Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace.
An aircraft is a machine that is able to fly by gaining support from the air.
Airspeed is the speed of an aircraft relative to the air.
Altitude or height (sometimes known as depth) is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, atmospheric pressure, and many more).
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating.
An Embraer ERJ 145 climbing In aviation, a climb is the operation of increasing the altitude of an aircraft.
In navigation, a vessel's or aircraft's course is the cardinal direction along which the vessel or aircraft is to be steered.
A descent during air travel is any portion where an aircraft decreases altitude, and is the opposite of an ascent or climb.
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
In aviation and aviation meteorology, a flight level (FL) is defined as a vertical altitude at standard pressure, nominally expressed in hundreds of feet.
Ground speed is the horizontal speed of an aircraft relative to the ground.
The knot is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.15078 mph).
A step climb in aviation is a series of altitude gains that improve fuel economy by moving into thinner air as an aircraft becomes lighter and becomes capable of faster, more economical flight.
Supercruise is sustained supersonic flight of a supersonic aircraft with a useful cargo, passenger, or weapons load performed efficiently, which typically precludes the use of highly inefficient afterburners or "reheat".
Takeoff is the phase of flight in which an aerospace vehicle or an animal goes from the ground to flying in the air.
In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft.
Visual flight rules (VFR) are a set of regulations under which a pilot operates an aircraft in weather conditions generally clear enough to allow the pilot to see where the aircraft is going.
