Pilot certification in the United States

Pilot certification in the United States is typically required for an individual to act as a pilot-in-command of an aircraft. It is regulated by the Federal Aviation Administration (FAA), a branch of the U.S. Department of Transportation (USDOT). A pilot may be certified under 14 Code of Federal Regulations (CFR) Part 61 or 14 CFR Part 141 (if a student at an approved part 141 school). Pilots may also be certified under 14 CFR Part 107 for commercial drone operations.
An FAA-issued "pilot certificate" is evidence that an individual is duly authorized to exercise piloting privileges. The pilot certificate is one of several kinds of "airman certificates" issued by the FAA.
General structure of certification.
A pilot is certificated to fly aircraft at one or more named "privilege levels" and, at each privilege level, rated to fly aircraft of specific "categories". Privilege levels of pilot certificates are, in order of increasing privilege:
Pilots can be rated in these aircraft categories:
Most aircraft categories are further broken down into "classes". If a category is so divided, a pilot must hold a class rating to operate an aircraft in that class:
A student pilot certificate does not list category or class ratings but is instead endorsed by a flight instructor to confer privileges in specific makes and models of aircraft.
A "type rating" is required in a specific make and model of aircraft if the aircraft weighs more than at takeoff or is powered by one or more turbojet engines. The Boeing 747, Beechcraft Super King Air 350, and the Hawker Hunter are examples of aircraft that require type ratings.
To legally operate under instrument flight rules (IFR), a pilot can separately add an instrument rating to a private or commercial certificate. An airline transport pilot implicitly holds an instrument rating, so the instrument rating does not appear on an ATP certificate. The FAA issues instrument ratings separately for airplane and powered lift categories and the helicopter class (INSTA and INSTH). Glider and airship pilots may also operate under Instrument Flight Rules under certain circumstances. An individual may hold only one pilot certificate at one time; that certificate may authorize multiple privilege levels distinguished by aircraft category, class or type. For example, an Airline Transport Pilot certificate holder may be permitted to exercise ATP privileges when flying multi-engine land airplanes, but only Commercial Pilot privileges when flying single-engine land airplanes and gliders. Similarly a Commercial Pilot holder with a glider rating may have only Private Pilot privileges for single-engine land airplanes.
The FAA may impose "limitations" on a pilot certificate if, during training or the practical test, the pilot does not demonstrate all skills necessary to exercise all privileges of a privilege level, category, class or type rating. For example, a holder of a DC-3 type rating who does not demonstrate instrument flying skills during the practical test would be assigned a limitation reading, "DC-3 (VFR Only)".
To obtain a certificate or add a rating, a pilot usually has to undergo a course of training with a Certificated Flight Instructor (CFI) under 14CFR61 or enroll at an approved course at a 14CFR141 approved flight school. The applicant must accumulate and log specific aeronautical experience, and pass a three-part examination: a "knowledge test" (a computerized multiple-choice test, typically called the "written test"), an "oral" test, and a "practical" test carried out by either an FAA inspector or a Designated Pilot Examiner.
Another form of authorization is a logbook "endorsement" from a flight instructor that establishes that the certificate holder has received training in specific skill areas that do not warrant a full test, such as the ability to fly a tailwheel-equipped, high-performance, complex, or pressurized airplane.
Pilot certificates do not expire, although they may be suspended or revoked by the FAA. However, a pilot must maintain "currency" — recent flight experience that is relevant to the flight being undertaken. To remain current, every pilot has to undergo a flight review with an instructor every 24 calendar months unless she or he gains a new pilot certificate or rating in that time or satisfies the flight review requirement using an alternate approved means. For most types of certificate, she or he must also undergo a medical examination at intervals ranging from six months to five years, depending on the pilot's age and desired flight privileges. Other currency requirements apply to the carriage of passengers or to flight under instrument flight rules (IFR).
A medical certificate is not necessary to fly a glider, balloon, or light-sport Aircraft. An ultralight aircraft may be piloted without a pilot certificate or a medical certificate.
In addition to pilot certificates, the FAA issues separate airman certificates for Flight Engineers, Flight Instructors, Ground Instructors, Aircraft Dispatchers, Mechanics, Repairmen, Parachute Riggers, Control Tower Operators, Flight Navigators, and Flight Attendants.
