The pilot in command (PIC) of an aircraft is the person aboard an aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three-pilot aircrew, or "pilot" if there is only one certificated and qualified pilot at the controls of an aircraft. The PIC must be legally certificated (or otherwise authorized) to operate the aircraft for the specific flight and flight conditions, but need not be actually manipulating the controls at any given moment. The PIC is the person legally in charge of the aircraft and its flight safety and operation, and would normally be the primary person liable for an infraction of any flight rule.
The strict legal definition of PIC may vary slightly from country to country. The International Civil Aviation Organization (ICAO) definition is: "The pilot responsible for the operation and safety of the aircraft during flight time." [1]
In Annex 2, "Rules of the Air", under par. "2.3.1 Responsibility of pilot-in-command", ICAO declares: [1]
The pilot-in-command of an aircraft shall, whether manipulating the controls or not, be responsible for the operation of the aircraft in accordance with the rules of the air, except that the pilot-in-command may depart from these rules in circumstances that render such departure absolutely necessary in the interests of safety.
In Annex 2, par. "2.4 Authority of pilot-in-command of an aircraft", ICAO adds: [1]
The pilot-in-command of an aircraft shall have final authority as to the disposition of the aircraft while in command.
ICAO Annex 2, par. 2.3.1, specifically empowers the PIC to override any other regulation in an emergency, and to take the safest course of action at his/her sole discretion. This provision mirrors the authority given to the captains of ships at sea, with similar justifications. It essentially gives the PIC the final authority in any situation involving the safety of a flight, irrespective of any other law or regulation.
Logging flight time as a PIC is distinct from acting as the legal PIC of a flight. The PIC of a given flight may always log his or her flying time as such. Other crew members may or may not be authorized to log their time on that flight as PIC time, depending on the specific circumstances and the controlling jurisdiction. [2]
Time logged as "student pilot in command" (SPIC) can sometimes be partly used towards the hour requirements for the issue of a commercial pilot licence (CPL). In EASA states, SPIC time means "a student pilot acting as pilot-in-command on a flight with an instructor where the latter will only observe the student pilot and shall not influence or control the flight of the aircraft." It is logged in the pilot's logbook as PIC but must be countersigned by the flight instructor. [3] : 36 SPIC time may be partially used by the holder of a multi-crew pilot licence towards the issuance of a commercial pilot licence. [3] : 717
Time logged as "pilot-in-command under supervision" (PICUS) may be partly used towards the hour requirements for the issue of an airline transport pilot licence (ATPL). In EASA states, a pilot-in-command under supervision means "a co-pilot performing, under the supervision of the pilot-in-command, the duties and functions of a pilot-in-command." [3] : 19 PICUS time is logged as PIC as long as "the intervention of the PIC in the interest of safety was not required", but must be countersigned by the PIC. [3] : 31 [4] PICUS time is typically only logged when the co-pilot is acting as pilot flying.
In most countries one is required to obtain a glider pilot license (GPL) or certificate before acting as pilot of a glider. The requirements vary from country to country.
A private pilot licence (PPL) or private pilot certificate is a type of pilot licence that allows the holder to act as pilot in command of an aircraft privately. The basic licence requirements are determined by the International Civil Aviation Organization (ICAO), but implementation varies from country to country. According to ICAO, an applicant must be at least 17 years old, demonstrate appropriate knowledge and skill, and hold at least a Class 3 medical certificate. Different PPLs are available for different categories of aircraft, such as aeroplane, helicopter, airship, etc, and are not interchangeable, although experience from a PPL in one category may be credited towards the issue of another.
The airline transport pilot licence (ATPL), or in the United States of America, an airline transport pilot (ATP) certificate, is the highest level of aircraft pilot certificate.
A commercial pilot licence (CPL) is a type of pilot licence that permits the holder to act as a pilot of an aircraft and be paid for their work.
The Convention on International Civil Aviation, also known as the Chicago Convention, established the International Civil Aviation Organization (ICAO), a specialized agency of the United Nations charged with coordinating international air travel. The Convention establishes rules of airspace, aircraft registration and safety, security, and sustainability, and details the rights of the signatories in relation to air travel. The convention also contains provisions pertaining to taxation.
