A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
Physics as they apply to aircraft. Including aerodynamics, flight dynamics, stability and control, aircraft hydraulic and electric systems, engine thermodynamics.
A runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft" (ICAO definition).
Flight planning is the process of preparing for a flight: planning a route to fly, identifying alternate destinations in case of diversion, calculating required fuel, ensuring the aircraft will not be…
Flight instruments provide the pilot with information about the flight situation of that aircraft, such as altitude, speed and direction; and are of particular use in conditions of poor visibility, su…
The force acting on an aircraft in opposition to gravity which keeps the aircraft in the air.
Different aircraft engines use different fuels; the most common types are Jet A or A-1 for jet and turboprop engines, and avgas for piston engines.
Piston (reciprocating) aircraft engines are internal combustion engines, similar to the type found in most automobiles. They are typically gasoline powered.
for questions about the FAA itself. Questions about FAA regulations should use the faa-regulations tag. The FAA (Federal Aviation Administration) is the agency responsible for regulating …
The 2D shape of a section of aircraft wing.
For questions specifically pertaining to pilots themselves, rather than aircraft or flying; use [career] instead where applicable.
Use in conjunction with a country tag, if a [regulations-country] tag does not yet exist
For questions about identifying a feature or design on an aircraft or airport.
Aerodynamic drag is the fluid drag force that acts on any moving solid body in the direction of the fluid freestream flow. Part of the drag is the direct consequence of the wing generating lift.
Airspace means the air above a specific country (e.g. US airspace) but for aviation purposes it is usually divided into different types, each of which may have different regulations.
EASA maintains the aviation laws for most of Europe. It contain rules pertaining to everything aviation-related: pilots, aircraft, maintenance, flight training, airlines and other commercial operat…
For questions relating to aviation accidents, or the avoidance thereof.
The wheels of an airplane. Sometimes replaced by floats or skis.
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot on board. Its flight is controlled either autonomously by computers in the vehicle or under the remote…
A type of jet engine which uses two different airflow streams (one passing through the core and another blown past it by a fan) for obtaining thrust.
The speed of an aircraft relative to the air. Among the common conventions for qualifying airspeed are: indicated airspeed ("IAS"), calibrated airspeed ("CAS"), true airspeed ("TAS"), equivalent airsp…
The phase of flight in which an aircraft is lining up with the runway and preparing to land.
A cockpit or flight deck is the area, usually near the front of an aircraft, from which a pilot controls the aircraft.
For questions relating to navigation charts, but not performance charts.
Questions about the process and principles used when designing aircraft engines. Use "jet-engine" and "piston-engine" tags to specify a certain type of engine.
Use for medical certification and aviation-related physiological and psychological factors; use [medevac] for medical evacuation aircraft and their procedures.
*Jet* is a generic, informal term for an aircraft with jet propulsion. In a civilian context it may refer to an airliner or small private jet.
The physics of maintaining a specific state in the dynamic system of aircraft flight.
A measurement of vertical distance. Usually measured at either Mean-Sea-Level (MSL) or Above-Ground-Level (AGL).
Visual flight rules (VFR) is a set of regulations governing aircraft operations. VFR permits flying and navigating by visual reference outside the aircraft.
A stall is an aerodynamic condition wherein the angle of attack of a wing increases beyond the "critical angle of attack", causing the wing to cease generating lift.
An autopilot is a system used to guide an aircraft without assistance from a person.
Use for questions relating to flight at speeds greater than sound and related effects from doing so.
Procedures for navigating based on cockpit instruments rather than visual references outside the cockpit.
is for obtaining licenses, certificates, and ratings. It includes the required paperwork and testing, but not the training (use [flight-training] instead).
Use for gliders; combine with specific tags, e.g. [sailplane], if required.
Efficiency is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result. In a more general sense, it is the abilit…