Pilot training.
Most pilots in the U.S. undergo flight training as private individuals with a flight instructor, who may be employed by a flight school. Those who have decided on aviation as a career often begin with an undergraduate aviation-based education. Some pilots are trained in the military and are issued with civilian certificates based on their military record. Others are trained directly by airlines. The pilot may choose to be trained under Part 61 or Part 141 of the FARs. Part 141 requires that a certificated flight school provide an approved, structured course of training, which includes a specified number of hours of ground training (for example, 35 hours for Private Pilot in an airplane). Part 61 sets out a list of knowledge and experience requirements, and is more suitable for students who cannot commit to a structured plan, or for training from freelance instructors. Under Part 61 pilot training, individuals can become a private pilot in about three months and a commercial pilot in as quick as seven months.
Knowledge tests.
Most pilot certificates and ratings require the applicant to pass a knowledge test, also called the written test. The knowledge test results are valid for a period of 2 years, and are usually a prerequisite for practical tests. Resources available to prepare for the knowledge test may be obtained from pilot supply stores or vendors. The exceptions where a knowledge exam is not required for a practical test are for some add-on ratings after the initial license, such as a powered aircraft pilot adding another category rating at the same license level.
To take knowledge tests for all pilot certificates and ratings, the applicant must have a sign-off from a ground or flight instructor. These are usually given by an instructor who has taught a ground school course, provided ground instruction or reviewed the applicant's self-study preparations. Certain circumstances don't require sign-offs for some flight instructor or airline transport pilot knowledge tests.
Practical tests.
All pilots certificates and ratings require a practical test, usually called a "check ride". For each practical test, the FAA publishes an Airman Certification Standards (ACS) document (formerly Practical Test Standards (PTS)) that they expect the applicant to be familiar with, the flight instructor to reference, and the examiner to use to conduct the exam. A practical test is administered by an FAA Inspector or an FAA Designated Pilot Examiner. The check-ride is divided into two parts: the oral exam followed by a flight test in the aircraft. Upon successful completion of the practical test, the examiner issues a temporary airman certificate with the new license or rating. To take practical tests for all pilot certificates and ratings (except airline transport pilot), the applicant must have proper logbook endorsements from their flight instructor, and meet basic eligibility requirements required for the ratings desired.
Becoming a professional pilot.
In aviation, a pilot's level of income and experience are closely related. There are multiple ways to gain the experience required for hire by a scheduled air carrier. Air carriers generally require that the pilots they hire have hours of experience far in excess of the legal minimum. Effective August 1, 2013, all airline pilots must have an Airline Transport Pilot Certificate (ATP) or an Airline Transport Pilot Certificate with restricted Privileges (ATP-r). An ATP allows a pilot to act as the captain or first officer of an airline flight and requires 1,500 hours of total flight time as well as other requirements (i.e. 25 hours of night, 23 years old), see 14CFR61.159. An ATP-r certificate allows a pilot to act as a first officer in a two-pilot crew if they do not meet certain requirements. For example, the total flight time requirement is reduced to as little as 750 hours and the age requirement is reduced to 21. see 14CFR61.160.
Experience is often gained using these methods:
Pilot certificates.
The FAA offers a progression of pilot certificates or licenses. Each license has varying experience and knowledge requirements and has varying privileges and limitations.
Student pilot.
A student pilot certificate is obtained through the FAA's Integrated Airman Certification and Rating Application (IACRA) system. The student pilot certificate is only required when exercising solo flight privileges. Student pilots must also possess a medical certificate when conducting flights requiring medical certification. As of April 1, 2016 student pilot certificates do not expire. Once a student has accrued sufficient training and experience, a CFI can "endorse" the student's logbook to authorize limited solo flight in a specific type (make and model) of aircraft. Additional endorsements must be logged for specific airports where a student operates solo.
There is no minimum aeronautical knowledge or experience requirement for the issuance of a student pilot certificate. There are, however, minimum aeronautical knowledge and experience requirements for student pilots to solo, including:
Solo requirements:
Limitations while flying solo:
Sport pilot.
