Most people who want to fly have a general sense of where they’re headed: They want to be a pilot. What they’re less clear on is what the path looks like. How many certificates are there? What order do they come in? What does each one allow you to do?
The FAA’s pilot certification system is progressive by design. Each certificate or rating builds on the last, and each one expands your privileges and raises the standard you’re held to. The path isn’t identical for every pilot, but the building blocks are the same. Understanding the full picture before you start — or early in the process — helps you make better decisions about training, timing, and where you’re ultimately trying to go.
Here’s the full picture.
Student Pilot Certificate
The student pilot certificate is where every pilot’s logbook starts. It’s the FAA’s recognition that you’re actively training toward a pilot certificate, and it’s a prerequisite for solo flight — you cannot fly an aircraft alone without it.
Getting it is straightforward. You can apply for a student pilot certificate before you’re eligible to solo, but you must be at least 16 years old to solo a powered aircraft and be able to read, write, speak, and understand English. Most student pilots pursuing powered aircraft training will also need an FAA medical certificate before solo flight. The application is submitted through IACRA, the FAA’s Integrated Airman Certification and Rating Application system, and the certificate itself is issued by a FAA Aviation Medical Examiner.
What the student pilot certificate allows you to do is train toward a pilot certificate and, with the required endorsements from a certificated flight instructor, conduct solo flights. It does not allow you to carry passengers, fly for compensation, or operate outside the specific limitations your instructor endorses you for. Every solo flight you make as a student requires an active endorsement from your CFI. The certificate itself doesn’t expire, but the solo endorsements within it do, typically every 90 days.
Think of the student certificate as your learner’s permit. It’s permission to practice, not permission to operate independently.
Private Pilot Certificate (PPL)
The private pilot certificate is the foundational certificate of general aviation. It’s the first certificate that gives you meaningful operational freedom — the ability to fly as a pilot in command, carry passengers, and operate across a wide range of airspace and typical day-to-day flying conditions without an instructor in the seat next to you.
To earn it, you must be at least 17 years old, hold at least a third-class FAA medical certificate, log a minimum of 40 flight hours (though the national average runs considerably higher, typically around 60 to 70 hours), pass a written knowledge test, and complete a practical exam — the checkride — with an FAA Designated Pilot Examiner.
The 40-hour minimum includes specific requirements: at least 20 hours of flight training with an instructor, 10 hours of solo flight time, and within those totals, mandated cross-country, night, and instrument training hours. The knowledge test covers regulations, weather, navigation, aircraft systems, and aerodynamics. The checkride evaluates both your oral knowledge and your actual flying against the standards defined in the Private Pilot Airman Certification Standards.
The private pilot certificate allows you to fly for personal and recreational purposes and carry passengers, but not for compensation or hire. There are limited provisions that allow pilots and passengers to share certain operating expenses, but the moment money changes hands in a way that compensates you specifically for flying, you’ve stepped outside the privileges of the private certificate.
For most pilots, the PPL is the certificate that makes flying feel real. It’s also the foundation every subsequent certificate and rating is built on.
Instrument Rating
The instrument rating is not a separate certificate as it’s an add-on to your private or commercial pilot certificate, but it belongs in this conversation because it fundamentally changes what kind of pilot you are.
Without an instrument rating, your operations are generally limited to VFR conditions. You fly when and where the weather allows, and when it doesn’t, you stay on the ground or divert. That’s a significant operational limitation, and more importantly, it’s a safety limitation. A large percentage of fatal general aviation accidents involve VFR pilots who inadvertently enter instrument meteorological conditions (e.g., clouds, low visibility) and lose control of the aircraft because they weren’t trained for it.
The instrument rating trains you to safely control and navigate the aircraft primarily by reference to instruments, even when outside visual references are limited or unavailable. It teaches you to navigate via airways, fly published instrument approach procedures, and operate in the ATC system at a level that VFR pilots rarely reach. The FAA requires a minimum of 50 hours of cross-country flight time as pilot in command and 40 hours of actual or simulated instrument time, along with a written test and a checkride.
In practical terms, the instrument rating makes you a more capable, safer, and more versatile pilot. For anyone pursuing a commercial certificate or flying professionally, it isn’t optional — it’s a prerequisite for most professional flying opportunities.
Commercial Pilot Certificate (CPL)
The commercial pilot certificate is what separates flying as a hobby from flying as a profession. It authorizes you to act as pilot in command of an aircraft for compensation or hire — to get paid to fly.
The eligibility requirements step up accordingly. You must be at least 18 years old, meet FAA medical eligibility requirements, and accumulate a minimum of 250 total flight hours, with specific requirements within that total: 100 hours in powered aircraft, 100 hours as pilot in command, 50 hours of cross-country flight, and 10 hours of instrument training, among others. The written exam covers more advanced aeronautical knowledge than the private, and the checkride evaluates a higher standard of precision and professionalism in your flying.