Pilot licensing or certification refers to permits for operating aircraft. Flight crew licences are issued by the civil aviation authority of each country, which must establish that the holder has met minimum knowledge and experience before issuing licences. The licence, along with the required class or type rating, allows a pilot to fly aircraft registered in the licence issuing state.
Pilot licensing in the United Kingdom is regulated by the Civil Aviation Authority (CAA).
In aviation, the first officer (FO), also called co-pilot, is a pilot in addition to the captain, who is the legal commander. In the event of incapacitation of the captain, the first officer will assume command of the aircraft.
A flight instructor is a person who teaches others to operate aircraft. Specific privileges granted to holders of a flight instructor qualification vary from country to country, but very generally, a flight instructor serves to enhance or evaluate the knowledge and skill level of an aviator in pursuit of a higher pilot's license, certificate or rating.
A flight dispatcher assists in planning flight paths, taking into account aircraft performance and loading, enroute winds, thunderstorm and turbulence forecasts, airspace restrictions, and airport conditions. Dispatchers also provide a flight following service and advise pilots if conditions change. They usually work in the operations center of the airline. In the United States and Canada, the flight dispatcher shares legal responsibility with the commander of the aircraft.
In aviation, airworthiness is the measure of an aircraft's suitability for safe flight. Initial airworthiness is demonstrated by a certificate of airworthiness issued by the civil aviation authority in the state in which the aircraft is registered, and continuing airworthiness is achieved by performing the required maintenance actions.
A type rating is an authorization entered on or associated with a pilot license and forming part thereof, stating the pilot's privileges or limitations pertaining to certain aircraft type. Such qualification requires additional training beyond the scope of the initial license and aircraft class training.
Cross-country flying is a type of distance flying which is performed in a powered aircraft on legs over a given distance and in operations between two points using navigational techniques; and an unpowered aircraft by using upcurrents to gain altitude for extended flying time. Cross country is distinct from purely aerial work in a small defined area requiring little navigation.
Medical certifications for aircraft pilots are specified by the International Civil Aviation Organization (ICAO). ICAO sets standards and recommended practices (SARPS), which are specified in Annex 1 to the Convention on International Civil Aviation.
General aviation (GA) has been defined as a civil aircraft operation other than a commercial air transport flight operating to a schedule. Although the International Civil Aviation Organization (ICAO) excludes any form of remunerated aviation from its definition, some commercial operations are often included within the scope of General Aviation (GA). General aviation refers to all flights other than military and scheduled airline flights, both private and commercial.
A civil aviation authority (CAA) is a national or supranational statutory authority that oversees the regulation of civil aviation, including the maintenance of an aircraft register.
The light aircraft pilot licence (LAPL) is a pilot license allowing the pilot to fly small aircraft. It is issued in EASA member states and the United Kingdom. Unlike most other licences, it is not covered by the ICAO framework and is usually not able to be used in other states or regulatory areas.
A pilot logbook is a record of a pilot's flying hours. It contains every flight a pilot has flown, including flight time, number of landings, and types of instrument approaches made. Pilots also log simulator time, as it counts towards training.
Flight time or block time is an aviation term referring to the total amount of time spent piloting aircraft, and serves as the primary measure of a pilot's experience. Flight time is defined by International Civil Aviation Organization (ICAO) as "The total time from the moment an aeroplane first moves for the purpose of taking off until the moment it finally comes to rest at the end of the flight", and thus includes time spent taxiing and performing pre-flight checks on the ground, provided the engine is running. It is colloquially referred to as "blocks to blocks" or "chocks to chocks" time. In commercial aviation, this means the time from pushing back at the departure gate to arriving at the destination gate.
Aviation in the European Union and the European Free Trade Association is regulated by the European Union Aviation Safety Agency (EASA). EASA specifies common standards for the licensing of aircraft pilots. EASA does not issue licences, rather licences are issued by member states. However, because the same standards are used, EASA licences are recognised by all member states.