The sport pilot certificate was created in September 2004. The intent of the new rule was to lower the barriers of entry into aviation and make flying more affordable and accessible.
The new rule also created the Light Sport Aircraft (LSA) category of aircraft, which are smaller, lower-powered aircraft. The sport pilot certificate offers limited privileges mainly for recreational use. It is the only powered aircraft certificate that does not require a medical certificate; a valid vehicle driver's license can be used as proof of medical competence "provided" the prospective pilot was not rejected for their last Airman Medical Certificate.
Before a trainee can start the solo phase of flight training, a Student Sport Pilot Certificate must be issued by the Federal Aviation Administration (FAA). These may be obtained from an FAA Flight Standards District Office or FAA Designated Pilot Examiner.
To qualify for the sport pilot certificate, an applicant must:
The above requirements are for heavier-than-air powered aircraft (airplanes). The requirements for gliders, balloons, gyroplanes, and dirigibles vary slightly.
Sport pilots are only eligible to fly aircraft that are either certificated specifically as light-sport aircraft (LSA) or were certificated prior to the LSA regulations and are within the maximum weight and performance limitations of light-sport aircraft.
The restrictions placed on a Pilot exercising the privileges of a Sport pilot certificate are:
The Sport pilot certificate is also ineligible for additional ratings (such as an Instrument rating), although time in light-sport aircraft can be used towards the experience requirement of other ratings on higher certificate types.
Recreational pilot.
The recreational pilot certificate requires less training and offers fewer privileges than the private pilot certificate. It was originally created for flying small single-engine planes for personal enjoyment; the newer Sport Pilot certificate overlaps this need and is easier to get, but the recreational certificate allows access to larger single-engine aircraft, and instructor endorsements are available to recreational pilots that are not applicable to sport pilots, such as flying at night or cross-country.
Eligibility requirements:
Limitations and restrictions (without additional endorsement):
Most of the above limitations, except the one-passenger, four-seat and single-engine restrictions, can be relaxed or lifted individually through instructor endorsement. These endorsements are obtained by participating in a prescribed course of ground and/or flight instruction given by an FAA-certificated instructor, including a minimum number of instructor-led flight in a plane or situation normally requiring the endorsement. Common types of endorsement for recreational pilots can allow:
A recreational pilot will typically only get a few of these, to allow operation of an aircraft in a few exceptional situations applicable to their locale (the Class B/C/D endorsement, for instance, is practically required for pilots living in major cities). Pilots requiring a large subset of these endorsements are typically better served by obtaining their private pilot certification.
Private pilot.
The private pilot certificate allows command of any aircraft (subject to appropriate ratings) for any non-commercial purpose, and gives almost unlimited authority to fly under visual flight rules (VFR). Passengers may be carried and flight in furtherance of a business is permitted; however, a private pilot may not be compensated in any way for services as a pilot, although passengers can pay a "pro rata" share of flight expenses, such as fuel or rental costs. Private pilots may also operate charity flights, subject to certain restrictions, and may participate in similar activities, such as Angel Flight, Civil Air Patrol and many others. Besides the student pilot certificate, the private pilot certificate is the most commonly issued pilot certificate in the United States.
The requirements to obtain a private pilot certificate for "airplane, single-engine, land", or ASEL, (which is the most common certificate) are:
Commercial pilot.
A certificated commercial pilot may act as pilot-in-command of an aircraft for compensation or hire, as well as carry persons or property for compensation or hire. Training for the certificate focuses on a better understanding of aircraft systems and a higher standard of airmanship. The commercial certificate itself does not allow a pilot to fly in instrument meteorological conditions. For aircraft categories where an instrument rating is available, commercial pilots without an instrument rating are restricted to daytime flight within when carrying passengers for hire.
A commercial airplane pilot must be able to operate a complex airplane, as a specific number of hours of complex (or turbine-powered) aircraft time are among the prerequisites.
The requirements are:
By itself, this certificate does not permit the pilot to set up an operation that carries members of the public for hire; such operations are governed by other regulations. Otherwise, a commercial pilot can be paid for certain types of operation, such as banner towing, agricultural applications, and photography, and can be paid for instructing if she or he holds a flight instructor certificate (In the case of lighter-than-air, only a commercial pilot certificate is required to teach for that category). To fly for hire, the pilot must hold a second class medical certificate, which is valid for 12 calendar months if the pilot is 40 years or older; if the pilot is less than 40 years old the certificate is valid for 24 calendar months.
