Understanding what a First Officer does, how the role differs from a Captain and how it fits into a pilot’s career path is essential knowledge for aspiring airline pilots.

Captain vs. First Officer: What’s the Difference?

The Captain serves as the Pilot-in-Command (PIC) and has final authority over all operational decisions involving the aircraft. The First Officer, meanwhile, acts as the Captain’s primary support, sharing flying duties and playing an essential role in safety, communication, and decision-making. 

Most First Officers hold an Airline Transport Pilot (ATP) Certificate or a Restricted ATP (R-ATP), depending on their background and total flight time. Captains, by contrast, hold a full ATP and typically have greater experience and seniority. 

This structured progression helps maintain strong mentorship in the flight deck and promotes consistency, professionalism, and safety for passengers.

What Does a First Officer Do?

The First Officer is far more than just a co-pilot. They actively participate in every phase of flight, from preflight planning to landing, ensuring operations run smoothly and safely.

Preflight Responsibilities

Before the aircraft ever leaves the gate, the First Officer plays a major role in flight preparation. These duties include:

• Conducting detailed safety and system checks.
• Verifying that aircraft instruments and equipment function properly. 
• Reviewing the flight plan for accuracy and feasibility.

During flight planning, the First Officer evaluates key factors such as:

• Weather conditions along the route.
• Runway lengths at departure and destination airports. 
• Fuel requirements and reserves. 
• Potential air traffic delays.
• Alternate airports in case the original plan changes.

In-Flight Duties and Monitoring

The First Officer continuously monitors aircraft systems to detect abnormalities early. They also handle ongoing communication with air traffic control (ATC), providing updates on position, altitude, routing, and estimated arrival times. This constant monitoring adds redundancy to the flight deck, a core principle of airline safety. 

Flying the Aircraft: A Shared Control

First Officers actively fly the airplane, not just observe. On shorter domestic flights, Captains and First Officers typically alternate flying duties between flights. On long-haul or international flights, the First Officer may take control for extended periods, allowing the Captain to rest. If the Captain becomes incapacitated for any reason, the First Officer assumes control and safely operates the aircraft. 

Decision-Making in the Flight Deck

Airline flying rarely goes exactly as planned. One can almost always expect some change, regardless of whether it is weather-related, instructions provided by ATC, or onboard alerts. They all can require quick, informed decisions. 

When these situations arise, the First Officer works closely with the Captain to evaluate options such as:

• Changing course or altitude.
• Executing avoidance maneuvers. 
• Selecting the safest approach or landing technique. 
  
  

The First Officer provides input, analysis, and recommendations, always prioritizing safety. While the Captain makes the final decision, effective collaboration between both pilots is essential.

How Long Does a Pilot Remain a First Officer?

There is no fixed timeline for upgrading to Captain. Professional advancement for pilots depends on several factors, including:

Airline Policies

Some airlines require pilots to serve as First Officers for a set number of years before becoming eligible for an upgrade.

Experience and Competency

Time alone does not guarantee advancement. Pilots must demonstrate strong technical skills, leadership ability, sound judgment, and calm decision-making under pressure.

Availability of Captain Positions

Even qualified pilots must wait for open Captain positions, which depend on airline growth, retirements, and staffing needs. Most airline pilots eventually progress from First Officer to Captain, but continued learning and skill development remain essential throughout their careers. 

Preparing for the First Officer Role

The journey to becoming an airline Captain begins with mastering the role of First Officer. A stronger foundation in aeronautical knowledge, systems understanding, regulations, and real-world decision-making is critical.

MzeroA Online Ground School is proud to be the go-to resource trusted by pilots worldwide. Let’s explore the professional advancement opportunities available to today’s pilots.

Pilot Career Progression

As a pilot’s career develops, training and certifications become key milestones toward professional advancement. The most common pathway for U.S. pilots follows this sequence: Private Pilot Certificate → Instrument Rating → Commercial Pilot License → Instructor Ratings (with additional certificates and ratings that may follow) → Airline Transport Pilot License (ATP). 

