A First Officer (FO) is the co pilot on an aircraft sitting beside the Captain and acting as the second in command.
From takeoff to landing a First Officer helps with communication and navigation. They talk with air traffic control (ATC) share flight plan details monitor radios update position and altitude and follow ATC instructions all vital for safe aircraft movement.
They also assist in planning the flight route checking weather fuel and aircraft systems before departure. During the flight, they monitor instruments navigation aids and ensure the plane stays on the correct path.
Modern air travel depends on two-pilot crews rather than larger crews with separate navigators or radio-operators. This makes the FO crucial to manage navigation and communication tasks.
Having two qualified pilots reduces workload on the Captain and allows shared responsibility the FO may be the "pilot flying" while the Captain monitors or vice versa but both remain alert to communication and navigation requirements.
In emergency situations if the Captain becomes unable to fly the First Officer must be ready to take full control. Their familiarity with navigation and communication ensures continuity and safety.
So, Who Is a First Officer and why do they handle communication and navigation Because modern cockpits operate on teamwork: FO supports the Captain by managing radios flight plans navigation instruments and aircraft systems. Their role ensures safety accuracy and smooth operation throughout the flight.
