safe landing.