The instrument rating, while technically not a prerequisite for the commercial certificate itself, is a practical necessity. A commercial certificate without an instrument rating comes with a restriction limiting you to VFR-only operations, which eliminates most commercial flying opportunities before you even start.
What the commercial certificate allows depends on how it’s used. Banner towing, aerial photography, pipeline patrol, agricultural operations, and charter flying all require at a minimum a commercial certificate. Scheduled airline operations require something more — but that comes later.
The commercial certificate is also issued when the standards change in a meaningful way. The maneuvers are more demanding, the precision requirements are tighter, and the expectation is that you fly the aircraft deliberately and professionally. That shift in standard is intentional.
Multi-Engine Rating
Most of the flight training that leads to the private and commercial certificates happens in single-engine aircraft. The multi-engine rating authorizes you to act as pilot in command of multi-engine aircraft — a category that includes a wide range of aircraft used throughout professional aviation.
Unlike the certificates above, the multi-engine rating has no FAA-mandated minimum hour requirement. There’s no written test, either. Instead, the training culminates in a checkride, and the preparation for that checkride is the training itself. Many pilots complete their initial multi-engine rating in somewhere between five and fifteen hours of training, depending on their existing proficiency level and how quickly they adapt to multi-engine aerodynamics.
That adaptation is where the complexity lives. Flying a light twin isn’t dramatically different from flying a single-engine aircraft until you lose an engine. Engine-out aerodynamics, single-engine performance limitations, critical engine concepts, and Vmc — minimum control speed — are at the core of multi-engine training and require genuine understanding, not just proficiency with the maneuvers.
For pilots pursuing a career in aviation, the multi-engine rating is a required step. Most professional flying opportunities (regional airlines, charter operations, and corporate aviation) involve multi-engine aircraft. Building multi-engine time becomes an important part of progressing toward airline and ATP-level flying.
Certificated Flight Instructor (CFI)
The flight instructor certificate is the aviation industry’s most common path to building flight hours toward ATP minimums, and it’s also one of the most demanding certificates to earn. Teaching someone to fly requires a different level of mastery than flying well yourself; you have to understand the material deeply enough to explain it clearly, demonstrate it precisely, and correct someone else’s errors from the right seat while maintaining safe aircraft control.
To become a CFI, you must hold a commercial pilot certificate, pass a written test (two, actually — one on fundamentals of instruction and one on flight instructor topics), and complete a checkride that’s widely regarded as one of the most rigorous in general aviation. The examiner can ask you about essentially anything, and the expectation is that you can teach it, not just answer a question about it.
The flight instructor certificate authorizes you to provide flight instruction and endorse students for solo flight, cross-country operations, and knowledge tests. Additional ratings, including the CFII for instrument instruction and the MEI for multi-engine instruction, require separate endorsements and checkrides.
Beyond the hour-building aspect, instructing makes you a better pilot. Explaining why an aircraft behaves the way it does, catching errors before they develop, and operating safely in training environments where the unexpected is routine — all of it sharpens skills that stay with you throughout your career.
Airline Transport Pilot (ATP)
The ATP certificate is the highest pilot certificate the FAA issues, and it’s the legal requirement for serving as pilot in command of a scheduled air carrier aircraft operating under Part 121 — the rules governing commercial airlines.
Eligibility requirements reflect the level of responsibility the certificate carries. You must be at least 23 years old (21 for a restricted ATP, which carries operational limitations) and accumulate a minimum of 1,500 total flight hours. Within that total, the requirements include 500 hours of cross-country time, 100 hours of night flight, and 75 hours of actual or simulated instrument time, among others. Graduates of an FAA-approved aviation program at an accredited institution may qualify for a restricted ATP with reduced flight-hour requirements under specific provisions. Most airline operations also require a first-class medical certificate.
Before the checkride, candidates must complete an ATP Certification Training Program, which is an FAA-approved ground and simulation-based course that covers advanced aerodynamics, aircraft systems, crew resource management, and scenario-based training that goes significantly beyond what most pilots encounter earlier in their training.
For many airline-track pilots, the ATP checkride is conducted in a full-flight simulator and evaluated against the ATP Airman Certification Standards — the most demanding set of standards in civilian pilot training.
Holding an ATP doesn’t automatically mean you’re flying for an airline. The certificate is also a mark of overall aeronautical proficiency and opens doors across professional aviation — charter, corporate, cargo, and beyond. But for the pilots whose goal from the beginning has been the left seat of a commercial airliner, the ATP is what that path has been building toward from the day they took their first lesson.
The Path Forward
Every certificate on this list represents a defined level of knowledge, skill, and aeronautical decision-making. None of them are handed out. They’re earned through logged hours, knowledge tests, and checkrides that hold you to a published standard.