Each step builds the foundation for new opportunities, advancing skill, knowledge, and experience. 

Private Pilot Certificate

Obtaining a Private Pilot Certificate  is the first step toward a professional aviation career. With this certificate, pilots can fly at night, operate in controlled airspace, and enjoy personal flights in the aircraft category they’re certified for, typically single-engine airplanes.

However, private pilots cannot fly for hire or compensation. This first certification is the gateway to experience, confidence, and higher certifications.

The training requirements to obtain a PPL are:

• At least 35 hours of flight time under a Part 141 program, or 40 hours under Part 61 training.
• 20 hours of instruction with a certified flight instructor
• Completion of a FAA Knowledge Exam
• Practical test with an FAA examiner 
  
  

Think of this certification as the foundation of your aviation education. The stage where future professional pilots first build their flight experience and decision-making skills. 

Flight Instructor Certification

Becoming a Certified Flight Instructor (CFI) is one of the most strategic moves in a pilot’s career. 

It isn’t just a career milestone; it’s a strategic financial decision. Instructors can gain the requisite 1,500 flight hours for an Airline Transport Pilot Certificate (ATP) more economically, as they earn while instructing, thereby bypassing the significant costs that come with accumulating flight hours independently. 

Airline Transport Pilot (ATP)

The Airline Transport Pilot (ATP) Certificate is the highest level certification a pilot can obtain. It’s required to serve as either Pilot in Command (Captain) or Second in Command (First Office) in FAR Part 121 operations and for certain FAR Part 135 operations. There are two types of ATP certifications:

Standard ATP License (ATP)

• Minimum Age Requirement: 23-years-old 
• Required Flight Time: 1,500 hours

Restricted ATP License (R-ATP)

This is an option for certain qualified individuals who may be military pilots and/or graduates of approved aviation programs, allowing them to obtain their ATP Certification with fewer than the standard 1500 hours. A R-ATP permits pilots to serve as a First Office in Part 121 airline operations until they meet the full ATP requirements. 

• Minimum Age Requirement: 21-years-old 
• Military pilots: 750 hours
• Graduates of four-year aviation universities: 1,000 hours
• Graduates of two-year aviation colleges: 1,250 hours
• Only pilots who have graduated from an FAA-approved university aviation program and completed their flight training with their Part 141 School are eligible. 
  
  

Pursuing this certification through specialized university programs or military service can provide an efficient path to meeting airline hiring prerequisites. 

Exploring Specialized and Alternative Pilot Careers

Not every pilot aspires to the traditional airline route, and that’s one of the most exciting aspects of aviation. Many choose to specialize in careers that combine technical expertise with adventure, service, or innovation. 

Cargo Transport

Cargo pilots play a crucial role in global business, transporting freight across borders and time zones. Depending on the operation, these flights may fall under FAR Part 121 (scheduled cargo) or FAR Part 135 (on-demand and commuter operations). While ATP certification is required for Part 121 operations, smaller Part 135 carriers may not require it. Cargo pilots often enjoy varied schedules and unique routes that keep every flight dynamic.

Corporate Pilot

Corporate pilots fly private jets and business aircraft for organizations or high-profile clients. This career demands professionalism, flexibility, and refined communication skills. Most corporate employers prefer at least 1,500 flight hours, a valid first or second-class medical certificate, and a Commercial Pilot License. 

Regional Airline Pilots

Many pilots begin their airline careers at regional carriers, operating mid-sized aircraft such as the ERJ 175 or CRJ 200. Regional airlines offer valuable multi-crew experience, turbine time, and exposure to airline operations, making them an ideal stepping stone to major carriers.

Specialized Aviation Roles

For those drawn to unique missions, aviation offers numerous specialized pathways:

• MedEvac pilots supporting life-saving medical transport.
• Aerial survey or mapping pilots.
• Tour or sightseeing pilots showcasing destinations.
• Aerial photography and cinematography professionals

Each of these roles provide the chance to merge passion with purpose, proving that aviation offers far more than a single career trajectory.