Often, the commercial certificate reduces the pilot's insurance premiums, as it is evidence of training to a higher safety standard.
Airline transport pilot.
An airline transport pilot (commonly called an "ATP") is tested to the highest level of piloting ability. The certificate is a prerequisite for acting as a flight crew-member in scheduled airline operations.
The minimum pilot experience is 1,500 hours of flight time (1200 for Helicopters), 500 hours of cross-country flight time, 100 hours of night flight time, and 75 hours instrument operations time (simulated or actual). Other requirements include being 23 years of age, an instrument rating, being able to read, write, speak, and understand the English language, a rigorous written examination, and being of good moral character.
An Airline Transport Pilot – restricted (ATP-r) is also available for pilots that do not meet the more rigorous requirements of an ATP. The only hour requirement for the ATP-r is 1,500 total and 200 cross country. The "total time" requirement is reduced to 750 hours for former military pilots, 1,000 hours for graduates of university bachelor's degree programs, or 1,250 for graduates of university associate degree programs. The holder of an ATP-r is limited to only serving as the first officer in a two-pilot operation. Upon obtaining the requisite age and aeronautical experience, the pilot is issued an unrestricted ATP without further examination. see 14CFR61.160 (requirements) and 14CFR61.167 (privileges and limitations)
Remote pilot.
UAVs weighting between more than 0.55 lbs and less than 55 lbs or used in a commercial nature is subject to Part 107 regulations. Exemptions for Part 107 are granted on a case by case basis by the FAA subject to risk mitigation. UAV weighting 55 lbs or more are subject to Part 333 regulations.
Eligibility requirements:<br>
(Non Part 61 certificate holders) 
Restrictions 
It is possible to mix the license levels on one certificate. For example, a private pilot with both glider and airplane ratings could earn a commercial license for gliders. The new license would then list the airplane ratings as having only "private privileges."
Number of active pilots.
As of the end of 2019, in the US, there were an estimated 664,565 active certificated pilots. This number has been declining gradually over the past several decades, down from a high of over 827,000 pilots in 1980. There were 702,659 in 1990 and 625,581 in 2000. The numbers include:
These numbers are based on the highest certifications held by individual pilots.
The numbers also include: 
An active pilot is defined as one who holds both a pilot certificate and a valid medical certificate, for certifications that require a medical certificate.
Other certificates and ratings.
United States military pilots are issued an Aviator Badge upon completion of flight training and issuance of a pilot's certificate. Badges for crew or ground positions are also issued to qualified applicants.
Unmanned Aircraft System (Drone) pilots are required to obtain a remote pilot airman certificate with a small UAS rating when operating commercially.
Medical certification and requirements.
All certificated pilots, with the exception of those with a sport or Recreational pilot certificate (or when in command of balloons or gliders, including power assisted gliders), are required to maintain a medical certification commensurate with the privileges they intend to exercise as pilot-in-command of an aircraft.
For sport pilot certificate applicants or holders, regulations state that a medical is required if the applicant/pilot does not hold a valid United States drivers license.
To obtain a medical certification, pilots are required to undergo a medical examination from an Aviation Medical Examiner, or AME. The Aviation Medical Examiner performs an examination based upon the class of certification desired.
Medical certifications are divided into three classes:
Third class.
Third class certifications require the least involved examinations of all medical certifications. They are required for those intending to be pilot-in-command of an aircraft under the Private or Recreational pilot certificates or while exercising solo privileges as a student pilot.
To qualify for a third class medical certificate, pilots must meet the following requirements:
For pilots under 40 years of age, third class medical certificates expire on the last day of the month they were issued, five years from the date of issue. The FAA changed this rule from three to five years on July 24, 2008. For all others, they expire on the last day of the month they were issued, two years from the date of issue.
In December 2015, the U.S. Senate passed a bill sponsored by Montana Senator Steve Daines, S. 571- Pilot's Bill of Rights 2 (PBOR 2). If signed into law, the bill would expand the third class medical exemption for recreational pilots by reforming the FAA's medical certification process to include more qualified, trained pilots.
Second class.
A second class medical is required for those intending to exercise the privileges of the commercial pilot certificate. It is possible to obtain a commercial pilot certificate while holding a third class medical, but with the exception of flight instruction, the licensee cannot exercise privileges beyond that of a private pilot.
To qualify for a second class medical certificate, pilots must meet the requirements for the third class certificate plus:
Second class certificates are valid until the last day of the month, twelve months after they were issued. The certificate holder may then only exercise the privileges of a third class medical certificate.
First class.
First class certificates are required for those intending to be pilot-in-command in an air carrier operation requiring an Airline Transport Pilot (ATP) certificate. Other operations, including those under Part 91, may require a first class medical for insurance purposes, although it is not a federal requirement in such cases.
To qualify for the first class medical certificate, pilots must meet the requirements for the third and second class certificates plus:
For pilots under 40 years of age, first class medical certificates expire on the last day of the month they were issued, one year from the date of issue. The FAA introduced this rule on July 24, 2008.
For all others, they are valid until the last day of the month, six months after they were issued. The certificate holder may then only exercise the privileges of a second class medical certificate until the last day of the month, twelve months after the certificate was issued, thereafter the privileges of a third class medical until the last day of the month, twenty four months after the medical was issued ( FAA $61.23 (d-1-iii) ).
Special issuance.
Pilots who do not meet the above requirements may be issued a medical certificate under a "special issuance." A special issuance is essentially a waiver for a disqualifying condition and are evaluated case-by-case depending on the class of certificate requested. Minor problems can be overcome by a special issuance from an Aviation Medical Examiner, while others require a special issuance from the FAA directly.
Restrictions.
Restrictions may be placed upon a medical certificate to mitigate any concern for safety. A common restriction for pilots who require glasses or contacts to meet the required visual acuity standards is that they "MUST WEAR CORRECTIVE LENSES." Color-blind pilots are typically issued a restriction reading, "NOT VALID FOR NIGHT FLIGHT OR BY COLOR SIGNAL CONTROL." This mitigates the concern that color-blind pilots may not be able to identify those colors required for the performance of safe airman duties by preventing situations that are considered potentially unsafe.
For color vision deficient pilots, in many cases these restrictions can be removed through use of an FAA approved alternative office based color vision test, which if passed, the applicant must continue to retake that same test (or any other passable tests) at every renewal. If the pilot applicant is unable to pass any of the office based tests, a real world operational test is available. This test consists of a ground-based chart reading and control tower signal light test for Third Class medical certification (This is called the Operational Color Vision Test or OCVT), and in addition to that, a specialized "Medical Flight Test" (MFT) is required for Second and First Class medical certification. The applicant performs an actual flight test with an FAA Aviation Safety Inspector (ASI) for the purpose of further demonstrating "the ability to perceive those colors necessary for the safe performance of airman duties", which is the color vision requirement as written in the FARs. Note that "Normal Color Vision" is not required, as a certain amount of color vision deficiency is considered safe and permitted. If the tests are passed, a "Letter of Evidence" (LOE) from the FAA is issued, which serves as evidence that the pilot meets the standards for Color Vision and the AME is permitted to issue the class of Medical Certificate indicated on the LOE (All classes if both the OCVT and MFT are passed) with no related restriction if all other medical requirements are met. This allows the pilot to receive a medical certificate with no restrictions related to color vision without the requirement of passing an office based color vision test at every subsequent renewal. Alternatively, If an applicant is unable to pass both the OCVT and MFT, the applicant will keep the restriction permanently and will not be allowed any more future attempts to remove it. Therefore, this method of restriction removal is seen as a high-risk high-reward option for aspiring pilots with color vision deficiency. 
Non-pilot certifications.
In addition to pilot licenses the FAA also issues other airmen certificates.
Pilots do not need FCC licenses to use the radio within the United States (pilot certificates double as FCC radio licenses); however, other countries may require that a pilot have an FCC Restricted Radiotelephone Operator Permit (RR), and the aircraft radio station be licensed.
